This publication may not, in part or whole, be reproduced without the editors approval. The publishers cannot be held responsible

for any errors, omissions or changes of any kind.

For safety reasons it is very important, that a drill does not exceed a speed of n=6000 rev./min. when un-supported. The centrifugal forces can break these long tools before reaching the workpiece.

Application recommendations for Carbide Drills Type TS 100 7xD, 10xD and 12xD

Pilot holes are necessary for extra length tools ≥ 7xD

The pilot hole can be produced with a short, rigid drill. The diameter should be 0.01 – 0.02 mm larger than the diameter of the extra length tool, the drill depth ≥ 1xD.

Alternatively the drill can produce their own pilot hole. Cutting speed and feed rate should be reduced by 30 – 40%.

The recommended minimum coolant pressure is40 bar.

More detailed information about the drills in our appli-cation recommendations you will find in the up-to-date issues of our catalogue and brochures, we will send to you on request.

for Multiplex-Twist Drillswith internal Coolant Duct

Drilling emulsion can be used as a coolant lubricant when drilling with interchargeable blades made of HSS-Co and Carbide; it can be used in the usual proportions of 1:20.It is absolutely essential here that you use a high-performace coolant aggregate. If there is insufficient coolant pressure and quantity, the drilling surface may be poor or the tool may even be damaged. If possible, the solid particles in the coolant shold not be larger than 50 µm.

Machine and WorkpieceOnly the stability of the machine, spindle, workpiece clamping and the workpiece itself allows the use of tungsten carbide bla-des. Insufficient rigidity leads to vibrations or "sagging" of the drill in the case of through holes, when the chisel edge emerges from the workpiece. Short tool life or tool breakage can result.

Drive RatingTo drive the machine, approx. 2.5 - 25 kW are required,depending on the hole diameter, the cutting values and the material to be drilled.

Coolant EquipmentThe availability of an efficient coolant equipment is essential. If pressure and quantity are insufficient, this may lead to bad surfaces or even breakages. The size of the solid components should not exceed 50 µm if possible (see diagram page 65).

Chip FormationFor general structural steel it is possible that unfavourable chip forms may occur, i.e. long and upset chips. These may obstruct the flutes and can cause the tool to break. This can however be counteracted to some extent by altering the cutting speed and feed. It is necessary to determine this through experiments, due to the fact that the chip formation with general structural steel depends on the range of cutting properties of the various batches. Similar unfavourable chip forms may be produced with corrosion and acid resistant steels.

General Instructions forTwist Drills with Interchangeable InsertsSystem Multiplex

Pow

er in

kW

Drilling pre-drilled holesAs the Multiplex system is guided predominantly by the chisel edge, it is not suitable for drilling pre-cast or pre-drilled holes.However, if the system is applied under the aforementioned conditions, the cutting parameters should be reduced.

Interrupted cuttingThe Multiplex system is not suitable for interrupted cutting(i.e. transverse holes that are larger than the drill diameter).

CenteringThe inserts for the Multiplex system are web thinned. Therefore, centering is only necessary for larger drilling depths. If centering is necessary for technical reasons, the centering point angle must be equal or larger than the point angle of the insert.The following applies: up to d = 25.4 mm = 135° up to d = 66.0 mm = 132° from d = 66.0 mm = 140°A short holder (3xD) may also be applied for centering.

Drill running off centerA drill running off center can be due to several factors. Anapproximate value of 0.1-0.16 mm for drilling depths up to 7xD is accepted as the norm. In this case the shortest possible and therefore the most rigid holder type should be applied.

Coolant pressureThe coolant used with the Multiplex system is extremely important for the chip evacuation. It can be delivered at a pressure of approx. 5 bar. Generally, the following rule applies. The more coolant available, the better.Through the use of coolant collars or coolant feed chucks, the Multiplex system can also be applied on older machines with exis-ting external cooling. One of our technical engineers wilI gladly find a solution to your specific application task.

Heavy cutting edge wearIf heat has eroded the corners, the cutting speed is too high and has to be reduced. Measure the unaffected diameter and re-calculate the cutting speed based on this new diameter.Subtract 10% from resulting speed and enter the value into the machine.

When deep-hole drilling, special care must be taken to supply sufficient coolant to the drill point. The drill point is sufficiently cooled by removing swarf one or several times from the hole. The frequency of swarf removal is mainly dependant on the workpiece material, the drill hole depth an the drill type.When using deep-hole drills with flat flute sections (FN), there is a marked reduction in swarf removal frequency. With some ma-terials, the swarf shape can be influenced by changing the point angle. The correct chip shape improves both swarf removal and coolant feed. The use of oil-feed drills with internal coolant supply is recommended for extremely deep holes or when drilling horizontally.

The data listed are intended as a guide and represent average values.

The tasks of the coolant (KSS):• chip evacuation

insufficient coolant leads to chip congestion and results in tool breakages• lubricating film

especially with single-fluted gun drills high surface pressure is created between hole and supporting strips. A break in the lubricating film causes excessive friction leading to tool breakages.

• cooling the cutting edgesduring the cutting process, temperatures of approx. 800° C are created at the carbide cutting edge, insufficient cooling drastically reduces tool life.

• high cutting rates at hardened materials (substitution of grinding)• dry machining possible (even at high cutting rates)• excellent surface quality and easy forming• replacement of grinding machine possible• reduction of production costs (coolant)• increased productivity

Limits for PCB:• Chemical Reactions

With austenitic steels and with cast iron with high content of free ferrite chemical reactions can result from γ and α ferric phases that decrease tool life

• Economy PCB is recommended to machine materials with hardness > 45 HRC. To machine materials with lower hardness other cutting materials are more economic.

• Pre-conditions for use: Conditions of machine and spindle. Vibration of workpiece in setting.

Capacitance of machineGuidelines for the load capacity of machine with carbide drills type TS 100 can be found in the diagrams on these pages.In relation to the tool diameter the engineer may use these illustrations to determine the following simply and quickly:- whether or not his machine spindle will be axially overloaded - the drive power and- the required torque.The minimum values (curves) refer to cutting procedures with a new tool, whereas maximum values refer to a worn tool shortly before the end of its edge life.

The occuring stress is illustrated for steel, cast iron and AlSi-alloys. This shows that the stresses with AlSi7 may be lower, however, the machine must be capable of meeting the required values at relatively high revolutions.

Core drilling of pre-drilled or pre-cast holes: the drill hooks in, is pulled out of the taper and the tang shears offOverheating of drill point caused by exces-sive cutting speed or insufficient cooling.Excessive feed when deep drilling

Drill is badly ground and lips are of different length.

Drill is blunt. Burrs at exit may be caused by absence of support when drilling and excessive feed-when drilling through holes.

Drill was blunt, feed was excessive or lubri-cation insufficient.

Workpiece was moun-ted at an angle or failed to lie flat because the support was not flat there where cuttings under the workpiece, the support or under the vice.

Excessive feed.The workpiece therefore became bent to mirror the bow of the drill or machine. Drill point not on hole centre. Drill vibrating.

Drill is vibrating or work-piece is badly aligned with drill point when spot drilling.

Web thinned chisel edge with modified lip acc. to DIN 1412 B (to reduce the rake angle)Reduce cutting speed (rpm). Ensure sufficient cooling. Reduce feed with drilling.

Regrind drill corretly using a gauge or mount on a special machine (preferred).Only use sharp, ground drills and suitable ba-cking supports. Reduce when drilling through holes.

Regrind drill, reduce feed, supply suitable lubricant quantities

Place workpiece in vice at same height or on top of a flat support.Remove cuttings from drilling table.

Reduce feed. Align drill point. Ensure drill runs true.

Insert drill so that it runs straight and align work-piece to the drill point before spot drilling.

Types of wear

Normal wear on lips (flank wear) and normal chisel edge wear. When regrinding, shorten the drill point until wear marks are removed from lands.

Excessive blunting of lips indicates exces-sive cutting speed. Tool life is drastically reduced. If this drill is further used for drilling, the cutting edges will glow and the material will weld to the drill.

The deformed chisel edges indicate drilling with excessive feed. A high feed only produces good tool life if the swarf can flow smoothly and unhindered along the flutes.

Premature blunting of chisel edges indi-cates drilling with an excessive feed. After severe deformation of the chisel edge, the lips will also become blunt if the drill is used without resharpening

If crater wear occurs after using the drill for a long time, it is an indication of well selected machining conditions. A smooth face reduces crater wear. However, built-up edge occur with a small rake angle. This is caused by insufficient cooling, primarily with soft materials.

Coatings andSurface Finishes

Due to their basically good properties, high speed steel and carbide tools are supplied without being surface treated, i.e. in bright finish. For special applications it is desirable to increase the durability and to reduce the sliding resistance and tendency of cold welding by special surface refining process.

Further surface treatmentsThe following surface treatments loose more and more in significance. Generally much better results you get with hard- or softcoated tools

1. NitridingNitriding is a further means of increasing the durability of tools. This finish is recommended for the machining of grey cast iron, aluminium with a high silicon content, plastics, steels with a high perlite content etc.

2. Hard-chromium platingTools that are treated in such a way especially reduce the sliding resistance and thus the cutting forces. These advantages will however be lost if, during the machine process, the temperature of 250°C is exceeded.

3. Steam temperingSteam tempered tools also offer a reduction in sliding resistance. Thus cold welding which occurs for example during the machining of steels that have a low carbon content, can be avoided most economically. Steam tempered tools are only suitable for ferrous materials.

4. BurnishingBurnishing is achieved in liquid solutions at temperatures above or close to 100°C. The solution contains oxidising substances such as nitrite, nitrate and/or colour dyes (i.e. phosphates). The low operating temperatures do not impair the tensile strength of steels which have a low resistance to tempering.

Variants of coatingsWhen coating our tools we differentiate between hard coatings: TiN (T-coat), TiAlN (A-coat), AlTiN (Super A-coat), TiCN (C-coat), FIRE (F-coat), and soft coatings: MolyGlide® (M-coat). Each coating offers very interesting advantages for certain applications.

T-coat or TiN-coat (Titanium Nitride)Physical appearance: golden colourWell proven, cost efficient all-round coat. Generally achieving performance increases of 400% on average. Surpassed in certain cases only by A- and C-coats.

A-coat or TiAlN-coat (Titanium Aluminium Nitride)Physical appearance: black-violet colourA special coat for machining abrasive materials (cast iron, AlSi) and/or working at high temperatures, i.e. in applications without coolant or with limited coolant facilities, such as deep or small diamter holes. Of importance is that the A-coat only achieves performance increases at higher machining rates.

SuperA-coat or AlTiN-coat (Aluminium Titanium Nitride)Physical appearance: violetThe well established A coating has been developed in our com-pany. By optimizing the structural, chemical and mechanical properties of the new Super-A coating, an extremely high hot hardness, very good oxidation resistance and excellent coating adhesion have been achieved. This coating is used exclusively on carbide cutting tools and is ideally suited for difficult-to-machine materials such as titanium alloys, Inconel as well as machining hardened steel materials (>52HRC) and HSC applications.

C-coat or TiCN-coat (Titanium Carbon Nitride)Physical appearance: grey-violet colourMulti-layered coat with laminar structure. Brings obvious advan-tages in steel machining operations, in difficult-to-machine materi-als or whenever demands as to hardness and toughness are above averages.

F-coat or FIRE-coatPhysical appearance: red-violet colourMulti-layered TiAlN-coating. Allround coating, combines the advantages of TiN-, TiAlN- and TiCN-coatings. Excellent "fire-resistant" heat resistance. Considerably better than TiN. High toughness.

M-coat or MolyGlide®-coat based on MoS2Physical appearance: dark-olive colourPatented soft coating, a glide coating especially developed to improve chip transportation and eliminate built-up edge when machining Al alloys. Combined with the A-coat, tool life on average can be doubled. But also dry HSC machining of steel can be achieved with the M-coat.

This publication may not, in part or whole, be reproduced without the editors approval. The publishers cannot be held responsible

for any errors, omissions or changes of any kind.

For safety reasons it is very important, that a drill does not exceed a speed of n=6000 rev./min. when un-supported. The centrifugal forces can break these long tools before reaching the workpiece.

Application recommendations for Carbide Drills Type TS 100 7xD, 10xD and 12xD

Pilot holes are necessary for extra length tools ≥ 7xD

The pilot hole can be produced with a short, rigid drill. The diameter should be 0.01 – 0.02 mm larger than the diameter of the extra length tool, the drill depth ≥ 1xD.

Alternatively the drill can produce their own pilot hole. Cutting speed and feed rate should be reduced by 30 – 40%.

The recommended minimum coolant pressure is40 bar.

More detailed information about the drills in our appli-cation recommendations you will find in the up-to-date issues of our catalogue and brochures, we will send to you on request.

Drilling emulsion can be used as a coolant lubricant when drilling with interchargeable blades made of HSS-Co and Carbide; it can be used in the usual proportions of 1:20.It is absolutely essential here that you use a high-performace coolant aggregate. If there is insufficient coolant pressure and quantity, the drilling surface may be poor or the tool may even be damaged. If possible, the solid particles in the coolant shold not be larger than 50 µm.
