Impregnated Bits

Boart Longyear introduces metal coated diamond impregnated bits -the latest in industrial diamond technology.• Significantly outperforms the successful Series range in both drilling

speed and bit life.• Protects the diamond from oxidation and surface degradation

during manufacturing.• Inhibits the premature "pull-out" of the diamond.• Increases the number of cutting edges exposed to the rock.• Available in multiple standard configurations and selected on the

basis of relative rock hardness and ground conditions.

Standard: Designed to handle a wide variety of formations.

Abrasive: Recommended for broken "abrasive" drilling condtions. Forharder rock with broken conditions use a higher number bit tomaintain good drilling speeds.

Competent: Free cutting design for fast penetration in very hard"competent" rock or for use on lower powered rigs and geotechnicalapplications.

Express Geometry: Bits are supplied with additional intermediatewaterways which provide increased flushing. The reduced bit facearea allows for higher penetration rates with less bit weight required.Recommended when polishing occurs with standard geometry.

NOTE: "Standard Gauge" bits are defined as having a set outsidediameter which is 0.48mm (0.019") smaller than "ReamingShell Gauge". For more detailed information on "StandardGauge vs Reaming Shell Gauge" impregnated bits, refer tothe ITHT Product Manual.

Thermally Stable Diamond (TSD) Bits

TSD Bits

HQ Thermally Stable Diamond Bit **

Thermally Stable Diamond (TSD) Bits:• Contains no natural diamonds in order to eliminate the possibility of

core sample contamination.• Inside and outside gauge diameter integrity is maintained with

heavily reinforced tungsten carbide particles (eliminates the needfor natural diamonds).

• Manufactured with a very erosion resistant matrix.• High penetration rates are common due to maximum setting

exposure of the TSD elements providing an aggressive cuttingface.

• Large waterways for improved flushing of large cuttings.

Triple-Tube Thermally Stable Diamond (TSD) Bits:• TSD triple-tube face discharge bits are used with Boart Longyear

triple-tube core barrels.• The design of the face discharge waterways and core lifter case

forces the majority of the discharge fluid to the bit face.• Core can be recovered and inspected in a virtually undisturbed

condition with the triple-tube system.

Applications:• TSD bits are commonly used for exploration of diamond bearing

Kimberlite formations.• Suitable for geotechnical drilling applications.• Although best suited for soft ground conditions, intermittent hard

ground can be tolerated.

**Available on special request.

Reaming Shells

The recommended practice is to alternate two reaming shells in eachhole drilled to maintain hole diameter. Upon bit changes, the reamingshell should be checked for wear with the bit and shell wear gauge.Failure to observe these recommended practices will result in either apoorly stabilized bit or an undersized hole that will require costlyreaming.

Casing Shoes

Casing ShoeThe inside diameter of the casing shoe is not set with diamonds andis flush with the inside diameter of the casing, permitting free passageof the core barrel past the casing shoe.

Applications:• The casing shoe is threaded to the end of the casing string for

penetration through overburden.• Assists in seating the casing into the bedrock, providing a tight

seal for the drilling fluids to flow through to the surface.• Used to ream the casing downward when advancing a casing

string in an existing hole with the rod string still in place.

Bit and Shell Gauge

Bit and Shell Gauge

HQ/HQ3 Bit and Shell Wear Gauge 30000

Bit and Shell Wear GaugeAs good practice, the diameter of surface set bits and reaming shellsshould be measured. This will ensure that the hole size is maintained.All holes should be collared with a full gauge reaming shell. Ondeeper holes, two or more shells should be alternated in the hole tomaintain the hole size. Reaming shells should be gauged every tripout of the hole.The practice of gauging bits is more common with surface set bits.Impregnated bits typically maintain their gauge until totally consumed.

Hard FacingIn order to improve the protection of the blank for bits, reaming shell,or casing shoes, three spiral strips of hard tungsten carbide can beapplied over the full length of the blank.

Super Flush WaterwaysWaterways designed to 6.35mm (0.25”) width to allow improvedpassage of drilling fluids.

Reinforced WaterwaysFor surface set bits, matrix protection can be provided by supplyingtungsten carbide inserts on the leading edge of the waterways.

Extra Hard MatrixFor more abrasive drilling conditions, an increased erosion resistantmatrix is available for surface set bits.

Non-Coring BitsTheir design provides reinforcement of the center of the bit to preventexcessive wear of this critical area. Various center designs, includingpencil core and crowsfoot types, are available to suit your particularneeds. Water courses are carefully engineered to provide fast andcomplete evacuation of the cuttings produced by this type of tool,thereby increasing the penetration rates in all types of formations andincreasing bit life. Other non-coring bits are available for hydroelectricgrouting applications.

Ordering Information

Boart Longyear has developed an innovative and practical approachto selecting the best core barrel for your drilling application. Thisapproach incorporates a standard core barrel consisting of the headassembly, inner tube components, outer tube components, the In-The-Hole Tools Product Manual and core barrel Safety Poster. Toorder the standard configuration core barrel, select a 1.5 m/5 ft or3.0 m/10 ft core barrel part number from the standard core barrelpage.

There are also options available for standard product which areindicated by a “ ”. A listing of the options available appears on thehead assembly, inner tube components, and outer tube componentssections. If you would like to substitute the standard product for theseoptions, select a 1.5 m/5 ft or 3.0 m/10 ft core barrel part number fromthe standard core barrel page and specify all optional parts and partnumbers from the head assembly, inner tube components and/orouter tube components sections.


Core barrel parts are packaged exclusively to provide the customerwith the ability to assemble the core barrel with the ideal configurationto the drilling application.

The head assembly is shipped assembled with landing indication(surface head assembly only) and hard shut-off valves as standardproducts. If options are requested for the head assembly, they areshipped as separate items (not installed) and must be installed by theend user. If options are ordered for the inner tube and outer tubecomponents, they will replace the standard component.

The standard surface head assembly is supplied

with landing indication. Landing indication must be reset by poppingthe ball back through the bushing after each use (see the ITHTProduct Manual). If you do not wish to use landing indication, it mustbe removed or slow descent times may result.

If you haveordered the optional fluid retention kit, place the spring, the fluidretention bushing, and the stainless steel ball into the lower latch bodyin this order. Reassemble the upper and lower latch body.

NOTE: For the Dry Hole Valve option, refer to the ITHT Product Manualfor detailed instructions.

If the optional soft shut-off valves are ordered, remove the inner tubecap assembly to expose the stover lock nut on the end of the spindle.Remove the nut and all the components on the spindle shaft, replacethe hard shut-off valves with the soft and reassemble.

NOTE: Ensure that the thrust and hanger bearings are reinstalled thesame way that they were removed in order to retain properlubrication pathways.

If the standard head assembly is to be used, no changes are requiredand it is ready to be added to the inner tube components.

of the core lifter.2) Insert the core lifter into the core lifter case from the threaded end.3) Insert the stop ring into the grooved recess of the core lifter case.4) Apply grease to the threaded ends of the head assembly, core

lifter case and inner tube.5) Thread the head assembly to one end of the inner tube and the

core lifter case to the other. Use an inner tube wrench to ensurethe joints are snug.

Outer Tube Components1) Apply grease to the outside of the landing ring, the recess in the

outer tube, and all threaded joints.2) If the core barrel is intended for storage, insert the inner tube

stabilizer into the thread protector and assemble to one end of theouter tube. If the core barrel is intended for immediate use, insertthe inner tube stabilizer into a reaming shell and thread thereaming shell onto the end of the outer tube.

3) Insert the landing ring into the recess of the outer tube.4) Thread the adapter coupling onto the other end of the outer tube.5) Thread the locking coupling onto the adapter coupling.6) Tighten all joints with an outer tube wrench to ensure they are

snug.

Core Barrel1) Insert the assembled inner tube components into the assembled

outer tube components.NOTE: Assembly is easier if the bit end of the core barrel islower than the locking coupling end.

2) Retract the latches of the head assembly to allow them to enter thebox threads of the locking coupling. The loading sleeve isrecommended for loading the inner tube into the core barrel outertube assembly or rod string.

3) When the landing shoulder of the head assembly is seated on thelanding ring of the outer tube components, there is sufficient roomfor the latches to reopen. This locks the inner tube componentsinside the outer tube components.

NOTE: For complete operating instructions, refer to the ITHT ProductManual that is shipped with every core barrel.Clearly post the safety poster in your work area.

NOTE: The locking sleeve (#17) is sold as an assembled component ofthe overshot and is held in place by the set screw (#17) forshipping purposes. The locking sleeve MUST BE REMOVEDfor normal operation or the lifting dogs will be locked openand will fail to retrieve the inner tube assembly.

Dry Hole LoweringIn “dry holes”, the overshot assembly is used with the locking sleeveto lower the inner tube assembly. If the dry hole lowering cap isinstalled on the overshot and the washers are installed under thecore barrel spearhead, the locking sleeve will not release the innertube assembly until it has latched. Otherwise, it will release uponcontact with water or any form of resistance. The taper on the corebarrel spearhead base forces the top end of the lifting dogs inward,allowing the locking sleeve to drop down and lock the lifting dogsopen. The set screw (#16) can be used when dry hole lowering toprevent the locking sleeve from moving off the overshot.

If the dry hole lowering cap or washers are not

installed, the inner tube assembly can be released prematurely if itencounters resistance inside the rod string that resembles contactwith the water table or landing shoulder, i.e. bulged/damaged rodjoints.

Releasing the Overshot AssemblyIf the inner tube assembly becomes stuck in the outer tube, thelocking sleeve is used to release the overshot. The locking sleeve isguided onto the wireline cable through the guide slot and dropped tothe overshot/inner tube assembly. The locking sleeve drops over thelifting dogs and locks them open to allow the overshot to be pulled offthe core barrel spearhead point.

RQ®HP high performance drill rod:• Unsurpassed joint performance with “low stress” RQ® thread

design.• Super strong thru-wall hardened box and pin ends.• Exclusive electric induction surface hardening for superior wear

resistance.• Increased thread life with electric induction surface hardened pin

thread crests and thru-wall hardened box threads.• Tight mechanical seal reducing fluid loss.• Increased joint taper and unique thread lead-in reducing cross

threading and jamming.• Z-50 Thread Compound (p/n 306486, 8 kg pail) is the

recommended thread lubricant to reduce wear and the possibility ofgalling during drilling operations.

• To reduce the friction between the walls of the hole and the drillrod, apply rod grease (p/n 62796) to the surface of the drill rods.Rod grease also reduces in-hole vibration, increasing tool andequipment service life.

Drill rods MUST be pretorqued with the minimum recommendedmake-up torque to preload the box and pin prior to drilling. Drillingtorque alone will not make-up the joint. Drilling operating torqueshould never exceed make-up torque.

NOTE: Rod capacities and failure loads were determined by independent facility. Asafety factor has been applied for the above ratings (applies to new, unusedBoart Longyear rods, in a straight vertical down hole, assuming complianceto ITHT Product Manual and standard core drilling practices).Burst and collapse pressure ratings will be reduced under drilling loads.Operating torque should not exceed make-up torque.* Increase make-up torque to match operating torque as depth increases.** These failure loads are for product comparison purposes ONLY. Drilling

loads should not exceed rating values.
