Hand saws

Coping sawfor cutting wood patterns

Crosscut sawfor making cuts perpendicular to the grain

Fret sawfor cutting intricate wood patterns

Hacksawfine-toothed tempered blade under tension for cutting metal, bone, and other hard materials.

Pad saw,keyhole saw, jab saw narrow bladed saw.

Plywood sawfine-toothed blade to reduce tearing of plywood

Rip sawfor cutting along the grain

Two-man sawfor cutting large logs or trees

Veneer sawtwo edged saw with fine teeth used to cut veneer

Miter sawused to make accurate crosscuts and miters in a workpiece

Tenon sawalso called aDovetail sawor sash saw is used in woodworking for precise work

Mechanically powered saws

Circular saw, used in industrial sawing of log and beams, typically found in sawmills

also name given to smaller hand-held saws

Table saw, circular blade rising through a slot in a table. A smaller direct-drive versions can be set on a

workbench is called workbench saw. If set on steel legs it is called a Contractor's Saw. A heavier version,

which is more precise and more powerful and driven by multiple belts with an enclosed base stand is called a

Cabinet saw. A new version, called a hybrid saw, has the lighter weight mechanism of a Contractor saw but

with an enclosed base like the Cabinet saw.

Radial arm sawis a versatile machine used mainly for cross-cutting. The blade is pulled on a guide arm

through a piece of wood held stationary on the saw's table

Rotary sawis used to make accurate cuts without the need for a pilot hole in wallboard, plywood, and other

thin materials. It can be called a spiral cut saw or a "RotoZip".

Electric miter saw, (also called chop saw, cut-off saw or power miter box) is used for making accurate cross

cuts and miter cuts. The basic model has its circular blade fixed at a 90 angle to the vertical, a compound

miter saw's blade can be adjusted to other angles. A sliding compound miter saw has a blade which can be

pulled through the work similar to the action of a radial arm saw, which gives a greater capacity for cutting

wider workpieces.

Concrete saw, usually powered by an internal combustion engine and used with a Diamond Blade to cut

concrete or asphalt pavement.

Abrasive saw, which uses an abrasive disc for cutting rather than a toothed blade. Abrasive saws are used for

cutting very hard materials, such as metal.

Pendulum saworSwing saw, the saw is hung on a swinging arm. Often used for roughcross cuttingwoodin a

sawmill. Also for cutting ice out of afrozenriver.

Jigsawor saber saw (US) has a narrow blade for cutting irregular shapes. The term jigsaw was also

commonly used for what is now called a scroll saw.

2/3

Reciprocating saworsabre saw(UK and Australia) use an action similar to a jigsaw. They are larger, more

powerful and use a longer stroke with the blade parallel to the barrel. It is useful for demolition work or for

cutting pipe, and is sometimes powered by compressed air.

Scroll sawis a saw for making intricate curved cuts (scrolls).

Dragsawis used for bucking logs before the advent of the chainsaw.

Sternal sawis used in surgery to open a patient's sternum.

Continuous band blades

Band saw, withmotor-driven continuous band

Chainsaw,motor-driven, for fellingtrees

Types of blades

Blade teeth are of two general types: Tool steel or carbide. Carbide is harder and holds a sharp edge much longer.

Band saw blade

A long band with teeth on one side welded into a circle. Less waste than circular saws due to blade being

thinner. More heat disapation because there is more blade to do the cutting. Usually run at a slower speed

than circular saw.

Crosscut

Inwoodworking, a cut made at (or near) a right angle to the direction of thewood grainof the workpiece. A

crosscut sawis used to make this type of cut.

Rip cut

In woodworking, a cut made parallel to the direction of the grain of the workpiece. Arip sawis used to

make this type of cut.

Plytooth

A circular saw blade with many small teeth designed for cuttingplywoodwith minimal splintering.

Dado blade

A special type of circular saw blade used for making wide grooved cuts in wood so the edge of another

piece of wood will fit into the groove to make a joint. Dado blades can make different width grooves by

addition or removal of chipper blades of various widths between the outer dado blades. This first type is

called a stacked dado blade. There is another type of dado blade capable of cutting variable width

grooves. An adjustable dado utilizes a movable locking cam mechanism which causes the blade to wobble

sideways more or less. This allows continuously variable groove width from the lower to upper design

limits of the dado.

Strob Saw Blade

A circular saw blade with special rakers/cutters to easily saw through green or uncured wood which would

otherwise jam the saw blade.

Materials used for saws

There are several materials used in saws, with each of its own specifications.

7/29/2019 Types of Hand saws

3/3

Brass

Mostly used inback sawsbecause of its low price, its flow characteristics that make the material relatively

easy to cast, and unlike other types of saw, the forces that take place in back saws are relatively low

because of the pulling motion used.

Steel

Used in almost every existing kind of saw. Because steel is cheap, easy to shape, and very strong, it has

the right properties for most kind of saws.

Diamond

Fixed onto the saw blade's base to formdiamond saw blades. As diamond is asuperhard material, diamond

saw blades can be used to cut hard and brittle, or abrasive materials, for example, stone, concrete,

asphalt, bricks, ceramics, glass, semiconductor and gem stone. There are many methods to fix the

diamonds onto the blades' base and there are various diamond saw blades, which are used in a variety of

fields.[8]

High speed steel(HSS)

The whole saw blade is made of High Speed Steel (HSS). HSS saw blades are mainly used to cut steel,

copper, aluminum and other metal materials. If high-strength steels (e.g., stainless steel) are to be cut, theblades made of cobalt HSS (e.g. M35, M42) should be used.[8]

Tungsten carbide

Normally, there are two ways to use tungsten carbide to make saw blades:[8]

1. Carbide tipped saw blades: The saw blade's teeth are tipped (via welding) with small pieces of sharp

tungsten carbide block. This type of blade is also called TCT (Tungsten Carbide Tipped) saw blade. Carbide

tipped saw blades are widely used to cut wood, plywood, laminated board, plastic, grass, aluminum and some

other metals.

2. Solid carbide saw blades: The whole saw blade is made of tungsten carbide. Comparing with HSS saw

blades, solid carbide saw blades have higher hardness under high temperatures, and are more durable, butthey also have a lower toughness.

Uses of Saw Blades

Saws are most commonly used for cutting hard materials. They are used extensively in forestry, construction,

demolition, medicine, and hunting.

Musical sawsare used as instruments to make music.

Chainsaw carvingis a flourishing modern art form. Special saws have been developed for this purpose.

The production ofLumber, lengths of squared wood for use in construction, begins with the felling of trees and

the transportation of the logs to asawmill.

Plainsawing:Lumberfor structural uses is typically plainsawn (also called flatsawn), a method of dividing the log that

produces the maximum yield of useful pieces and therefore the greatest economy.

Quarter sawing: This sawing method produce edge-grain or vertical gainlumber, in which annual growth rings run more

consistently perpendicular to the pieces' wider faces
