How many teeth does a back saw have?

A backsaw is a specialized handsaw for cutting tenons (joints or grooves) in wood. The blade is rectangular, 8 to 14 inches in length, with a hardwood or plastic handle and a metal-reinforced back edge (opposite the teeth) to keep the blade from bending while cutting. There are 11 to 20 teeth, or points, per inch.

Furthermore, how many teeth should a saw blade have?

Tooth Count In general, a blade with more teeth makes a smoother cut but runs hotter. To avoid overheating, three to five teeth should be engaged during a rip cut (see photo, right). For crosscuts and sheet goods, five to seven teeth should do the work.

Likewise, how many teeth does a dovetail saw have? Ideally you need to have around 5-6 teeth in contact with the timber to give a clean cut. Too few teeth will give a snatchy rough cut and too many teeth will be slow cutting and over-working the saw. Very fine boxmaking with thin material needs a saw of 25-42tpi.

Beside this, what is the difference between a back saw and a dovetail saw?

Tenon saw – a midsized backsaw. The saw derives its name from its use in the cutting of tenons for mortise and tenon joinery. Tenon saws are commonly available with rip-filed teeth for rip cutting and cross-cut for cutting across the grain. Dovetail saw – a small backsaw used to cut dovetails.

Is more teeth on a saw blade better?

In general, blades with more teeth yield a smoother cut, and blades with fewer teeth remove material faster. A crosscut blade makes many more individual cuts as it moves through the stock than a ripping blade and, as a result, requires a slower feed rate. The result is a cleaner cut on edges and a smoother cut surface.
