Somax Saw Set for 4-8 tpi

Somax saw set for setting the teeth of coarser hand saws with 4-8 TPI. Somax saw sets are graduated in TPI (teeth per inch) rather than tooth pitch in mm. This saw set has a 2.2 mm plunger and copes with teeth between 3 and 7 mm (8-4 TPI).

TPI to tooth pitch:
20 tpi = 1.25 mm
12 tpi = 2.1 mm
10 tpi = 2.5 mm
8 tpi = 3.2 mm
7 tpi = 3.6 mm
6 tpi = 4.2 mm
5 tpi = 5.1 mm
4 tpi = 6.4 mm

How to use: unscrew the knurled knob and turn the scaled ring (the anvil onto which the teeth are pressed) until the desired pitch appears as a TPI figure. If your saw has 3 mm teeth, set the ring at 8, because 8 tpi equals 3 mm teeth. Accuracy to decimal fractions is not necessary. For less set, use 10; for more, use 7.

Place the saw set on the teeth at one end of the blade so that the plunger points to the first tooth, and press the grip together. Pressed against the anvil by the plunger, the tooth is set. Do this to every second tooth along the blade, then turn the blade round and set the remaining teeth in the opposite direction.

Do not press the plunger against the scaled ring without a saw inside; the hardened plunger can make ugly notches in the ring. This does not affect function as long as the whole surface is not damaged. Use only light pressure when setting the teeth.
