Drill Point Gage, Starrett

This gage was designed specifically for use in drill grinding. It provides a quick, accurate way for determining the correct drill point angle of 59° and the correct length of drill lips necessary for clean-cut drilling at maximum feeds and speeds.

The sliding head may be adjusted to any position along the rule and locked by a thumb nut.

The head is beveled to 59° (the correct drill point angle), and is also graduated in 32nds along the 59° face for measuring the drill lips which should be of equal lengths.

The hook rule has accurate, machine-divided graduations in 8ths, 16ths, quick-reading 32nds and 64ths.

Hook is adjustable and can be shortened or extended on either side of the rule, and may also be removed if desired.

Tool can also be used as a plain rule, hook rule, depth gage, and slide caliper. The No. 22D Head-only will fit all steel rules 3/4" wide by 3/64" thick.
