SDI-3090-PRH-Altin: #3 Insert Spot Drill 90°, Pos. Grind, RH, .036 Point Flat, Altin Coated

Highly repeatable, carbide ground inserts make old fashioned center drills obsolete for performing spotting operations. Precision ground carbide inserts repeat within +/- .0004"", thus eliminating the need to adjust the axial location of the tool, unlike conventional spot tooling held by collets. The system also simplifies tool changing in that it only requires a torx wrench for insert removal. This eliminates the need for collet wrenches, reducing the chance of accidental tool breakage or personal injury.
