SDI-3090-NRM-T15-TLN: #3 Insert Spot Drill 90 Degree, Neg. Grind,RH,.015 Point Flat,T15 HSS

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.
