SDH-3D-625-3.0: #3 Insert Spot Drill Holder Double Ended .625'' dia. shank x 3'' OAL

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.
