Harvey Tool 991702-C3 Drill Mill 2 Flute 60 Point Carbide

Product Description

The HARVEY TOOL 991702-C3 is a solid carbide drill mill designed for combined drilling and milling operations in a single tool. With a 60-degree point angle and 2 flutes, it drills entry holes and transitions directly into profile or slot milling without a tool change. The cutting diameter is 0.0312 inches, making it suited for fine-detail work in ferrous and non-ferrous materials. The AlTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions. Licensed machinists and CNC programmers specify this tool when tight tolerances and minimal tool changes are priorities in production or prototype environments.

This drill mill fits applications requiring small-diameter combined drilling and end milling, including mold and die work, medical component machining, and precision aerospace part production. The 3/32-inch length of cut and 1/8-inch shank diameter make it compatible with standard collet chucks and small-bore toolholders commonly found on CNC machining centers and vertical mills. The 1-1/2-inch overall length provides adequate reach for most shallow-pocket and surface-feature applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• 60-degree point angle enables accurate drill entry before transitioning to milling
• AlTiN coating provides high-temperature oxidation resistance for extended tool life
• 2-flute geometry supports chip evacuation in both drilling and milling modes
• 0.0312-inch cutting diameter suits fine-feature and small-scale machining work
• 1/8-inch shank fits standard collet and toolholder systems without adapters

Compatibility

Designed for use in CNC machining centers and manual vertical mills accepting a 1/8-inch shank collet or toolholder. Suitable for ferrous and non-ferrous materials where an AlTiN coating is appropriate.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet. Seat the shank fully to the depth mark or toolholder specification and torque the collet nut per the toolholder manufacturer guidelines. Verify runout with a dial indicator after seating, as small-diameter carbide tools are sensitive to concentricity errors that can cause premature breakage.
