Harvey Tool 15424-C3 Drill Mill 3/8 in 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 15424-C3 is a solid carbide drill mill designed to perform both drilling and milling operations in a single tool. With a 3/8 inch diameter and a 60-degree point angle, it transitions cleanly between center drilling, spotting, chamfering, and peripheral milling without a tool change. The 4-flute geometry supports aggressive material removal while maintaining rigidity. An AlTiN coating improves heat resistance and extends tool life in ferrous and hard materials. Overall length is 2.5 inches with a 7/8 inch length of cut. Machinists and toolroom operators use this style of cutter when cycle time and tool count both matter.

This drill mill is suited for use in CNC machining centers and manual mills where multi-function tooling reduces setup time. Typical applications include spotting hole locations, drilling through softer workpieces, countersinking, and end milling features in the same operation. The AlTiN finish makes it a practical choice for stainless steels, alloy steels, hardened materials, and cast iron. Shank diameter matches the cutter diameter at 3/8 inch, fitting standard ER and rigid collet systems without a reducer.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides elevated heat resistance and extended tool life
• 60-degree point angle suited for spotting, chamfering, and drilling entry
• 4-flute design balances chip evacuation with surface finish quality
• 3/8 inch shank matches cutter diameter for direct collet mounting
• Handles drilling, spotting, chamfering, and milling in one tool

Compatibility

Designed for use in CNC machining centers and manual knee mills equipped with standard collet systems accepting a 3/8 inch shank. Verify spindle speed and feed rate against workpiece material before use.

Installation Notes

Installation requires a properly sized collet or end mill holder rated for the 3/8 inch shank diameter. Power down the spindle and confirm it has come to a full stop before changing tooling. Ensure the shank is fully seated and the collet nut is torqued according to the holder manufacturer specifications. A licensed machinist or qualified toolroom operator should verify runout with a dial indicator before production use.
