Harvey Tool 950516-C3 Drill Mill 1/4 in 2 Flute Altin Carbide

Product Description

The HARVEY TOOL 950516-C3 is a solid carbide drill mill designed for operations that combine drilling and milling in a single tool pass. With a 1/4 inch cutting diameter, a 140-degree point angle, and an AlTiN coating, this tool handles both center drilling and peripheral milling without a tool change. The two-flute geometry provides efficient chip evacuation in ferrous and nonferrous materials. The AlTiN finish extends tool life at elevated cutting temperatures, making it well suited for harder materials and dry or semi-dry machining environments. Machinists and CNC operators use this tool to reduce setup time and improve hole-feature accuracy in production and prototype work.

This drill mill is intended for use in CNC machining centers and manual mills where a single tool must perform drilling, chamfering, spotting, and light milling operations. The 1/4 inch shank diameter fits standard ER collet chucks, end mill holders, and drill chucks rated for that bore size. It is commonly applied in job shop, aerospace, medical device, and general metalworking environments where multi-function tooling reduces cycle time. The 3/4 inch length of cut provides adequate reach for shallow-to-moderate depth features without sacrificing rigidity.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating enhances heat resistance and extends tool life in harder alloys
• 140-degree point angle optimized for drilling entry and transition to side milling
• Two-flute design promotes efficient chip evacuation in both drilling and milling modes
• 1/4 inch shank diameter is compatible with common collet and end mill holder systems
• Compact 3/4 inch length of cut maintains stiffness and reduces deflection at depth

Compatibility

Designed as an OEM-style replacement and standard fitment drill mill for CNC machining centers and manual milling machines accepting a 1/4 inch shank diameter toolholder.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Secure the shank fully into the collet or toolholder and torque the retention system per the toolholder manufacturer specifications before spindle engagement. Verify runout with a dial indicator before production cuts, as excessive runout accelerates edge wear on carbide tooling. Do not use this tool as a plunge drill at angles outside its design geometry without confirming the manufacturer application guidelines.
