Harvey Tool 881124-C6 Drill Mill 3/8 in 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 881124-C6 is a solid carbide drill mill designed for multi-operation machining in a single tool. It combines drilling and milling capability in one setup, reducing tool changes and cycle time in milling machines and machining centers. The 881124-C6 features a 90-degree point angle, 4 flutes, and an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life in ferrous and hardened materials. With a 3/8-inch diameter and 7/8-inch length of cut, it handles both spot drilling and side milling operations in compact workspaces. Installed by machinists and tooling professionals in CNC and manual milling environments.

This drill mill is suited for production and job-shop applications in ferrous metals, stainless steels, and hardened materials where the AlTiN coating provides a thermal barrier at elevated cutting speeds. The 90-degree point angle makes it effective for spot drilling, countersinking, and chamfering in addition to end milling. The 3/8-inch shank fits standard ER collet chucks, end mill holders, and shrink-fit tooling systems used in vertical and horizontal machining centers. Its 2-1/2-inch overall length provides adequate reach for most standard fixturing setups without sacrificing rigidity.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves heat resistance and extends tool life at higher cutting speeds
• 90-degree point angle enables spot drilling, chamfering, and countersinking in addition to end milling
• 4-flute geometry supports efficient chip evacuation and smooth surface finish
• 3/8-inch shank diameter fits common ER collet and end mill holder systems
• 7/8-inch length of cut accommodates standard milling depths in one pass

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting 3/8-inch shank end mill toolholders.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before loading or changing tooling. Seat the shank fully into the collet or toolholder and torque the retention hardware per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning cutting operations to avoid premature tool wear or breakage.
