Harvey Tool 27432-C3 Drill Mill 1/2 in 4 Flute Solid Carbide

Product Description

The HARVEY TOOL 27432-C3 is a solid carbide drill mill designed for machinists and tooling professionals who need a single tool capable of drilling, chamfering, and end milling in one operation. Built with 4 flutes and a 100-degree point angle, it handles both drilling entry and peripheral milling without a tool change. The 0.5 inch cutting diameter pairs with a 1 inch length of cut, giving it solid reach for slotting and profiling operations. An AlTiN coating improves heat resistance and tool life in ferrous and abrasive materials. Overall length is 3 inches, and the shank diameter matches the cutting diameter at 0.5 inch for straightforward collet clamping.

This drill mill is suited for CNC machining centers and manual mills in job shop, production, and toolroom environments. It handles applications in steel, stainless, cast iron, and hard alloys where the AlTiN finish provides thermal protection at higher cutting speeds. The 100-degree point angle makes it effective for spot drilling and countersinking in addition to end milling and plunge operations, reducing the number of tools required in a given setup.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 4-flute geometry supports both drilling and end milling in a single tool
• 100-degree point angle suitable for spot drilling, chamfering, and countersinking
• AlTiN coating extends tool life in ferrous and abrasive workpiece materials
• 0.5 inch shank diameter compatible with standard ER and end mill collet holders
• 3 inch overall length with 1 inch length of cut for reach in moderate-depth applications

Compatibility

Designed as an OEM-style replacement or direct-use drill mill for CNC machining centers and manual mills accepting 1/2 inch shank tooling with standard collet or end mill holders.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 0.5 inch shank in a properly sized collet or end mill holder and torque the retention mechanism per the holder manufacturer's specification. Confirm runout with a dial indicator before cutting. Power down the spindle completely before making any tool changes or adjustments.
