Harvey Tool 15432 Drill Mill 1/2 in 4 Flute 60 Pt Carbide

Product Description

The HARVEY TOOL 15432 is a solid carbide drill mill designed for combined drilling and milling operations in a single setup. With a 1/2-inch cutting diameter, a 1-inch length of cut, and a 60-degree point angle, this tool transitions cleanly between plunge drilling and peripheral milling without a tool change. The four-flute geometry improves chip evacuation and surface finish during side milling passes. The uncoated solid carbide construction provides rigidity and edge retention across a range of ferrous and non-ferrous workpiece materials. It is used by machinists and tool-and-die professionals working on CNC mills and machining centers.

The 15432 is suited for job shop, production, and prototype machining environments where reducing cycle time through combined drilling and milling operations is a priority. Its 1/2-inch shank diameter makes it compatible with standard ER collet chucks, end mill holders, and shrink-fit toolholders commonly found on vertical and horizontal machining centers. The 3-inch overall length provides reach for moderate-depth features while maintaining adequate stiffness to minimize deflection during cuts.

Key Features

• 1/2-inch cutting diameter with matching 1/2-inch shank for direct collet or holder mounting
• 60-degree point angle enables accurate plunge entry and center-cutting capability
• 1-inch length of cut supports milling of slots, pockets, and angled features
• 4-flute design balances chip clearance with surface finish in milling passes
• Solid carbide construction delivers hardness and rigidity for consistent tool life
• Uncoated finish suitable for use with cutting fluid on a broad range of materials

Compatibility

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

Installation Notes

Installation and use of this tool should be performed by qualified machinists familiar with CNC or manual milling operations. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool from its holder. Verify holder runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear and degrades hole quality. Follow machine manufacturer guidelines and applicable shop safety codes when programming spindle speeds and feed rates.
