Harvey Tool 928516 Drill Mill 1/4 in 2 Flute Solid Carbide

Product Description

The HARVEY TOOL 928516 is a solid carbide drill mill designed to perform both drilling and milling operations in a single tool. With a 1/4 inch cutting diameter and a 100-degree point angle, it transitions cleanly from plunge drilling to peripheral milling without a tool change. The 2-flute geometry provides efficient chip evacuation in a wide range of workpiece materials. The uncoated solid carbide construction delivers consistent rigidity and edge retention in general-purpose machining applications. Machinists and tool-and-die professionals working on CNC machining centers and manual mills rely on this tool for combination drilling and profiling work.

The 928516 is suited for light-to-medium duty machining operations on metals, plastics, and composite materials. The 3/4 inch length of cut supports shallow pockets, slots, and chamfered hole entries. The 1/4 inch shank diameter fits standard ER and end mill collet systems. This tool is appropriate for job shop, production, and prototype machining environments where multi-operation efficiency matters.

Key Features

• Solid carbide construction for rigidity and edge retention
• 100-degree point angle enables clean plunge entry and spot drilling
• 2-flute design promotes chip clearance in drilling and milling passes
• Uncoated finish suitable for use with cutting fluid or dry on non-ferrous materials
• 1/4 inch shank fits standard collet and end mill holders
• Single tool replaces separate drill and end mill in combination operations

Compatibility

Designed as a direct-fit replacement or standard addition for CNC machining centers and manual milling machines accepting 1/4 inch shank tooling with ER collet or end mill holder systems.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before loading or unloading the tool. Use a calibrated torque wrench on the collet nut to secure the shank without over-tightening. Verify runout after installation with a dial indicator before beginning the cut cycle.
