Harvey Tool 15424 Drill Mill 3/8 in 4 Flute Solid Carbide

Product Description

The HARVEY TOOL 15424 is a solid carbide drill mill designed to perform both drilling and milling operations in a single tool. With a 3/8 inch diameter, a 4-flute geometry, and a 60-degree point angle, it handles center drilling, spot drilling, chamfering, and end milling without a tool change. The uncoated bright finish suits applications where coating interaction with the workpiece material is a concern. Machinists and CNC operators in tool shops, job shops, and production facilities rely on this style of drill mill to reduce setup time and consolidate operations on machining centers and CNC mills.

This drill mill is suited for use on vertical machining centers, CNC milling machines, and manual mills where multi-operation work is required. The 3/8 inch shank diameter fits standard ER collet chucks and end mill holders common in most shop environments. The 7/8 inch length of cut provides sufficient reach for shallow-to-moderate depth operations in ferrous and non-ferrous materials. The 2-1/2 inch overall length keeps the tool rigid and minimizes deflection during combined drill-and-mill passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• 60-degree point angle enables spot drilling, chamfering, and countersinking in addition to end milling
• 4-flute design provides good surface finish and chip clearance during milling passes
• 3/8 inch diameter and 3/8 inch shank diameter for straightforward fitment in standard collet and end mill holders
• Uncoated bright finish — compatible with a wide range of workpiece materials without coating concerns
• 7/8 inch length of cut and 2-1/2 inch overall length maintain tool rigidity and limit deflection

Compatibility

Designed as an OEM-style replacement or direct-fit drill mill for machining centers and CNC mills accepting 3/8 inch shank tooling in standard ER collet chucks, side-lock holders, or shrink-fit holders.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or removing tooling. Seat the shank fully in the collet or holder and torque the retention nut to the holder manufacturer specification. Verify tool length offset in the machine controller before cutting to avoid incorrect depth engagement.
