Harvey Tool 26524-C3 Drill Mill 3/8in 4 Flute 82 Deg Altin

Product Description

The HARVEY TOOL 26524-C3 is a solid carbide drill mill designed to perform both drilling and milling operations in a single tool. With a 3/8 inch diameter and a 4-flute geometry, it handles center drilling, chamfering, and end milling in ferrous and non-ferrous materials. The 82-degree point angle makes it well-suited for spotting and countersinking to common fastener angles. An AlTiN coating provides elevated heat resistance and surface hardness, extending tool life in demanding cutting conditions. This tool is sized for use in vertical machining centers, knee mills, and CNC routers where multi-function tooling reduces changeovers and improves cycle time.

The 26524-C3 fits standard applications in job shops, production machining, and toolroom environments. It is used in setups requiring a single tool to drill, spot, chamfer, or profile in steel, stainless, cast iron, and similar materials. The 7/8 inch length of cut and 2-1/2 inch overall length suit shallow-to-medium depth applications in workpiece materials where AlTiN coatings perform best under dry or minimal-coolant conditions. Machinists and CNC operators working with tight tolerances and multi-step operations benefit from consolidating operations into one tool pass.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 4-flute design provides efficient chip evacuation and improved surface finish
• 82-degree point angle for spotting and countersinking to standard fastener geometry
• AlTiN coating for high-temperature resistance and extended tool life in dry cutting
• Matched shank and cutting diameter at 3/8 inch for direct collet or chuck mounting
• Combines drilling and milling capability to reduce tool changes in multi-step setups

Compatibility

Designed as a direct-fit replacement or new-install drill mill for CNC machining centers, knee mills, and manual mills using standard 3/8 inch collets or end mill holders.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Secure the shank in a properly sized collet or end mill holder and verify runout before cutting. Power down and lock out the spindle before changing or inspecting tooling. Follow machine tool manufacturer guidelines for speed and feed settings appropriate to the workpiece material and coating type.
