Harvey Tool 15305-C3 Drill Mill 4 Flute Solid Carbide Altin

Product Description

The HARVEY TOOL 15305-C3 is a solid carbide drill mill designed for combined drilling and milling operations in a single tool. With a 90-degree point angle, this tool enters material like a drill and transitions into side milling without a tool change, reducing cycle time on CNC and manual machining setups. The 0.0781-inch mill diameter and 0.25-inch length of cut make it well suited for small-bore and slot work. An AlTiN coating provides heat resistance and extended tool life in ferrous and hard materials. Machinists and tool-and-die professionals use this style of end mill to consolidate operations and reduce spindle downtime.

This drill mill is intended for use in precision machining environments including CNC machining centers, knee mills, and manual milling machines. The 1/8-inch shank diameter fits standard ER collets and end mill holders common in light-duty spindle setups. Typical applications include spotting, chamfering, drilling, and light peripheral milling in steel, stainless, aluminum, and other metals where the AlTiN finish provides thermal protection. The 90-degree point angle also makes this tool suitable for countersinking and deburring tasks without a separate tool change.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides high heat resistance and extends tool life in ferrous cutting
• 90-degree point angle enables drilling, spotting, chamfering, and countersinking
• 4-flute geometry supports both drilling entry and peripheral milling in a single pass
• 0.0781-inch mill diameter suits tight-tolerance and small-feature work

Compatibility

Designed for use in standard 1/8-inch end mill holders, ER collet chucks, and compatible tool holders on CNC machining centers and manual milling machines requiring a 90-degree drill mill configuration.

Installation Notes

Installation is performed by qualified machinists following standard tool-holding procedures. Ensure the spindle is fully stopped and power is off before loading or unloading the tool. Secure the shank fully within the collet or holder to the recommended engagement depth per the holder manufacturer's guidelines. Inspect the cutting edges for chips or wear before each use, as carbide tools can fail suddenly if run with damage.
