Harvey Tool 14364-A Drill Mill 1 in 4 Flute 90 Pt Cobalt

Product Description

The HARVEY TOOL 14364-A is a cobalt drill mill designed to perform both drilling and end milling operations in a single tool. With a 1-inch mill diameter, a 90-degree point angle, and 4 flutes, this tool handles center drilling, spotting, chamfering, and peripheral milling without a tool change. The uncoated cobalt construction provides good heat resistance and toughness, making it suitable for cutting ferrous and difficult-to-machine materials. A 3/4-inch shank diameter and 4-1/8-inch overall length give it solid rigidity in standard milling chucks and collet holders.

This drill mill is used in CNC machining centers and manual knee mills where machinists need to combine drilling and milling operations on a single setup. The 1-7/8-inch length of cut accommodates moderate-depth pocketing and slotting. The 90-degree point geometry is well suited for spotting, countersinking, and producing chamfers on through-holes and blind features. It is typically installed by machining professionals working in job shops, toolrooms, and production environments cutting steel, stainless, and alloy materials.

Key Features

• Cobalt construction for improved heat resistance and durability in ferrous and tough alloy materials
• 90-degree point angle enables spotting, chamfering, and countersinking without a separate tool
• 4-flute design supports both drilling and peripheral end milling in one operation
• 1-7/8-inch length of cut handles moderate-depth slots, pockets, and chamfers
• Uncoated finish allows easy resharpening and is compatible with oil-based cutting fluids
• 3/4-inch shank diameter fits standard ER collets, side-lock holders, and hydraulic chucks

Compatibility

Designed as an OEM-style replacement or direct-fit drill mill for CNC machining centers and manual mills accepting a 3/4-inch shank diameter toolholder.

Installation Notes

This tool is installed by machinists in collet chucks, end mill holders, or hydraulic toolholders rated for 3/4-inch shanks. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Verify spindle speed and feed rates against material-specific cutting data before operation. Follow all applicable machine guarding and lockout/tagout procedures when changing tools.
