Harvey Tool 46512-C3 Drill Mill 3/16 in 2 Flute Altin Carbide

Product Description

The HARVEY TOOL 46512-C3 is a solid carbide drill mill designed for machinists and toolroom professionals who need a single tool capable of drilling, chamfering, and end milling in one operation. With a 3/16 inch (0.1875 inch) mill diameter, a 90-degree point angle, and an AlTiN (aluminum titanium nitride) coating, this tool handles both ferrous and hardened materials with improved heat resistance and extended tool life. The 2-flute geometry provides efficient chip evacuation in tight pockets and shallow cavities. Overall length is 2 inches, keeping the tool rigid and reducing deflection in precision setups.

This drill mill is suited for CNC machining centers, knee mills, and manual milling machines in job shop, production, and toolroom environments. It is commonly used for spot drilling, through-hole drilling, countersinking, and light profiling in a single tool change. The 5/8 inch length of cut (0.6250 inch) accommodates typical shallow-depth operations in steel, stainless, cast iron, and aluminum. The 3/16 inch shank diameter matches the mill diameter, allowing direct mounting in standard collets without a step-down reduction.

Key Features

• 90-degree point angle supports accurate spot drilling and countersinking without a separate tool
• AlTiN coating provides high heat resistance for dry or minimal-lubrication cutting in ferrous materials
• Solid carbide construction delivers rigidity and wear resistance in demanding materials
• 2-flute design promotes chip clearance in blind holes and shallow pockets
• 3/16 inch shank matches mill diameter for direct collet mounting
• 2 inch overall length minimizes overhang and reduces deflection in close-tolerance work

Compatibility

Designed as a direct-mount drill mill for use in standard 3/16 inch collets on CNC machining centers and conventional milling machines. Consult tool geometry requirements for specific workpiece materials before use.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the shank in a clean, properly sized collet or end mill holder and torque the drawbar or nut per the machine manufacturer specification. Inspect the collet and taper for chips or wear before seating the tool. Follow shop safety protocols and machine guarding requirements whenever changing tooling with the spindle at rest and the machine in a locked-out state.
