Harvey Tool 988148-C3 Drill Mill 3/4in 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 988148-C3 is a solid carbide drill mill designed to perform both drilling and milling operations in a single tool, reducing setup time and tool changes on the spindle. Built with 4 flutes and a 120-degree point angle, it handles center drilling, chamfering, spot drilling, and peripheral milling across a range of workpiece materials. The AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. With a 3/4 inch cutting diameter and 1-1/2 inch length of cut, this tool is suited for moderate-depth milling passes and through-hole work on CNC machining centers.

This drill mill is used in precision machining environments including job shops, aerospace, mold and die, and general manufacturing. It installs in standard 3/4 inch tool holders, collet chucks, or end mill holders on vertical and horizontal CNC machining centers. The combination geometry makes it a practical choice when a single tool must handle multiple operations in a tight program or when minimizing tool changes is a priority on high-mix, low-volume work.

Key Features

• Solid carbide construction provides rigidity and dimensional stability under cutting loads
• AlTiN coating delivers high-temperature oxidation resistance for dry or minimal-lubrication cutting
• 120-degree point angle suited for spot drilling, chamfering, and transition into milling passes
• 4-flute geometry balances chip evacuation with surface finish on peripheral cuts
• Matched shank and cutting diameter at 3/4 inch allows direct clamping without step-down adapters
• 4 inch overall length provides clearance for typical fixture and workholding setups

Compatibility

Designed for use in standard 3/4 inch bore end mill holders, collet chucks, and hydraulic tool holders on CNC machining centers. Verify spindle taper and holder bore before installation.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the spindle before loading or removing the tool from the holder. Ensure the shank is fully seated to the minimum clamp depth recommended by the holder manufacturer to prevent pullout under cutting loads. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut before running the program.
