Harvey Tool 888447-C3 Square End Mill 3/64 in 3 Flute

Product Description

The HARVEY TOOL 888447-C3 is a solid carbide square end mill designed for precision milling in tight-tolerance machining applications. With a 3/64 inch (0.0470 inch) cutting diameter and a 3/16 inch (0.187 inch) length of cut, this tool is built for small-feature work where dimensional accuracy is critical. The three-flute geometry balances chip evacuation with surface finish quality, and the 30-degree right-hand helix promotes smooth cutting action. An AlTiN coating provides heat resistance and extends tool life in ferrous and hardened materials. Machinists and tool-and-die professionals working on CNC milling centers will find this end mill suited to fine detail work.

This end mill is well suited to applications requiring small-diameter cutting in steel, stainless steel, hardened materials, and similar substrates where AlTiN coatings provide a thermal and wear advantage. The 1/8 inch shank diameter fits standard collet systems, and the 2-1/2 inch overall length gives enough reach for most shallow-pocket and contour-milling operations. Single-end configuration means the tool is replaced rather than flipped when worn, keeping setup times predictable.

Key Features

• 3/64 inch (0.0470 inch) cutting diameter for small-feature and fine-detail milling
• 3-flute design balances chip flow and finish quality in harder materials
• 30-degree right-hand helix for smooth cutting and reduced chatter
• AlTiN coating improves heat resistance and extends tool life in ferrous alloys
• Centercutting geometry allows plunge entry without pre-drilling
• Solid carbide construction delivers rigidity and dimensional stability

Compatibility

Designed as an OEM-style replacement-grade solid carbide square end mill suitable for CNC machining centers and manual mills equipped with 1/8 inch collet or collet chuck systems.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling and collet systems. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut according to the collet manufacturer specification. Verify runout with a dial indicator before initiating a cutting pass on close-tolerance features.
