Harvey Tool 934908-C3 Square End Mill 1/8 in 3 Flute

Product Description

The HARVEY TOOL 934908-C3 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 1/8 inch cutting diameter and a 3/16 inch length of cut, this tool delivers controlled material removal in tight geometries and shallow-to-moderate depth passes. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces at the tool tip. An AlTiN coating improves heat resistance and extends tool life in demanding dry or semi-dry cutting conditions. This end mill is single-end and center-cutting, making it suitable for both plunge and peripheral milling operations. It is installed and used by machinists and CNC programmers working in job shops, tool rooms, and production environments.

This end mill is suited for milling operations requiring fine detail work in small-diameter applications. The extended reach design, with a 7/8 inch reach length and 2-1/2 inch overall length, allows access to features with tighter clearance requirements. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle configurations. Typical materials include alloy steels, stainless steel, titanium, and hardened workpieces where AlTiN coating performance is an advantage.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating for elevated heat resistance and extended tool life in ferrous materials
• 3-flute geometry balances chip evacuation and surface finish quality
• 30-degree helix angle reduces cutting forces and supports smooth chip flow
• Center-cutting design allows direct plunge entry into workpiece material
• Extended reach with 7/8 inch reach length for access to deeper or restricted features

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 1/8 inch collets and tool holders used in CNC machining centers and manual mills with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the 1/8 inch shank fully and evenly in the collet or end mill holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear on a small-diameter carbide tool.
