Harvey Tool 33302-C3 Square End Mill 7/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 33302-C3 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 7/64 inch (0.109 inch) cutting diameter and a 0.164 inch length of cut, this tool is built for tight-tolerance work in small-diameter applications. The three-flute geometry balances chip evacuation with cutting efficiency, and the AlTiN coating improves heat resistance and tool life in ferrous and hardened materials. At 2.5 inches overall length with a 1/8 inch shank diameter, it is sized for use in standard collet chucks and milling machines.

This end mill is suited for slot milling, profiling, and finishing passes in steel, stainless steel, cast iron, and similar hard materials where heat generation and tool wear are primary concerns. The extended reach design, with a 0.57 inch reach length, allows access to recessed features and stepped geometry. It is centercutting, enabling plunge entry, and operates with right-hand cutting and right-hand flute direction. Machinists in job shops, tool rooms, and production environments working with small-bore or fine-detail components will find this tool appropriate for their applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for extended tool life and performance at elevated cutting temperatures
• 3-flute design balances chip clearance and surface finish quality
• Centercutting geometry allows direct plunge milling without pre-drilled entry
• Extended reach with 0.57 inch reach length for access to recessed features
• 30-degree helix angle promotes smooth cutting action and reduced cutting forces

Compatibility

Designed as a direct-fit replacement for standard 1/8 inch shank collet holders and milling chucks used in CNC machining centers and manual milling machines requiring a 7/64 inch diameter square end mill.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1/8 inch shank fully into the collet or tool holder and torque the collet nut to the tool holder specification. Verify runout with a dial indicator before commencing cutting operations, as excessive runout will accelerate wear on a small-diameter tool of this type.
