Harvey Tool 930932-C8 Square End Mill 1/2 in 3 Flute Carbide

Product Description

The HARVEY TOOL 930932-C8 is a solid carbide square end mill designed for precision milling operations in demanding metalworking and machining environments. With a 0.5-inch mill diameter, 0.75-inch length of cut, and a 42-degree variable helix geometry, this tool reduces chatter and improves surface finish across a wide range of materials. The TiB2 (Titanium Diboride) coating increases surface hardness and provides lubricity, extending tool life in abrasive cutting applications. It features three flutes and a right-hand cutting direction with right-hand flute orientation. This end mill is installed by machinists and CNC operators working in job shops, tool rooms, and production environments.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where variable helix geometry provides a performance advantage over standard fixed-helix tooling. The extended reach design, with a 2.5-inch reach length and 4-inch overall length, makes it appropriate for deeper-cavity or extended-reach milling scenarios. The 0.5-inch shank diameter fits standard ER collets, end mill holders, and shrink-fit toolholders commonly used on vertical and horizontal machining centers.

Key Features

• 42-degree variable helix reduces harmonic vibration and chatter during aggressive cuts
• TiB2 (Titanium Diboride) coating provides high surface hardness and low friction for improved tool life
• Solid carbide construction delivers rigidity and wear resistance
• Three-flute geometry balances chip evacuation and cutting edge strength
• Centercutting design allows plunge entry directly into the workpiece
• Extended reach with 2.5-inch reach length supports deeper cavity access

Compatibility

Designed as an OEM-style solid carbide square end mill replacement for use in standard 1/2-inch end mill holders, ER collet chucks, and shrink-fit toolholders on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into the toolholder to the recommended gauge length before tightening to avoid runout and premature wear. Ensure the machine spindle and toolholder are clean and free of chips or debris before mounting. Follow equipment manufacturer torque and clamping specifications for the toolholder type in use.
