Harvey Tool 896316-C8 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The HARVEY TOOL 896316-C8 is a solid carbide square end mill designed for precision milling operations across a range of metalworking and machining applications. It features a 1/4 inch cutter diameter, a 3/4 inch length of cut, and three flutes with a 42-degree variable helix angle. The downcut flute geometry reduces surface lifting and produces a clean top edge on the workpiece. A titanium diboride (TiB2) coating increases surface hardness and reduces friction at the cutting edge, extending tool life under demanding conditions. This is a single-end, right-hand cutting tool with a 1/4 inch shank diameter and a 2.5 inch overall length.

This end mill suits precision machining environments where surface finish and edge quality are critical. The downcut configuration is particularly effective when milling composites, laminates, or materials prone to delamination or fiber pullout. It is also used in aluminum and non-ferrous metal milling where a clean top-surface finish is required. Machinists and CNC operators in job shops, tool rooms, and production environments will find this tool well-suited for slotting, profiling, and finish passes in tight-tolerance work.

Key Features

• 1/4 inch cutter diameter with matching 1/4 inch shank for direct collet mounting
• 3/4 inch length of cut suitable for shallow-to-moderate depth slotting and profiling
• 3-flute, downcut geometry promotes clean top-surface finish and reduces workpiece lifting
• 42-degree variable helix angle reduces harmonic chatter during cutting
• TiB2 (Titanium Diboride) coating improves wear resistance and reduces built-up edge
• Solid carbide construction provides rigidity and dimensional stability at speed
• Single-end design; right-hand cutting direction

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1/4 inch collet or end mill holder. Compatible with ER-style collet chucks and standard 1/4 inch tool holders used in vertical and horizontal milling setups.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and locked before inserting or removing tooling. Seat the shank to the full recommended insertion depth in the collet or holder and torque the retention nut to the collet manufacturer's specification. Verify runout with a dial indicator after clamping before initiating a cut.
