Harvey Tool 995808 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The HARVEY TOOL 995808 is a 4-flute solid carbide square end mill engineered for high-precision milling in demanding materials. With a 1/8 inch cutting diameter and a 3/8 inch length of cut, this tool is built for slotting, profiling, and finishing passes where tight tolerances are required. The CVD diamond coating delivers exceptional hardness and wear resistance, making it well suited for abrasive and non-ferrous materials. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces, while the centercutting geometry allows direct plunging into the workpiece.

This end mill is used in CNC machining centers and manual mills for precision work in composites, graphite, ceramics, nonferrous alloys, and other abrasive materials where a diamond-coated carbide tool provides clear advantages over uncoated or TiN-coated alternatives. At 1-1/2 inches overall length with a 1/8 inch shank, it fits standard collets and tool holders in both vertical and horizontal setups. Right-hand cut and right-hand flute configuration aligns with standard spindle rotation on most machining platforms.

Key Features

• CVD diamond coating for extreme wear resistance in abrasive and nonferrous materials
• Solid carbide construction for rigidity and dimensional stability
• 4-flute design improves surface finish and material removal rate
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting geometry enables direct plunge cuts
• Right-hand cut, right-hand flute for compatibility with standard CNC spindle rotation

Compatibility

Designed as a direct-fit replacement for 1/8 inch shank tooling in standard ER and TG collet systems used on CNC machining centers and manual milling machines requiring a 4-flute square end mill with a CVD diamond finish.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Seat the shank fully in the collet to the recommended grip length and torque the collet nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning any cutting operation, as excessive runout accelerates tool wear and degrades surface finish.
