Accupro 95168821 Corner Radius End Mill 3/4in 5 Flute

Product Description

The ACCUPRO 95168821 is a solid carbide corner radius end mill designed for high-performance milling in ferrous and hardened materials. It features a 3/4 inch cutting diameter, a 0.0900 inch corner radius, and five flutes with a right-hand spiral cut. The AlTiN coating provides thermal resistance and extended tool life in dry or high-speed machining conditions. At 3 inches overall length with a 1 inch length of cut, this is a stub-length tool built for rigidity and minimal deflection. Machinists and tool-and-die professionals use this end mill in CNC milling centers where corner radius geometry is required to reduce stress concentrations in part features.

This end mill suits precision milling applications in job shops, production machining environments, and toolroom work. The centercutting design allows plunge entry, adding versatility for interpolated pocketing and slotting operations. The right-hand cutting direction and right-hand flute direction are standard for conventional and climb milling on CNC vertical and horizontal machining centers. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of workpiece materials including alloy steels and stainless.

Key Features

• 0.0900 inch corner radius reduces stress risers and improves surface finish at feature edges
• AlTiN coating provides oxidation resistance and hardness retention at elevated cutting temperatures
• Five-flute geometry increases feed rate capability compared to standard four-flute end mills
• Micrograin solid carbide substrate delivers rigidity and wear resistance
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Stub-length construction maximizes rigidity and reduces deflection in tight setups

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC milling centers accepting a 3/4 inch shank diameter end mill with right-hand cutting direction.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The tool should be seated in a clean, properly sized collet or end mill holder and torqued to the holder manufacturer's specification. Verify runout with a dial indicator before production cutting. Always confirm spindle direction and feed-rate programming match the right-hand cutting geometry of this tool before initiating a cut.
