Accupro 95169889 Corner Radius End Mill 3/4 in 5 Flute Carbide

Product Description

The ACCUPRO 95169889 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. With a 3/4 inch diameter, a 1-5/8 inch length of cut, and a 0.190 inch corner radius, it handles contouring, profiling, and finishing passes where edge integrity and surface finish matter. The AlCrTiN coating provides thermal resistance and extended tool life in ferrous and hardened materials. A 38-degree variable index helix and five flutes promote chip evacuation and reduce chatter, making this tool well suited for aggressive material removal rates in CNC machining centers.

This end mill fits standard CNC vertical and horizontal machining center applications requiring a 3/4 inch shank. It is single-end, right-hand cutting, and centercutting, allowing plunge entry in addition to peripheral and slot milling. The 4 inch overall length provides clearance for moderate-depth workpiece features. Typical users include machinists and tooling specialists working in job shops, aerospace, mold and die, and general metalworking environments. The micrograin carbide substrate supports use in steels, stainless, and cast iron at elevated cutting speeds.

Key Features

• Solid micrograin carbide substrate for rigidity and wear resistance in ferrous materials
• AlCrTiN coating enhances thermal stability and extends tool life in high-speed applications
• Five flutes with variable index reduce harmonic vibration and improve surface finish
• 0.190 inch corner radius protects the cutting edge and reduces stress concentrations in the workpiece
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Right-hand spiral flutes with right-hand cutting direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers accepting a 3/4 inch straight shank end mill in Series HS toolholders and standard ER or side-lock collet chucks.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in an estop or lockout-tagout state before loading or unloading the tool. Seat the shank to the full recommended grip depth in the toolholder to minimize runout and prevent pullout during cutting. Verify runout with a dial indicator before beginning the first cut, and inspect the cutting edges for chipping after initial passes in hard or abrasive materials.
