Accupro 95169928 Corner Radius End Mill 3/4 in 5 Flute

Product Description

The ACCUPRO 95169928 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Built on the HS Series platform, this single-end tool features a 3/4 inch diameter, a 1 inch length of cut, and a 0.090 inch corner radius that reduces stress concentrations at the bottom of milled pockets and slots. The AlCrTiN coating delivers high-temperature and oxidation resistance, extending tool life in demanding cutting conditions. With 5 flutes, a variable index design, and a 38-degree helix, it balances chip evacuation with surface finish quality. Micrograin carbide construction provides hardness and edge retention. Centercutting geometry allows plunge entry.

This end mill is suited for milling hardened steels, alloy steels, stainless steels, and similar ferrous materials in production and job shop environments. It is a fit for CNC machining centers and manual knee mills wherever a corner radius profile is required to meet drawing callouts or reduce corner stress in pocketing, contouring, and slotting operations. The straight cylindrical shank mounts directly into standard ER collets, Weldon holders, and hydraulic chucks with a 3/4 inch bore.

Key Features

• Solid micrograin carbide substrate for hardness and edge retention at elevated cutting speeds
• AlCrTiN coating provides oxidation and heat resistance, extending tool life in dry and semi-dry cutting
• 0.090 inch corner radius reduces workpiece stress concentrations and improves pocket floor blending
• 5-flute, 38-degree helix variable index design balances chip load, reduces chatter, and improves surface finish
• Centercutting construction permits direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute spiral for use on standard CNC and manual milling spindles

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills requiring a 3/4 inch straight cylindrical shank corner radius end mill. Compatible with standard ER, Weldon, and hydraulic toolholders bored to 3/4 inch.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Confirm holder bore diameter matches the 3/4 inch shank and tighten to the toolholder manufacturer's specified torque using calibrated tooling. Verify runout with a dial indicator after seating to maintain edge life and dimensional accuracy.
