Accupro 95169901 Corner Radius End Mill 3/4 in 4-flute

Product Description

The ACCUPRO 95169901 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. It features a 3/4-inch mill diameter, a 7/8-inch length of cut, and a 3-inch overall length. The four-flute, right-hand spiral design is paired with an AlCrTiN coating that improves heat resistance and extends tool life in hard or abrasive materials. The micrograin carbide substrate adds edge strength and wear resistance. With a 0.120-inch corner radius and variable index geometry, this end mill reduces chatter and produces consistent, repeatable results. Licensed machinists and CNC operators rely on tools like this for finish milling, slotting, and profiling in steel, stainless, and hardened alloys.

The 95169901 is suited for use in vertical and horizontal machining centers running demanding ferrous and non-ferrous materials. The centercutting capability allows direct plunge entry, expanding application flexibility. The 3/4-inch straight-cylindrical shank fits standard ER and straight-bore toolholders. The Series HS designation indicates this tool is built for higher-speed, higher-feed programs where coating performance and edge geometry are critical to achieving target surface finish and dimensional accuracy.

Key Features

• AlCrTiN coating provides elevated heat and oxidation resistance for extended tool life in hard materials
• Micrograin solid carbide substrate delivers superior edge retention and rigidity
• Four-flute, right-hand spiral with variable index geometry reduces vibration and chatter
• Centercutting design enables direct plunge milling without a pre-drilled pilot hole
• 0.120-inch corner radius blends strength into the cutting edge and reduces corner chipping
• Straight-cylindrical shank for secure seating in ER collets and straight-bore toolholders

Compatibility

Designed as a direct-fit replacement or new-install tool for CNC machining centers and manual mills using 3/4-inch straight-bore or ER collet toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank to the full recommended grip depth in the toolholder and torque the collet nut per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut.
