Accupro 95169771 Square End Mill 1/4 in 7 Flute Carbide

Product Description

The ACCUPRO 95169771 is a 7-flute solid carbide square end mill designed for high-performance milling in demanding machining applications. With a 1/4 inch cutting diameter and a 1/2 inch length of cut, this single-end mill features a 38-degree right-hand helix and an AlTiCrN coating that extends tool life under high-heat, high-speed conditions. The micrograin carbide substrate provides hardness and wear resistance needed for finishing and semi-finishing passes in ferrous and hardened materials. Machinists and CNC operators in job shop, tool-and-die, and production machining environments rely on this geometry for tight-tolerance work.

This end mill is suited for use in vertical and horizontal CNC machining centers, as well as manual mills where a 1/4 inch shank fits a standard collet or end mill holder. The 7-flute configuration increases chip load per revolution, making it well suited for finishing cuts at higher feed rates with reduced radial depth of cut. The 2.5 inch overall length accommodates most standard spindle setups without requiring extended-reach tooling. It is not center-cutting, so it is intended for peripheral milling rather than plunge entry.

Key Features

• 7-flute spiral flute design supports higher feed rates during finishing operations
• AlTiCrN coating provides thermal and oxidation resistance for extended tool life
• 38-degree right-hand helix promotes efficient chip evacuation and smooth surface finish
• Micrograin solid carbide substrate delivers hardness and dimensional stability
• 1/4 inch shank diameter fits standard collets and end mill holders
• Not center-cutting — designed for peripheral and slotting cuts, not direct plunge entry

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 1/4 inch shank end mill holder or collet. Part of the ACCUPRO HS Series solid carbide end mill line.

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 before changing tooling. Secure the shank to the manufacturer-specified minimum engagement depth in the collet or holder to prevent pullout under cutting loads. Verify runout with a dial indicator after installation before beginning a cut.
