Accupro 95168366 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 95168366 is a solid carbide square end mill designed for high-performance milling in ferrous and hardened materials. With a 3/8 inch cutting diameter, a 1 inch length of cut, and a 60-degree helix angle, this tool delivers aggressive chip evacuation and reduced cutting forces in demanding applications. The AlTiN coating provides excellent heat resistance and wear resistance, extending tool life in dry or high-speed machining conditions. The micrograin carbide substrate supports sharp edge retention under continuous load. This end mill is used by machinists and tool-and-die professionals in CNC milling centers and manual knee mills alike.

This end mill suits a wide range of material removal operations including slotting, profiling, and peripheral milling. The 3-flute geometry balances chip clearance and cutting edge count, making it effective in both aluminum and harder ferrous alloys. The right-hand cutting and right-hand spiral flute direction is standard for conventional CNC spindle rotation. It is a single-end, regular-length configuration with no chipbreaker, suited for general-purpose and finish milling passes where a clean square shoulder is required.

Key Features

• 60-degree helix angle promotes efficient chip evacuation and reduces heat buildup at the cutting edge
• AlTiN coating delivers superior thermal resistance and extended tool life in dry or high-speed cuts
• Micrograin solid carbide substrate provides rigidity and sharp edge retention
• 3-flute design balances chip clearance with cutting performance across a range of materials
• Centercutting geometry allows plunge entry as well as standard peripheral and slot milling
• Right-hand cut and right-hand spiral for compatibility with standard CNC spindle direction

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 3/8 inch straight-shank collet chucks and end mill holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully into the collet or tool holder to the recommended gauge depth and torque the retention hardware per the tool holder manufacturer specifications. Verify runout with a dial indicator before production cutting.
