Accupro 12181941 Square End Mill 7/32 in 3 Flute Carbide

Product Description

The ACCUPRO 12181941 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering-grade materials. Built from micrograin carbide, it delivers the hardness and edge retention needed for consistent performance in production and job-shop environments. The 3-flute, spiral-flute geometry with a 40-degree helix angle balances chip evacuation with surface finish quality. At 7/32 inch (0.2188 inch) diameter with a 5/8 inch length of cut, this tool handles slot milling, profiling, and peripheral cutting in tight tolerances. Installation and use require a milling machine or machining center equipped with a compatible 1/4 inch collet or tool holder.

This end mill is suited for CNC machining centers and conventional knee mills in both production and maintenance-repair-operations (MRO) settings. The centercutting design allows plunge entry directly into the workpiece, expanding its use in interpolation and ramping applications. The right-hand cut and right-hand flute configuration is standard for conventional spindle-direction setups. With a 2-1/2 inch overall length and regular length classification, it fits standard tooling setups without extended-reach clearance concerns.

Key Features

• Micrograin solid carbide construction for superior edge retention and wear resistance
• 3-flute spiral flute design with 40-degree helix angle for balanced chip clearance and finish quality
• Centercutting capability allows direct plunge entry into the workpiece
• Right-hand cut, right-hand flute configuration for standard spindle setups
• Uncoated finish suitable for applications where coating is not required or where regrinding is anticipated
• Mill diameter tolerance of +0.000 / -0.002 inch for consistent, accurate cuts

Compatibility

Designed for use in any milling machine or machining center with a 1/4 inch collet, end mill holder, or equivalent toolholding system accepting a 0.2500 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked before changing tooling. Verify the collet or tool holder is clean and free of debris before seating the shank, and confirm runout is within acceptable limits after clamping. Follow applicable shop safety procedures and machine manufacturer guidelines for tool change operations.
