Accupro 12185237 Square End Mill 3/8 Inch 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185237 is a solid carbide square end mill designed for precision milling operations in metal fabrication, toolroom work, and general machining. The double-end configuration provides two usable cutting ends, extending tool life before replacement. Built from micrograin solid carbide and finished with a TiCN coating, this end mill handles ferrous and non-ferrous materials with consistent dimensional control. The 40-degree spiral flute helix promotes efficient chip evacuation and reduces heat buildup during cutting. At 0.375 inches in diameter with a 0.5-inch length of cut, it is suited for slotting, profiling, and side milling in tight tolerances.

This end mill is used in CNC machining centers, manual mills, and tool-and-die applications across job shops and production facilities. The stub-length body provides rigidity for interrupted cuts and harder materials. Right-hand cut and right-hand flute geometry is standard for conventional spindle setups. The centercutting design allows plunge milling in addition to peripheral cutting, giving machinists flexibility in toolpath programming and manual operations.

Key Features

• Double-end design for extended usable tool life per unit
• Micrograin solid carbide substrate for wear resistance and dimensional stability
• TiCN finish increases surface hardness and reduces friction at the cutting edge
• 40-degree helix spiral flute promotes chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Stub length body increases rigidity and reduces deflection in demanding cuts

Compatibility

Designed as a direct-fit replacement or new-installation end mill for CNC and manual milling machines accepting a 3/8-inch straight shank in a standard collet, end mill holder, or milling chuck.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the spindle before changing tooling. Seat the shank to the full recommended grip depth in the holder and verify runout with a dial indicator before cutting. Follow machine manufacturer torque specifications for the collet nut or set screw — do not overtighten.
