Accupro 12182247 Square End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12182247 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 3/8-inch cutting diameter and a 1-3/4-inch length of cut, it delivers consistent material removal across a range of ferrous and non-ferrous workpieces. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Built from micrograin solid carbide, this tool offers rigidity and wear resistance suited to demanding production environments. Installed by machinists and tool-and-die professionals, it is a single-end, uncoated tool with right-hand cut and right-hand flute geometry.

This end mill is well suited for slotting, profiling, and peripheral milling applications in CNC machining centers and manual knee mills. The extra-long 4-inch overall length provides extended reach for deeper cavities and stepped features where standard-length tooling cannot access. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled hole, expanding its versatility in multi-operation setups. Typical applications include mold work, fixture building, and general precision part production.

Key Features

• Micrograin solid carbide construction for improved hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting capable — supports direct plunge entry into material
• Extra-long 4-inch OAL for extended reach into deep pockets and cavities
• Spiral flute, right-hand cut and right-hand flute configuration
• Uncoated finish suitable for use with cutting fluids in a variety of materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill compatible with standard 3/8-inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the milling machine spindle is fully stopped and locked before inserting or removing the end mill. Seat the shank fully and evenly in a properly sized collet or end mill holder and torque the retention hardware to the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing cuts to protect both the tool and the workpiece.
