Accupro 12185153 Square End Mill 3/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12185153 is a solid carbide square end mill designed for high-precision milling of tight-tolerance features in metalworking and machining applications. Built from micrograin carbide with a titanium carbonitride (TiCN) finish, this double-end tool delivers extended tool life and wear resistance in ferrous and non-ferrous materials. The 3/64 inch cutting diameter, 30-degree helix angle, and 4-flute spiral geometry promote efficient chip evacuation and smooth surface finishes in confined or detailed workspaces. Centercutting capability allows direct plunge entry without a pre-drilled hole.

This end mill is suited for precision slot milling, profiling, and finishing passes where small feature geometry is required. The stub length configuration and 1/8 inch shank diameter make it compatible with standard collet chucks and small-bore tool holders on CNC machining centers and manual mills. Its right-hand cut and right-hand flute orientation match standard spindle rotation. Applications include die and mold work, electronic component machining, and detailed fixture fabrication.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention in precision work
• TiCN coating improves wear resistance and reduces friction at the cutting edge
• Double-end design provides two usable cutting ends per tool
• 30-degree helix angle with 4-flute spiral geometry for efficient chip flow
• Centercutting — capable of plunge cutting without a pilot hole
• Stub length overall at 1.5 inches OAL for improved rigidity in short-reach setups

Compatibility

Designed for use in standard 1/8 inch collet chucks and small-bore end mill holders on CNC machining centers and manual knee mills. The 1/8 inch shank diameter fits common ER11 and ER16 collet sets.

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 or in a safe-lock state before changing tooling. Seat the shank fully and evenly in the collet or chuck before tightening to the tool holder manufacturer's specified torque range. Inspect the cutting edges for chips or damage before each use, as carbide end mills at this diameter are susceptible to breakage under lateral shock loads.
