Accupro 12185120 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12185120 is a solid carbide square end mill designed for precision milling operations in metal fabrication, tool-and-die, and general machining applications. The cutter measures 3/16 inches in diameter with a 1/2 inch length of cut and a 3/8 inch shank diameter, yielding a 3 inch overall length. Four spiral flutes with a 40-degree helix angle promote efficient chip evacuation and stable cutting at higher feed rates. A TiCN coating increases surface hardness and reduces friction at the cutting edge. The double-end configuration delivers two usable cutting ends per tool, extending service life. Micrograin carbide substrate supports tighter tolerances and improved edge retention compared to standard carbide grades.

This end mill suits vertical and horizontal milling machines as well as CNC machining centers handling ferrous and non-ferrous materials. The centercutting geometry allows plunge milling in addition to peripheral and slot milling operations. Right-hand cut and right-hand flute orientation match standard spindle rotation on conventional mills. The regular-length body keeps deflection low in close-tolerance profiling, contouring, and slotting work where a 3/16 inch diameter tool is specified.

Key Features

• Solid micrograin carbide construction for edge retention and dimensional stability
• TiCN coating reduces friction and extends tool life in ferrous materials
• 40-degree helix angle promotes aggressive chip evacuation and smooth cutting action
• Double-end design provides two cutting ends per tool
• Centercutting capability allows direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute for use with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling selection for milling machines and CNC machining centers accepting a 3/8 inch straight shank with a 3/16 inch cutter diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the 3/8 inch shank in a collet or end mill holder rated for the intended spindle speed before beginning any operation. Confirm the tool is fully seated and clamped to manufacturer torque specifications for the holder type before powering the spindle. Inspect the cutting edges for chips or coating damage before each use and replace the tool if wear exceeds acceptable limits.
