Accupro 12185198 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12185198 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide stock, it carries a TiCN (titanium carbonitride) finish that extends tool life in ferrous and non-ferrous materials. The double-end configuration delivers two cutting ends per tool, maximizing value per unit. At 3/16 inch in diameter with a 40-degree helix angle and four spiral flutes, this end mill provides efficient chip evacuation and a clean, stable cut in tight geometries. The stub-length classification keeps deflection low during aggressive passes.

This end mill suits production machinists, tool-and-die shops, and precision job shops running vertical or horizontal CNC machining centers and manual knee mills. It is sized for fine-detail work, slotting, profiling, and peripheral milling in materials where a short, rigid cutting geometry reduces chatter. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling on most spindle setups. The centercutting design allows direct plunge entry, adding versatility in pocket-milling operations without a pre-drilled start hole.

Key Features

• Solid micrograin carbide construction for wear resistance and edge retention
• TiCN coating increases surface hardness and reduces heat buildup at the cutting edge
• Double-end design provides two usable cutting ends per tool
• 40-degree helix angle promotes smooth chip flow and reduced cutting forces
• Centercutting geometry allows direct plunge milling without a pilot hole
• Stub-length OAL minimizes overhang and deflection in precision cuts

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual mills accepting a 3/16 inch straight shank collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully within the collet or end mill holder to the manufacturer-specified engagement depth before tightening. Confirm spindle is fully stopped and machine is in an e-stop or locked-out state before changing tooling. Verify runout with a dial indicator after seating to confirm concentricity within acceptable tolerance for the application.
