Accupro 12182485 Square End Mill 19/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182485 is a single-end square end mill designed for precision milling operations in ferrous and non-ferrous metals. Built from micrograin solid carbide, it delivers rigidity and wear resistance that high-speed steel tooling cannot match at elevated cutting speeds. The 19/64 inch (0.2969 inch) cutting diameter pairs with a 4-flute spiral configuration and a 40-degree right-hand helix to promote efficient chip evacuation and smooth surface finishes. A TiCN (Titanium Carbonitride) coating adds surface hardness and reduces built-up edge, extending tool life in demanding applications. This end mill is centercutting, allowing plunge cuts without a pre-drilled entry point.

This tool is suited for slot milling, profiling, and pocketing in CNC machining centers and manual knee mills. The 3/4 inch length of cut, 5/16 inch shank diameter, and 2-1/2 inch overall length make it appropriate for shallow-to-moderate depth passes in tooling, die, and general production environments. Machinists and toolroom technicians working with ferrous alloys, stainless, and hardened materials will find the TiCN coating and micrograin carbide substrate well matched to those workpiece materials.

Key Features

• Micrograin solid carbide substrate for rigidity and extended tool life
• TiCN coating reduces friction and resists built-up edge in ferrous and stainless materials
• 40-degree right-hand helix promotes chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge entry without a pilot hole
• 4-flute spiral configuration balances material removal rate with finish quality
• Tight mill diameter tolerance of +0.000 / -0.002 inch for accurate slot and profile dimensions

Compatibility

Designed for use in standard 5/16 inch collets and end mill holders on CNC machining centers, vertical mills, and compatible manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the end mill from its holder. Seat the shank fully into the collet or holder to the depth recommended by the toolholder manufacturer, leaving no more shank exposed than necessary to reach cutting depth. Verify runout with a dial indicator after tightening to confirm proper seating before beginning a cut.
