Accupro 12182650 Square End Mill 11/16 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12182650 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 11/16 inch (0.6875 inch) cutting diameter, a 1-1/2 inch length of cut, and a 3/4 inch shank diameter with an overall length of 4 inches. The micrograin carbide substrate provides the hardness and wear resistance needed for demanding cutting applications. A TiCN (Titanium Carbonitride) finish reduces friction and extends tool life. This tool is intended for use by machinists and CNC operators in production and job shop environments.

This end mill is suited for slotting, profiling, and peripheral milling on machining centers and CNC mills. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces, making it effective for both roughing and finishing passes on steel, stainless steel, cast iron, and high-temperature alloys. The centercutting geometry allows for direct plunge entry into a workpiece without a pre-drilled hole. Right-hand cut and right-hand flute configuration match standard spindle rotation on most vertical machining centers.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• TiCN finish reduces friction and increases wear resistance in abrasive materials
• 40-degree spiral helix promotes efficient chip evacuation and smoother cuts
• Centercutting design allows direct plunge milling without pilot drilling
• 4 flutes provide a balance of chip clearance and cutting edge engagement
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit in tight-tolerance work

Compatibility

Designed as a standard-shank replacement end mill for use in 3/4 inch collets, end mill holders, or hydraulic tool holders on CNC vertical machining centers and manual knee mills requiring a regular-length, 4-flute square end mill with a 11/16 inch cutting diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an E-stop or locked-out state before loading or unloading the tool. Seat the shank to the minimum recommended engagement depth in the holder to prevent pullout under cutting load. Verify runout with a dial indicator after clamping, and confirm feed and speed parameters are appropriate for the workpiece material before initiating a cut.
