Accupro 12182209 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12182209 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin carbide stock and finished with a titanium carbonitride (TiCN) coating, this tool delivers extended wear resistance in demanding cutting environments. The 3/16 inch cutting diameter pairs with a 3/4 inch length of cut and a 40-degree helix angle across three spiral flutes, promoting efficient chip evacuation and reduced cutting forces. At 2-1/2 inches overall length, it falls into the long-length category, giving machinists added reach without sacrificing rigidity. Centercutting geometry allows for direct plunge entry into workpieces.

This end mill is suited for precision slot milling, profiling, and plunge cutting in CNC machining centers and manual milling machines. The long-length configuration is particularly useful when clearance depth is required beyond what a standard-length tool can reach. The right-hand cut and right-hand flute orientation follow conventional milling machine spindle direction. The shank diameter matches the cutting diameter at 3/16 inch, making it compatible with standard collets and end mill holders in that size range. Typical users include CNC machinists, tool-and-die professionals, and precision machine shops.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• TiCN coating improves surface hardness and wear resistance over uncoated carbide
• 40-degree helix angle on spiral flutes promotes smooth chip flow
• Centercutting design enables direct plunge entry without pre-drilling
• Long-length category provides extended reach for deeper features
• Right-hand cut and right-hand flute for standard spindle operation

Compatibility

Designed for use with standard 3/16 inch collets and end mill holders in CNC machining centers and manual knee mills. No specific machine or system compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist with the machine spindle fully stopped and locked out before tool changes. Seat the shank fully into the collet or holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut. Consult the machine tool manual and applicable shop safety standards before operation.
