Accupro 12183134 Corner Radius End Mill 3/4 in 4 Flutes

Product Description

The ACCUPRO 12183134 is a solid carbide corner radius end mill designed for precision milling operations in metal and hard-material applications. The tool features a 3/4 inch cutting diameter with a 1/8 inch (0.1250 inch) corner radius, a 2-1/4 inch length of cut, and a 5 inch overall length. The 4-flute, right-hand spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and surface finish quality. Bright/uncoated finish makes it suitable for use in non-ferrous metals and materials where coating buildup is a concern. Installed by machinists and CNC operators in job shop, tool room, and production environments.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where a long-reach, single-end corner radius tool is required. The centercutting design allows plunge entry as well as conventional peripheral and slot milling. The 3/4 inch shank diameter fits standard ER and side-lock toolholders. Typical applications include profile milling, slotting, and contouring operations where a radiused corner is needed to reduce stress concentration in machined pockets and slots.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• 1/8 inch corner radius reduces stress risers in milled pockets and slots
• 4-flute right-hand spiral with 40-degree helix for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Bright/uncoated finish suited for non-ferrous and general-purpose milling
• Long flute length of 2-1/4 inches supports deep pocket and wall milling

Compatibility

Designed as an OEM-style replacement and standard fitment for 3/4 inch shank toolholders used in CNC vertical machining centers and manual mills requiring a single-end corner radius end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully in the toolholder and verify runout with a dial indicator before beginning a cut. Follow machine tool manufacturer torque specifications for collet nuts and side-lock set screws.
