Accupro 12183426 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 12183426 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 1-inch cutting diameter, a 2-inch length of cut, and a 0.045-inch corner radius that reduces stress concentrations at the base of milled features and extends tool life in high-cycle applications. With 4 right-hand spiral flutes and a bright uncoated finish, this single-end, centercutting tool handles both plunge and peripheral cuts. The micrograin carbide substrate provides hardness and wear resistance suited to demanding production environments. Machinists and CNC operators in job shops and manufacturing facilities are the primary users.

This end mill is well suited for finishing and semi-finishing passes in ferrous and non-ferrous materials where a radiused bottom corner is required. The long-length body with a 6-inch overall length and 1-inch shank diameter makes it appropriate for setups requiring additional reach into deep pockets or stepped features. It is a single-end tool intended for standard spindle holders and collet chucks compatible with a 1-inch shank.

Key Features

• 1-inch cutting diameter with a 0.045-inch corner radius for reduced corner chipping and improved surface finish
• 4 right-hand spiral flutes for efficient chip evacuation and smooth cutting action
• Solid micrograin carbide construction for hardness and wear resistance in demanding machining applications
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Bright uncoated finish suitable for a wide range of ferrous and non-ferrous materials
• Long-length configuration with 6-inch overall length for extended reach into deep pockets

Compatibility

Designed as an OEM-style replacement or direct substitute corner radius end mill for use in standard 1-inch shank collet chucks, end mill holders, and hydraulic toolholders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer specifications for runout and clamping torque. Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Confirm shank engagement depth meets the toolholder minimum grip length to prevent pull-out under cutting loads. Verify that the selected spindle speed and feed rate are appropriate for the workpiece material before initiating a cut.
