Accupro 12182353 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 12182353 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 1 inch cutting diameter, a 1.75 inch length of cut, and a 0.06 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in shoulder and slot milling. The 4-flute, right-hand spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and stable cutting at higher feed rates. The bright uncoated finish makes it well suited for use in non-ferrous metals and applications where coating is not required or where re-sharpening is anticipated.

This end mill is used in CNC machining centers and manual mills across job shops, production facilities, and tool rooms. It is a single-end, centercutting tool, meaning it can be plunged directly into workpiece material as well as used for conventional peripheral and slot milling. The 1 inch shank diameter provides a secure fit in standard ER or CAT toolholders sized for 1 inch shanks. It is appropriate for finish and semi-finish milling of ferrous and non-ferrous materials where a controlled corner radius profile is required.

Key Features

• 1 inch mill diameter with tight tolerance of +0.000000 to -0.002500 inches for accurate sizing
• 0.06 inch corner radius reduces edge chipping and improves surface finish at workpiece corners
• 40-degree helix angle with right-hand flute direction supports smooth chip flow and reduced cutting forces
• Solid micrograin carbide construction provides hardness and wear resistance across a range of materials
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Bright uncoated finish suitable for non-ferrous metals and applications requiring re-sharpening

Compatibility

Designed as an OEM-style solid carbide corner radius end mill compatible with standard 1 inch shank toolholding systems on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or placed in an e-stop state before changing tooling. The shank should be cleaned and inspected before seating in the holder; shank diameter tolerance is -0.0001 to -0.0004 inches. Follow the machine tool manufacturer and toolholder manufacturer specifications for minimum shank engagement depth and clamping torque.
