Accupro 12182759 Corner Radius End Mill 3/16in 4 Flute Carbide

Product Description

The ACCUPRO 12182759 is a solid carbide corner radius end mill designed for precision milling operations in metal and composite materials. It features a 3/16 inch cutting diameter with a 0.045 inch corner radius, producing a controlled fillet at the base of milled features and reducing stress concentrations in the workpiece. The 3/8 inch length of cut and stub-length geometry provide rigidity in tight-clearance setups. With four spiral flutes and a right-hand cutting direction, it delivers efficient chip evacuation and smooth surface finishes. This tool is installed and operated by machinists and tooling professionals on CNC machining centers and manual mills.

This end mill is suited for finishing and semi-finishing passes in ferrous and non-ferrous metals where a radiused corner profile is required. The bright uncoated finish makes it appropriate for use in materials where coating adhesion is not critical or where re-sharpening is anticipated. The stub-length body keeps deflection low in short-reach applications. Its centercutting capability allows direct plunge entry into the workpiece without a pre-drilled pilot hole, giving operators flexibility in toolpath programming.

Key Features

• 0.045 inch corner radius produces consistent fillets and reduces stress risers at milled corners
• Solid micrograin carbide construction provides hardness and wear resistance across a range of materials
• Four spiral flutes with right-hand flute direction for efficient chip removal and surface finish quality
• Centercutting design permits direct plunge milling without a starter hole
• Stub-length body minimizes tool deflection and improves rigidity in short-reach setups
• Bright uncoated finish suitable for general-purpose machining and re-sharpenable applications

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 3/16 inch collets or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and the tool holder is clean and free of chips before seating the tool. Confirm runout with a dial indicator after clamping to the specified shank diameter tolerance range. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting feeds, speeds, and depth of cut.
