Accupro 12181293 Corner Radius End Mill 3/16in 2 Flute Carbide

Product Description

The ACCUPRO 12181293 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. Built with a 3/16 inch diameter and a 0.02 inch corner radius, it produces a consistent, blended edge profile that reduces stress concentrations in machined pockets, slots, and contours. The single-end, center-cutting design allows plunge entry as well as standard peripheral cutting. With a micrograin carbide substrate and a bright uncoated finish, this tool is suited for applications where coolant is used or where coating-free contact is required. Machinists and tool-and-die shops running 3-axis and 5-axis CNC mills are the primary users.

This end mill is used in general machining environments where a small-diameter corner radius tool is needed for finishing passes, slot milling, and contour work. The 5/8 inch length of cut provides adequate reach for shallow-to-mid-depth pockets without sacrificing rigidity. The right-hand cutting direction and right-hand spiral flute geometry make it compatible with standard CNC machining center spindle rotation. It is a single-quantity, single-end tool packaged for individual use in production or maintenance machining settings.

Key Features

• 0.02 inch corner radius reduces edge chipping and stress risers in finished workpieces
• Solid micrograin carbide construction provides rigidity and wear resistance
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Bright uncoated finish compatible with a wide range of cutting fluids and base materials
• 2-flute configuration promotes chip evacuation in softer materials and confined pockets
• 40-degree helix angle improves surface finish and reduces cutting forces

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 3/16 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists following standard CNC tooling procedures. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing tooling. Use a calibrated collet or end mill holder sized for a 3/16 inch shank and verify runout with a dial indicator before production cuts. Do not exceed the manufacturer-recommended feeds and speeds for the workpiece material and cutting depth.
