Accupro 12181335 Corner Radius End Mill 1/4 in 2 Flute Carbide

Product Description

The ACCUPRO 12181335 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 1/4 inch diameter cutting edge with a 0.06 inch corner radius, a 3/4 inch length of cut, and a 2-1/2 inch overall length. The two-flute, right-hand spiral geometry and centercutting capability allow it to plunge directly into workpiece material. Manufactured from micrograin solid carbide with a bright uncoated finish, this end mill suits machinists and toolroom operators working on close-tolerance profiling, slotting, and contouring passes where corner radius blending is required.

This end mill is suited for use in CNC machining centers and manual knee mills handling ferrous and non-ferrous stock. The single-end configuration and 40-degree helix angle make it effective for light-to-medium material removal where controlled chip evacuation and surface finish quality are priorities. It is a standard choice for job shops, toolrooms, and production machining cells requiring repeatable corner radius geometry on milled features.

Key Features

• 1/4 inch mill diameter with 0.06 inch corner radius for blended edge profiling
• Micrograin solid carbide construction for rigidity and wear resistance
• 2-flute right-hand spiral geometry with centercutting capability
• 40-degree helix angle for efficient chip evacuation
• Bright uncoated finish suitable for a range of workpiece materials
• Single-end design with 3/4 inch length of cut and 2-1/2 inch overall length

Compatibility

Designed as a standard 1/4 inch shank corner radius end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems accepting 1/4 inch round shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding and runout verification procedures. Ensure the shank is fully seated and clamped to the minimum grip depth recommended for the holder type in use. Verify spindle and holder runout before committing to finish passes, as micrograin carbide tooling is sensitive to excessive runout. Consult applicable shop safety procedures and machine tool manufacturer guidelines before operating.
