Accupro 12182347 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 12182347 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. With a 1 inch cutting diameter, a 1.75 inch length of cut, and a 0.01 inch corner radius, this tool delivers controlled edge geometry that reduces stress concentration at part corners and extends tool life in demanding cuts. The 4-flute, right-hand spiral configuration provides efficient chip evacuation and a stable cutting action suited to ferrous and non-ferrous materials. Machined from micrograin carbide stock and left in a bright uncoated finish, this end mill is installed by CNC machinists and manual mill operators working in job shops, tool rooms, and production environments.

This end mill is built for profiling, slotting, and contouring operations where a small corner radius is required to meet part print tolerances. The centercutting design allows plunge entry, giving operators flexibility in tool paths without requiring a pre-drilled start hole. With a 1 inch shank diameter and 4 inch overall length, it seats directly in standard ER or end mill holders sized for 1 inch straight shanks. The single-end configuration and right-hand cutting direction are consistent with conventional CNC vertical and horizontal milling setups.

Key Features

• 0.01 inch corner radius reduces stress risers and meets tight fillet requirements on finished parts
• Micrograin solid carbide construction provides rigidity and wear resistance in hard or abrasive materials
• 4-flute right-hand spiral design balances chip load and surface finish in profiling cuts
• Centercutting geometry enables direct plunge entry without a pilot hole
• Bright uncoated finish suitable for use with or without cutting fluid across a range of materials
• 1 inch shank diameter matches standard collet and end mill holder tooling

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with tool holders accepting a 1 inch straight shank end mill.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Secure the shank fully into a clean, properly sized end mill holder or collet chuck and torque the retention hardware to the holder manufacturer specification. Inspect the shank and holder bore for chips or contamination before seating. Verify spindle direction is set to right-hand rotation before initiating a cut.
