Accupro 12177335 Corner Radius End Mill 1.2mm 2 Flute Carbide

Product Description

The ACCUPRO 12177335 is a solid carbide corner radius end mill designed for precision milling in metalworking and machining applications. With a 1.2 mm cutting diameter and a 0.10 mm corner radius, this single-end tool delivers tight-tolerance profiling and slotting in hard and abrasive materials. The micrograin carbide substrate provides the rigidity and wear resistance needed for consistent performance at small diameters. At 57 mm overall length with a 6 mm shank diameter and 15 mm reach length, it fits standard collet chucks used in CNC machining centers and manual mills. Installation and use are performed by machinists and CNC operators working to close tolerances.

This end mill is suited for precision contouring, profiling, and slotting operations in aerospace, mold and die, medical device, and general precision machining environments. The 30-degree helix angle and right-hand spiral flute geometry promote chip evacuation in shallow cuts. The centercutting design allows plunge entry. The bright, uncoated finish makes it appropriate for non-ferrous metals and plastics where coating buildup is a concern, as well as for applications where post-machining inspection of the cutting edge is required.

Key Features

• 1.2 mm cutting diameter with 0.10 mm corner radius for fine detail and blend radii
• Micrograin solid carbide construction for rigidity and edge retention at small diameters
• 2-flute, right-hand spiral geometry with 30-degree helix angle for efficient chip clearance
• Centercutting design allows direct plunge entry without pre-drilling
• Extended reach configuration with 15 mm reach length for accessing deeper features
• Bright, uncoated finish suitable for non-ferrous materials and inspection-sensitive applications

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 6 mm shank diameter collet or end mill holder.

Installation Notes

Installation is performed by machinists using a calibrated collet chuck or end mill holder rated for the 6 mm shank diameter. Confirm runout at the shank before beginning a cut, as small-diameter carbide tools are sensitive to spindle and holder runout. Always verify correct tool projection and reach length against the programmed toolpath before engaging the workpiece. Handle carbide end mills carefully to avoid chipping the cutting edges during setup and storage.
