Accupro 12177351 Corner Radius End Mill 3mm 2-flute Carbide

Product Description

The ACCUPRO 12177351 is a solid carbide corner radius end mill designed for precision milling in metal and composite materials. It has a 3 mm cutting diameter with a 0.25 mm corner radius, a 3 mm length of cut, and a 30-degree helix angle. The micrograin carbide construction provides edge retention and dimensional consistency in tight-tolerance applications. This is a single-end, centercutting tool, meaning it can plunge directly into material as well as cut along the side. Machinists and toolroom operators working on CNC machining centers and manual mills will find this tool suited for fine detail work and profiling where corner geometry control is critical.

This end mill is intended for use in precision machining environments, including die and mold work, medical component manufacturing, and aerospace part production where small-diameter corner radius geometry is required. The bright/uncoated finish makes it suitable for non-ferrous metals, plastics, and general-purpose ferrous materials where coatings are not required. The 6 mm shank diameter with an 8 mm reach length and 57 mm overall length fits standard collet chucks and end mill holders common on vertical machining centers.

Key Features

• 3 mm cutting diameter with 0.25 mm corner radius for controlled edge geometry
• Micrograin solid carbide construction for rigidity and extended tool life
• Centercutting design allows direct plunge entry without pre-drilling
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Right-hand flute direction and right-hand cutting for standard CNC spindle operation
• Extended reach with 8 mm reach length and 57 mm overall length for deeper cavity access

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or holder to the recommended gauge depth before tightening. Verify runout with a dial indicator after tool change to confirm seating and minimize premature wear.
