Accupro 12177325 Corner Radius End Mill 0.8 Mm 2 Flute Carbide

Product Description

The ACCUPRO 12177325 is a solid carbide corner radius end mill designed for precision milling in tight-tolerance machining applications. With a 0.8 mm cutting diameter and a 0.1 mm corner radius, it is engineered for small-feature work where edge integrity and dimensional accuracy are critical. The micrograin carbide construction supports rigidity and wear resistance at this diameter. It is a single-end, centercutting tool with a right-hand flute direction and right-hand cutting orientation. Machinists and tool-and-die professionals use this style of end mill for profiling, slotting, and contouring in ferrous and non-ferrous materials.

This end mill is suited for high-precision CNC milling operations in job shops, mold making, and production environments where small-diameter tooling is required. The extended reach design, with a 16 mm reach length and 4 mm shank diameter, allows access to deeper features without sacrificing tool stability. The 30-degree helix angle promotes smooth chip evacuation in confined cutting zones. It is typically used in vertical machining centers with high-speed spindle capability appropriate for sub-millimeter tooling.

Key Features

• 0.8 mm cutting diameter with tight mill diameter tolerance (+0.0002 to -0.0008 inches) for precision fitment
• 0.1 mm corner radius reduces stress concentration and improves surface finish on profiled edges
• Micrograin solid carbide construction for rigidity and extended tool life at small diameters
• Extended reach design with 16 mm reach length for accessing deeper part features
• 30-degree helix angle promotes chip flow in confined cuts
• Bright/uncoated finish suitable for a wide range of base materials without coating compatibility concerns

Compatibility

Designed for use in CNC machining centers accepting a 4 mm shank diameter. Suited for small-feature milling in mold making, die work, and precision component manufacturing.

Installation Notes

Installation should be performed by a qualified machinist following established toolroom practices. Ensure the spindle and tool holder are clean and free of debris before seating the 4 mm shank. Verify runout with a dial indicator before cutting, as runout is especially critical at sub-millimeter diameters. Do not exceed the tool manufacturer's recommended speeds and feeds for the material and coating type in use.
