Internal Tool 80-6030 Convex Radius Cutter Solid Carbide

Product Description

The INTERNAL TOOL 80-6030 is a solid carbide convex radius cutter designed for profiling and contouring operations on metallic workpieces. With a cutter radius of 0.0625 inches and a cutter diameter of 0.3125 inches, this six-flute tool delivers precise convex profiles in a single pass. The profile-ground relief style ensures accurate geometry and consistent edge sharpness across the full cutting arc. The uncoated carbide construction suits applications where coating buildup tolerance is critical or where regrinding is anticipated. Machinists and tool-and-die professionals select this cutter for detail work requiring tight radius control and repeatable results.

This cutter is intended for use on CNC machining centers and manual mills handling steel, stainless steel, cast iron, non-ferrous metals, super alloys, and titanium. The 0.3125-inch shank connects directly to standard collet or end-mill holders. The 0.1500-inch neck diameter and 0.3125-inch neck length allow access to moderate-depth features without interference. The 0.1250-inch cutting width makes it well suited for narrow groove profiles, bearing seats, and radius blending operations on precision components.

Key Features

• Solid carbide construction for rigidity and wear resistance across hard workpiece materials
• Profile-ground relief style maintains accurate convex radius geometry at the cutting edge
• Six-flute design increases feed rates and improves surface finish compared to lower flute-count alternatives
• 0.0625-inch cutter radius for tight, precise convex profiles
• Uncoated finish compatible with regrinding services and low-coating-tolerance applications
• Compatible workpiece materials span ISO material codes P, M, K, N, and S

Compatibility

Designed for use on steel, stainless steel, cast iron, non-ferrous metals, super alloys, and titanium workpieces. Fits standard 0.3125-inch collet and end-mill holder systems. Part of the INTERNAL TOOL Series 80 convex radius cutter lineup.

Installation Notes

Installation is performed by machinists or toolroom personnel using a standard collet chuck or side-lock end-mill holder sized for a 0.3125-inch shank. Confirm the holder is clean and free of debris before seating the cutter to ensure runout is minimized. Power down and lock out the spindle before changing tooling in accordance with machine-specific safety procedures. Verify cutting parameters against the workpiece material and machine rigidity before full-depth engagement.
