Micro 100 RAD-2 Concave Radius Cutting Tool Bit

Product Description

The MICRO 100 RAD-2 is a concave radius cutting tool bit designed for precision form turning and profiling operations on a lathe. It cuts a 1/16 inch concave radius profile in a single pass, making it well suited for creating fillets, grooves, and decorative radii on ferrous and non-ferrous workpieces. The tool mounts in a standard 3/8 inch square tool holder, which is a common size for bench and toolroom lathes. Machinists and toolmakers reach for this bit when consistent, repeatable radius geometry is required without the setup time of a custom ground tool.

The RAD-2 is used in machine shop and toolroom environments for small-scale lathe work where close-tolerance form features are specified on prints. Typical applications include shaft undercuts, bearing seat radii, and decorative turning on components produced in low to medium volumes. The compact 3/8 inch shank fits most standard quick-change and lantern-style tool posts found on smaller engine lathes and toolroom machines.

Key Features

• Concave cut type produces a precise inward radius profile
• 1/16 inch radius for small-scale form turning and fillet work
• 3/8 inch square shank for compatibility with standard tool holders
• Single-point geometry allows radius to be cut in one pass
• Compact form factor suited to bench lathes and toolroom machines

Compatibility

Designed as an OEM-style form tool for use in 3/8 inch square tool holders on standard engine lathes and toolroom lathes.

Installation Notes

Installation is performed by a machinist or toolmaker during lathe tooling setup. Secure the shank firmly in the tool holder and verify center height before taking a cut. Ensure the lathe is fully stopped and the spindle is locked before mounting or adjusting the tool bit. Follow standard machine shop safety practices and consult the machine manufacturer guidelines for proper tool-post torque and cutting speeds.
