Micro 100 RAD-6 Concave Radius Tool Bit 3/16 in Carbide

Product Description

The MICRO 100 RAD-6 is a concave radius-cutting tool bit designed for precise radius form turning on metal lathes and manual machining centers. Built with a brazed solid carbide tip, this tool bit delivers the hardness and wear resistance needed to hold accurate radii over extended production runs. The 3/16-inch cutting radius and 3/8-inch square shank make it a compact, rigid choice for finishing concave profiles on ferrous and non-ferrous workpieces. It is right-hand cutting, meaning it feeds from right to left across the workpiece. Machinists and tool-and-die professionals install and operate this type of tooling in standard lathe tool posts and turret holders.

The RAD-6 is suited for use in manual and CNC engine lathe applications where a consistent concave radius is required on a turned part. Typical applications include groove profiles, decorative chamfers, and radius blending operations on small-to-medium diameter workpieces. The 3/8-inch shank fits standard tool holders commonly found in benchtop and mid-size production lathes. This tool bit is appropriate for job shop, maintenance machining, and prototype work where a reliable form tool with a fixed radius is preferred over a custom-ground insert.

Key Features

• Brazed solid carbide tip provides superior hardness and edge retention compared to high-speed steel alternatives
• 3/16-inch concave radius for accurate, repeatable radius form cuts
• 3/8-inch square shank for rigid mounting in standard lathe tool posts and turret holders
• Right-hand cutting direction for conventional left-to-right feed lathe setups
• Compact form factor suitable for small-to-medium lathe work

Compatibility

Designed as an OEM-style form tool bit for use in standard lathe tool posts and turret holders accepting a 3/8-inch square shank.

Installation Notes

Installation and operation of this tool bit should be performed by a qualified machinist familiar with lathe tooling setup. Power down and lock out the lathe spindle before seating or adjusting the tool bit in the holder. Ensure the tool tip is set at the correct center height relative to the workpiece axis before engaging the cut. Do not exceed the recommended feed and speed parameters for the workpiece material and carbide grade in use.
