The ACCUPRO 400-MG is a single point tool bit designed for precision metal cutting operations on lathes and manual turning centers. Built with a micrograin solid carbide tip rated at industry standard C-4, it delivers consistent edge retention and wear resistance across a range of workpiece materials. The shank measures 0.25 inches wide by 0.25 inches tall, and the overall length is 2 inches. The square nose geometry with neutral cutting direction makes this bit suitable for straight turning passes as well as facing and chamfering without requiring left- or right-hand orientation adjustments. Machinists and tool-and-die professionals are the primary users of this style of cutting tool.
This tool bit is suited for manual lathes and CNC turning setups where a compact, 0.25-inch shank tool bit is required. Cutting applications include chamfering, facing, forming, and general-purpose turning. The C-4 carbide grade is appropriate for machining cast iron, steel alloys, and similar ferrous materials at moderate to high surface speeds. The 5/16-inch tip length provides adequate chip clearance for typical depth-of-cut ranges used in finish and semi-finish turning operations. It ships individually and is packaged in single-unit quantity.
Designed for use in lathe and turning machine tool holders accepting a 0.25 inch square shank single point tool bit.
Installation is performed by a machinist or toolroom technician. Power down and lock out the lathe spindle before seating or adjusting the tool bit in the holder. Secure the shank fully within the tool holder and verify center height alignment before taking a cut. Do not exceed the tool holder clamping torque recommendations specified by the tool holder manufacturer.
