Accupro 605-MG Threading Tool Bit 5/16 in Solid Carbide

Product Description

The ACCUPRO 605-MG is a single point threading tool bit ground from micrograin solid carbide and configured in the Style E neutral cutting geometry. It carries a 60-degree included angle, making it the right choice for cutting standard 60-degree thread forms on lathes and CNC turning centers. The shank measures 5/16 inches wide by 5/16 inches high, and the overall length is 2.25 inches with a 0.375-inch tip length. Neutral orientation means it can approach the workpiece from either direction, giving machinists flexibility in programming and setup. The micrograin carbide grade holds a sharper edge longer than standard carbide in interrupted cuts and finish threading passes.

This tool bit is used in lathe and turning center applications where single point threading, chamfering, undercutting, or V-grooving is required. It fits standard 5/16-inch square tool holders and boring bar-style holders common in manual and CNC lathes. Typical users include machinists and tool-and-die professionals working in job shops, maintenance shops, and production turning operations. The compact 2.25-inch overall length suits tight-clearance applications and smaller lathe tool posts.

Key Features

• Micrograin solid carbide construction for extended edge life and sharper geometry retention
• 60-degree included angle supports standard unified and metric thread forms
• Neutral cutting direction allows left-to-right or right-to-left threading approaches
• Style E geometry rated for threading, chamfering, undercutting, and V-grooving operations
• 5/16 inch square shank fits widely available tool holders without adapters
• Compact 2.25-inch OAL reduces overhang and chatter in confined tool post setups

Compatibility

Designed as a direct-fit replacement for Style E single point threading tool bits in standard 5/16-inch square shank tool holders used on manual and CNC lathes. Industry Standard Number E-5 identifies this geometry across multiple tooling catalogs.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the lathe spindle before seating or removing tool bits from the holder. Secure the shank firmly in the tool holder to the full depth of the pocket to minimize deflection during threading passes. Inspect the carbide tip for edge chips or cracks before use, as micrograin carbide is brittle under side impact.
