Accupro 718-MG Single Point Tool Bit Micrograin Carbide Rh

Product Description

The ACCUPRO 718-MG is a right-hand, offset threading single point tool bit designed for precision threading and V-grooving operations on CNC and manual lathes. Built to ER-12 industry standard, it features a micrograin solid carbide tip brazed to a steel shank. The 60-degree included angle suits standard unified and metric thread forms. At 4.5 inches overall length with a 3/4-inch square shank, the 718-MG offers rigid setup and consistent tool-post clamping in a compact profile suited to production turning environments. The offset geometry allows threading closer to a shoulder than straight-style tooling.

This tool bit is used in threading and V-grooving-to-shoulder applications where clearance near a workpiece shoulder is required. The right-hand cutting direction means material is fed from right to left in standard lathe orientation. It is a common choice for machinists, toolroom operators, and production floor setups running external thread profiles on steel, stainless, and non-ferrous materials. The ER tool style designation and ER-12 industry standard number make it a recognized replacement or addition in shops already running ER-series tooling systems.

Key Features

• Micrograin solid carbide tip for wear resistance on ferrous and non-ferrous materials
• 60-degree included angle supports standard unified and metric external thread forms
• Offset threading geometry allows threading up to a shoulder with minimal clearance
• Right-hand cutting direction for conventional lathe feed
• ER-12 industry standard designation for recognized cross-reference fitment
• 3/4-inch square shank seats securely in standard tool posts and holders

Compatibility

Conforms to ER-12 industry standard. Designed for use in tool posts and holders that accept a 3/4-inch square shank single point tool bit in ER-style offset threading configurations.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully in the tool post holder before operation and ensure the cutting edge is set to correct center height for the workpiece. Power down and lock out the lathe spindle before changing or adjusting tooling. Inspect the carbide tip for chipping or wear before each use, as a damaged tip will produce out-of-tolerance thread forms.
