Sumitomo 2G00473 Insert Screw T10 Torx M3 Indexable

Product Description

The SUMITOMO 2G00473 is a flat-head insert screw designed to secure indexable cutting inserts on turning toolholders. It uses a T10 Torx drive and M3 thread, providing reliable clamping force during machining operations. At 6.50 mm overall length, the screw fits the insert pocket without interfering with chip flow or the cutting edge. This hardware is a consumable component routinely replaced by machinists, toolroom technicians, and CNC setup personnel as part of routine indexable tooling maintenance.

This insert screw is intended for use with indexable turning toolholders in the Sumitomo Dual Clamp, SumiTurn T-Rex, Sumiboron, and Swiss series tooling lines. It is suited for both production turning and precision turning applications where positive insert clamping is required. The M3 thread size and T10 Torx drive configuration are common across a range of standard indexable insert pocket designs used on CNC lathes and Swiss-type turning centers.

Key Features

• T10 Torx drive for positive, slip-resistant engagement during tightening
• M3 thread size for compatibility with standard indexable turning toolholder pockets
• Flat head design seats flush within the insert clamp pocket
• 6.50 mm overall length fits within the clamping zone without overhang
• Compatible with Dual Clamp, SumiTurn T-Rex, Sumiboron, and Swiss series toolholders

Compatibility

Designed for use with indexable inserts in the Sumitomo Dual Clamp, SumiTurn T-Rex, Sumiboron, and Swiss series turning toolholders requiring an M3 thread, T10 Torx drive insert screw.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert indexing or replacement. Always ensure the spindle is locked out and the machine is in a safe state before servicing toolholders. Use a calibrated T10 Torx driver or torque wrench with the appropriate bit; follow the toolholder manufacturer's specified clamp torque for M3 insert screws. Inspect the screw threads and pocket threads for wear or damage before reinstalling to prevent insert movement during cutting.
