Sumitomo 2G00174 Insert Screw T10 Torx M3 Thread

Product Description

The SUMITOMO 2G00174 is a T10 Torx insert screw designed to secure indexable inserts in indexable insert drill toolholders. With an M3 thread size and a flat head profile, this screw provides the clamping force needed to hold carbide inserts firmly in position during drilling operations. The overall length is 9 millimeters. It belongs to the WDS series and is a standard hardware component used in CNC and manual machining environments. Machinists, tooling specialists, and shop technicians install and replace these screws as part of routine insert changes and toolholder maintenance.

This insert screw is intended for use with indexable insert drill toolholders that require M3 Torx-drive clamping hardware. The T10 Torx drive reduces the risk of cam-out during tightening compared to hex socket designs, which is especially relevant when working in tight toolholder pockets. Typical applications include high-production drilling on machining centers and CNC lathes. The screw is sold individually, with a minimum order quantity of 10 units per purchase transaction.

Key Features

• T10 Torx drive reduces cam-out risk during insert clamping
• M3 thread size compatible with WDS series indexable insert drill holders
• Flat head type sits flush within the toolholder insert pocket
• 9 millimeter overall length fits standard WDS series toolholder screw pockets
• Lightweight at 0.001 pounds for minimal contribution to toolholder assembly weight

Compatibility

Designed for use with indexable insert hardware requiring an M3 thread, T10 Torx-drive insert screw in the SUMITOMO WDS series indexable insert drill platform.

Installation Notes

Insert screw replacement is performed by tooling technicians or machinists during scheduled insert changes or after screw damage. Power down and lock out the machine spindle before accessing the toolholder. Use a calibrated T10 Torx driver or bit to avoid overtorquing, which can strip the screw or crack the insert. Follow the toolholder manufacturer torque guidelines published in the toolholder documentation for M3 clamping screws.
