Sumitomo 2G00151 Insert Screw 8IP Torx M3 Thread

Product Description

The SUMITOMO 2G00151 is a flat-head insert screw designed to secure indexable cutting inserts in compatible milling toolholders. Using an 8IP Torx drive and M3 thread, this screw provides consistent clamping force and positive seating for indexable inserts across milling applications. The flat head profile sits flush within the insert pocket, reducing interference with chip flow during cutting operations. At 5.30 mm overall length and a package weight of 0.03 pounds, the 2G00151 is a precision fastener intended for use by machinists and tooling technicians maintaining CNC milling toolholders in production environments.

This insert screw is compatible with the SUMITOMO SumiMill and WaveMill series toolholders. It is suited for indexable milling insert sizes with inscribed circles of 0.25000, 0.33500, and 0.47200 inches, corresponding to WDMT 0603, WDMT 0804, and WDMT 1205 insert families. Typical use is in horizontal and vertical machining centers where frequent insert indexing requires reliable, repeatable fastener performance. This item is sold individually but carries a minimum order quantity of 10 units.

Compatibility

Designed for use with SUMITOMO SumiMill and WaveMill series indexable milling toolholders. Compatible insert families include WDMT 0603, WDMT 0804, and WDMT 1205 series inserts with inscribed circles of 0.25000, 0.33500, and 0.47200 inches respectively.

Installation Notes

Insert screw replacement is performed by tooling technicians or machinists during scheduled insert indexing or toolholder maintenance. Always ensure the toolholder is removed from the spindle and the machine is in a safe, powered-down state before servicing insert pockets. Use a calibrated 8IP Torx key or bit to seat the screw; do not substitute drive sizes, as improper tooling can damage the screw head or insert pocket threads. Inspect the insert pocket seat and threads for wear or contamination before installing a replacement screw.
