Sumitomo 2G00159 Insert Screw IP20 Torx M5 Thread

Product Description

The SUMITOMO 2G00159 is an insert screw designed to secure indexable cutting inserts in WaveMill milling toolholders. This flat-head Torx screw uses an IP20 drive and M5 thread to clamp inserts firmly against the pocket seat during milling operations. At 11.50 millimeters overall length, it is sized for the clamping geometries found across the WaveMill series. The screw weighs approximately 0.05 pounds. Licensed machinists, tool-crib technicians, and CNC setup personnel handle this hardware as a routine consumable during insert indexing and toolholder maintenance.

This screw is used in milling applications where WaveMill indexable toolholders require insert retention hardware. It is compatible with inserts having an inscribed circle of 0.375 inches, 0.500 inches, 0.750 inches, or 1.000 inch. Typical install scenarios include production shops running face milling, shoulder milling, or high-feed milling operations where periodic insert changes demand reliable, repeatable clamping hardware. Replacement of worn or damaged insert screws is a standard part of toolholder preventive maintenance.

Installation Notes

Insert screw installation and replacement is performed by machinists or tool-crib technicians during scheduled toolholder maintenance or at insert index intervals. Always de-energize and lock out the machine spindle before accessing the toolholder. Use a calibrated IP20 Torx driver or insert-screw torque wrench set to the toolholder manufacturer torque specification for M5 insert screws. Inspect the screw threads and pocket seat for contamination or damage before installation; debris under the screw head can cause insert seating errors and premature failure.
