Kyocera TPC01936 Insert Screw Torx Drive M4 X 0.7

Product Description

The KYOCERA TPC01936 is an insert screw designed to secure indexable cutting inserts in milling toolholders. Using a Torx drive interface, this screw threads into the insert pocket at M4 x 0.7 and clamps the insert firmly in place during cutting operations. The overall length is 7.70 mm, which aligns with standard insert pocket geometry for this screw class. Machinists and tool crib technicians install these screws when replacing worn or damaged clamping hardware on indexable milling tools. The Torx drive reduces cam-out risk compared to hex styles, maintaining proper torque and insert seating.

This insert screw is used in indexable milling applications where M4 x 0.7 insert screws are specified. It corresponds to industry standard number SB-4070TRN, making it a direct cross-reference for toolholders and milling cutters built to that standard. Suitable for face mills, shoulder mills, and similar indexable milling bodies that accept this screw class. This hardware is a consumable replacement item kept on hand in machine shops and tool rooms servicing CNC and manual milling equipment.

Key Features

• Compatible with insert hardware requiring M4 x 0.7 clamping screws

Compatibility

Matches industry standard number SB-4070TRN. Designed for indexable milling toolholders and cutters that require an M4 x 0.7 Torx drive insert screw conforming to that standard.

Installation Notes

Insert screw replacement is performed by machinists or toolroom technicians during routine insert indexing or toolholder maintenance. Always ensure the milling spindle is powered down and the machine is in a safe state before servicing toolholders. Use the correct Torx key size for the drive recess to avoid stripping the head. Do not reuse visibly worn or damaged insert screws, as compromised clamping hardware can lead to insert movement during cutting.
