Kyocera TPC01891 Insert Screw Torx Drive M3 X 0.5 Milling

Product Description

The KYOCERA TPC01891 is an insert screw designed to secure indexable cutting inserts in milling toolholders. It uses a Torx drive head and an M3 x 0.5 thread, providing reliable clamping force to keep inserts seated accurately during cutting operations. This hardware is a consumable component in indexable tooling systems, replaced routinely as part of insert changes or whenever a screw shows wear, stripping, or damage. Machining professionals and tool crib technicians working with indexable milling tools are the primary users.

This insert screw is used in indexable milling applications where M3 x 0.5 insert screws are required. It conforms to industry standard number SB-3080TR, making it a recognized replacement specification across compatible indexable toolholding systems. Typical install scenarios include production machining environments, job shops, and maintenance operations where indexable insert hardware is stocked and replaced on a regular basis.

• Torx drive head for positive engagement and reduced cam-out during installation
• M3 x 0.5 thread size for use in compatible indexable milling toolholders
• Conforms to industry standard SB-3080TR
• Designed specifically for indexable insert clamping applications
• Minimum order quantity of 10 units supports efficient stocking of consumable hardware

Compatibility

Designed as an OEM-style replacement insert screw conforming to industry standard SB-3080TR, compatible with indexable milling toolholders requiring an M3 x 0.5 Torx drive insert screw.

Installation Notes

Insert screws should be installed and removed by machinists or tooling technicians using the correct Torx key to prevent drive recess damage. Always power down and lock out the machine spindle before changing inserts or insert screws. Do not overtighten, as this can strip the thread in the toolholder pocket. Inspect the screw threads and drive recess at each insert change and replace any screw showing wear or deformation.
