Kyocera TPC01846 Insert Screw Torx Drive M2 X 0.4

Product Description

The KYOCERA TPC01846 is a Torx drive insert screw designed to secure indexable cutting inserts in milling toolholders. It features an M2 x 0.4 thread and an overall length of approximately 0.19 inches (4.80 mm), providing a compact, precise clamping solution in tight toolholder pockets. Conforming to industry standard SB-2050TR, this screw is a direct specification match for toolholders that call out that standard. Installation and replacement are handled by CNC machinists and toolroom technicians during insert indexing or changeover.

This insert screw is intended for indexable milling applications where a Torx drive fastener is required to clamp carbide or cermet inserts into a toolholder seat. The small M2 thread diameter is common in high-density milling cutters and smaller-diameter toolholders. It is sold individually, making it a practical replacement option when a single screw is lost or damaged during routine insert changes on the shop floor or in a toolroom environment.

Key Features

• Torx drive design reduces cam-out risk during insert clamping and removal
• M2 x 0.4 thread size conforms to industry standard SB-2050TR
• Overall length of 4.80 mm (approximately 0.19 inches) suits compact milling toolholder pockets
• Designed specifically for indexable insert hardware compatibility
• Sold as a single unit for direct one-for-one replacement

Compatibility

Compatible with indexable milling toolholders requiring an M2 x 0.4 Torx drive insert screw conforming to industry standard SB-2050TR. Verify toolholder documentation before ordering to confirm thread size and drive type.

Installation Notes

Insert screw replacement is performed by machinists or toolroom technicians. Always power down and lock out the machine spindle before accessing the toolholder. Use the correct Torx key or driver bit sized for M2 insert screws to avoid stripping the drive recess. Do not overtighten; follow the toolholder manufacturer torque specification documented in the toolholder's technical data sheet.
