Kyocera TPC01870 Insert Screw Torx M2.5x0.45

Product Description

The KYOCERA TPC01870 is a Torx-drive insert screw designed to clamp indexable cutting inserts onto milling toolholders. These small-format screws use an M2.5 x 0.45 thread pitch and require a Torx driver for installation and removal. Proper insert clamping torque is critical in indexable tooling - an under-torqued or over-torqued screw can cause insert movement, chatter, or premature insert failure. The TPC01870 is a consumable fastener that should be inspected and replaced regularly as part of routine toolholder maintenance. Machinist and toolroom professionals working with indexable milling systems are the primary users.

This insert screw is used in indexable milling toolholders where the insert seat requires an M2.5 x 0.45 Torx clamping screw. Indexable milling applications include face milling, shoulder milling, and helical interpolation operations across a range of workpiece materials. The screw is compatible with toolholders that accept hardware matching the industry standard number SB-2560TR. It is sold individually but must be ordered in a minimum quantity of 10 units.

Key Features

• M2.5 x 0.45 thread size fits standard indexable milling insert seats
• Torx drive reduces cam-out risk during insert changes compared to hex drives
• Industry standard number SB-2560TR for cross-reference identification
• Lightweight at 0.02 pounds per unit - suitable for high-quantity stocking
• Minimum order quantity of 10 units supports toolroom consumable stocking practice

Compatibility

Compatible with indexable milling toolholders requiring an M2.5 x 0.45 Torx insert screw with industry standard reference SB-2560TR. Verify toolholder OEM specifications before substituting any insert clamping hardware.

Installation Notes

Insert screws should be installed by a qualified machinist or toolroom technician familiar with indexable tooling. Always use a calibrated Torx torque driver and follow the toolholder manufacturer's specified clamping torque - do not estimate by feel. Inspect the screw threads and the toolholder seat threads for wear or damage before each insert change. Replace the screw at any sign of thread deformation, head rounding, or corrosion to prevent insert instability during cutting.
