Description

The SECO 02409609 is a countersunk lock screw designed to secure indexable inserts in cutting tool bodies used across drilling, milling, and turning applications. Featuring an M3 thread size and a TP9 Torx Plus drive, this screw delivers precise torque transfer and reliable insert clamping during high-speed machining operations. With an overall length of 7.20 mm, it fits the compact geometry of indexable toolholders without interfering with chip flow or insert seating. Machinists, tool crib technicians, and CNC setup personnel install and replace these screws as part of routine insert changeovers on production tooling.

This lock screw is suited for use with indexable toolholders in both shop-floor production and job-shop environments. It is compatible with the C03007-T09P insert style and is appropriate for use in drilling, milling, and turning toolholder bodies that accept an M3 countersunk lock screw with a TP9 Torx Plus drive. The minimum order quantity is 10 units; each package contains 1 screw. It is a direct consumable replacement used whenever inserts are swapped or a screw is lost, stripped, or damaged during service.

Compatibility

Compatible with indexable toolholders using the C03007-T09P insert style that require an M3 countersunk lock screw with a TP9 Torx Plus drive, across drilling, milling, and turning tool bodies.

Installation Notes

Lock screw replacement and insert changeovers are performed by machinists or tool crib personnel using a calibrated Torx Plus TP9 key or torque screwdriver. Always power down and lock out the machine spindle before accessing the toolholder. Use only the manufacturer-specified Torx Plus driver to avoid rounding the drive recess. Discard any screw showing thread damage, deformation, or a compromised drive socket, as a failed lock screw can result in insert ejection during cutting.
