Seco 02457030 Lock Screw TP8 Torx Plus M3 Drilling

Product Description

The SECO 02457030 is a lock screw designed to secure indexable inserts in drilling toolholders. It features an M3 thread, a TP8 Torx Plus drive, and a countersunk head profile. At 7.20 millimeters in overall length, this screw provides reliable clamping force to hold the insert firmly in position during cutting operations. It is a standard consumable component used by machinists and tool crib technicians in precision drilling applications where indexable tooling systems are deployed.

This lock screw is intended for use in indexable drilling toolholders that accept M3 threaded clamping screws with a Torx Plus drive interface. It is commonly used in production machining environments, job shops, and maintenance operations where indexable insert tooling requires periodic insert changes. The countersunk head geometry seats flush within the toolholder pocket, keeping the cutting envelope clear during operation. This part is sold individually but carries a minimum order quantity of 10 units.

Key Features

• M3 thread size for compatibility with standard indexable drilling toolholders
• TP8 Torx Plus drive for precise torque application and reduced cam-out risk
• Countersunk head design seats flush within the toolholder insert pocket
• 7.20 millimeter overall length suits standard insert clamping depth requirements
• Designed for indexable insert retention in drilling tool applications

Compatibility

Designed for use with indexable drilling toolholders that require an M3 threaded lock screw with a TP8 Torx Plus drive and countersunk head. Refer to your toolholder documentation to confirm screw specification before ordering.

Installation Notes

Lock screw replacement and insert changes should be performed by a qualified machinist or toolroom technician. Always remove the toolholder from the machine spindle and ensure the machine is powered down and locked out before servicing indexable inserts or clamping hardware. Use a calibrated Torx Plus driver or torque wrench with the correct TP8 bit and follow the toolholder manufacturer's recommended torque specification. Inspect the screw threads and pocket seating surface for wear or damage before reinstalling.
