Allied Machine 7514N-IP20-1 Insert Screw TP20 Torx Plus

Product Description

The ALLIED MACHINE AND ENGINEERING 7514N-IP20-1 is a flat head insert screw designed for use with indexable drilling toolholders. It accepts a TP20 Torx Plus drive and features a 1/4 inch thread size, securing carbide inserts firmly in place during cutting operations. This hardware is part of the T-A Series system and is installed by machinists and toolroom technicians working with indexable drill bodies on CNC machining centers and manual drill presses. The correct clamping screw is a critical component for maintaining insert seating and repeatability under high-feed drilling conditions.

This insert screw is intended for use in indexable drilling applications across production and job shop environments. It is compatible with the T-A Series toolholders listed below and is driven using the 8IP-20 key driver. Facilities running high-volume drilling programs depend on stocking replacement hardware such as this screw to minimize downtime during insert changes. The flat head profile ensures a low-profile, flush seating that does not interfere with chip evacuation or workpiece clearance.

Key Features

• TP20 Torx Plus drive for positive engagement and reduced cam-out during tightening
• 1/4 inch thread size compatible with T-A Series indexable drill bodies
• Flat head design seats flush to prevent interference with chip flow
• Compatible with 8IP-20 key driver for consistent torque application
• Designed for indexable insert retention in drilling toolholders
• Industry Standard Number 7514N-IP20-1 for cross-reference ordering

Compatibility

Compatible with the following T-A Series toolholders: 23030H-150F, 23030H-40FM, 24030H-150F, 24030H-40FM, 24040H-150F, and 24040H-40FM. Requires the 8IP-20 key driver for installation.

Installation Notes

Installation is performed by machinists or toolroom personnel during indexable insert changes. Power down and lock out the machine spindle before accessing the toolholder. Use only the specified 8IP-20 Torx Plus key driver to seat and tighten the screw — substituting an incorrect driver can strip the Torx Plus socket or under-torque the fastener. Inspect the screw threads and toolholder bore for damage or debris before reinstalling.
