Iscar 7000249 Cap Screw Indexables T20 Torx M5 X 0.8

Product Description

The ISCAR 7000249 is a countersunk-head cap screw designed for indexable tooling applications in turning operations. It features an M5 x 0.8 thread, a T20 Torx drive, and an overall length of 0.63 inches (16 mm). The screw is part of the Cut Grip series and is compatible with GHIU-style toolholders, securing either the clamp or the insert. Installation requires a T-20/5 key driver. This hardware is a precision-fit fastener intended for use by machinists and toolroom technicians maintaining or assembling indexable turning tool assemblies.

This cap screw is used in CNC and manual turning setups where GHIU toolholders are employed. It is suited for production and job-shop environments requiring reliable insert retention during metal cutting. Compatible inserts include GIPI 3.00-1.5UL, GIPI 3.00-1.5UR, GIPI 4.00-2.0UL, and GIPI 4.00-2.0UR. The countersunk head profile keeps the fastener flush with the toolholder body, reducing interference with the workpiece and chip flow.

Key Features

• M5 x 0.8 thread for standard GHIU toolholder fitment
• T20 Torx drive for positive engagement and reduced cam-out risk
• Countersunk head sits flush with the toolholder surface
• Compatible with both clamp and insert mounting configurations
• Cut Grip series designation for straightforward replacement sourcing
• Requires T-20/5 key driver for installation and removal

Compatibility

Designed for use with ISCAR GHIU-style toolholders in the Cut Grip series. Confirmed compatible inserts: GIPI 3.00-1.5UL, GIPI 3.00-1.5UR, GIPI 4.00-2.0UL, and GIPI 4.00-2.0UR. Compatible hardware applications include clamp and insert mounting.

Installation Notes

Installation and removal should be performed by a qualified machinist or toolroom technician using a T-20/5 Torx key driver. Ensure the machine spindle is stopped and all motion has ceased before servicing the toolholder. Do not overtighten the screw, as exceeding the recommended seating torque specified in the ISCAR toolholder documentation can damage the insert pocket or strip the thread. Inspect the screw threads and toolholder bore for wear or contamination before reinstalling.
