Kennametal 1105612 Cap Screw Indexables T9 Torx

Product Description

The KENNAMETAL 1105612 is a T9 Torx drive cap screw designed to secure indexable inserts in drilling toolholders. This small-format fastener is a critical component in indexable cutting tool assemblies, holding the insert firmly in the pocket during high-feed drilling operations. Weighing 0.05 pounds, it is a lightweight but precision-critical part. Replacement and stocking of these screws is standard practice for machinists and toolroom technicians who maintain indexable tooling, as insert screws are subject to wear, stripping, and loss during routine insert changes.

This cap screw is used in metalcutting environments where indexable drilling tools are employed — typically CNC machining centers, turning centers with live tooling, and manual drill press setups using indexable drill bodies. The T9 Torx drive provides positive engagement during tightening, reducing cam-out risk compared to hex drives. It is sold individually per package with a minimum order quantity of 10 units, making it suitable for stocking in toolroom cribs or including in toolholder maintenance kits.

Key Features

• T9 Torx drive for positive, cam-out-resistant insert clamping
• Designed specifically for indexable drilling toolholders
• Secures indexable inserts in the insert pocket during cutting operations
• Lightweight construction at 0.05 pounds per screw
• Minimum order quantity of 10 units supports toolroom stocking and crib inventory

Compatibility

Designed as an OEM-style replacement cap screw compatible with KENNAMETAL indexable drilling tools that require a T9 Torx drive insert clamping screw. Confirm screw size and drive type against the specific toolholder documentation before ordering.

Installation Notes

Insert screw replacement and tightening should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before changing inserts or replacing clamping screws. Use the correct T9 Torx key or bit to tighten the screw — do not substitute a drive tool that does not fully engage the recess, as this risks stripping the head. Follow the toolholder manufacturer torque guidance for the specific toolholder model when available.
