Iscar 3110840 Drill Extension Collet

Product Description

The ISCAR 3110840 is a drill extension collet designed to increase the reach of compatible drilling tools in metalworking and machining applications. This accessory mounts between a drill and the machine spindle or toolholder, allowing deeper hole drilling without changing the base tool setup. It is used by machinists and tool-and-die professionals working on CNC machining centers, lathes, and similar equipment. The unit weighs 0.01 pounds, making it a lightweight addition to a tooling setup. Proper tool engagement and runout control are critical with extension collets of this type.

This drill extension collet is suited for production and job-shop environments where standard drill reach is insufficient for the workpiece geometry. It is appropriate for use in both vertical and horizontal machining centers. The part ships in a package quantity of one and carries an UNSPSC code of 27112800, classifying it within the cutting tools and accessories category.

Key Features

• Extends drilling reach beyond standard tool length without requiring a different base drill
• Lightweight construction at 0.01 pounds for minimal spindle load impact
• Package quantity of one for single-unit procurement flexibility
• UNSPSC code 27112800 for streamlined procurement classification

Compatibility

Designed as an OEM-style drill extension collet for use with compatible ISCAR drilling toolholders and spindle interfaces in CNC machining applications. Confirm spindle interface and collet bore specifications against your machine and drill shank dimensions before installation.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder and collet systems. Power down and lock out the machine spindle before mounting or removing any tooling. Ensure mating surfaces are clean and free of chips or burrs before seating the extension collet. Follow the machine tool manufacturer and ISCAR tooling guidelines for proper torque and clamping procedures.
