Jacobs 9751 Tap Collet 0.383 Inches Rubber

Product Description

The JACOBS 9751 is a rubber tap collet designed to hold taps securely during threading operations on CNC machines, drill presses, and tapping heads. With a collet size of 0.383 inches (9.73 mm) and a minimum collet capacity of 0.253 inches (6.43 mm), this collet provides a firm, vibration-dampening grip on tap shanks within that range. The rubber construction allows for slight radial float, which helps reduce tap breakage by accommodating minor misalignment between the tap and the threaded hole. Machinists and tool-room technicians install this collet as part of a tapping attachment or quick-change tap holder system.

This tap collet is suited for production and job-shop environments where accurate, repeatable thread cutting is required. It fits into compatible JACOBS tapping chucks and quick-change systems that accept 0.383-inch rubber collets. Typical applications include threading ferrous and non-ferrous materials on manual or CNC equipment. The collet is sold individually and is a direct replacement for worn or damaged collets in existing tapping setups.

Compatibility

Designed as an OEM-style replacement collet for tapping chucks and quick-change tapping systems that accept 0.383-inch rubber tap collets.

Installation Notes

Installation is performed by machining professionals or toolroom technicians familiar with tapping attachments. Before installing or removing collets, ensure the machine spindle is fully stopped and the power is locked out per standard LOTO procedures. Seat the collet fully into the collet nut or holder body and verify it is secure before beginning any tapping cycle. Inspect the collet for wear or deformation regularly, as a damaged rubber collet can cause tap runout and thread quality issues.
