Jacobs 9750 Tap Collet 0.383 Inches Rubber

Product Description

The JACOBS 9750 is a rubber tap collet designed to hold taps securely during threading operations in machine tool applications. With a collet size of 0.383 inches (9.73 mm) and a minimum collet capacity of 0.176 inches (4.47 mm), this collet provides a reliable grip for taps used in tapping chucks and holders. The rubber construction allows for slight angular compensation, reducing tap breakage on misaligned workpieces. It is sized and configured for use without through-coolant delivery and is not intended for tension-tap configurations. Machinists and tool-room technicians install this collet as part of a standard tapping chuck assembly.

This collet is suited for light-to-medium tapping work on drill presses, CNC machining centers, and manual tapping fixtures where a rigid or floating tap holder accepts rubber-style collets. It is a single-piece component sold individually, making it straightforward to replace worn or damaged collets without purchasing a full chuck assembly. The 0.383-inch collet size addresses a specific tap shank diameter common in general metalworking and production environments.

Key Features

• Collet size of 0.383 inches (9.73 mm) for precise tap shank fitment
• Minimum collet capacity of 0.176 inches (4.47 mm)
• Non-through-coolant design suits standard dry or externally lubricated tapping setups
• Sold as a single unit for targeted replacement without full chuck replacement

Compatibility

Designed as an OEM-style replacement rubber tap collet for tapping chucks and holders that accept 0.383-inch collets of the rubber collet type.

Installation Notes

Installation is performed by machinists or tool-room technicians. Before changing a collet, ensure the machine spindle is fully stopped and the power is locked out per shop lockout/tagout procedures. Insert the collet into the appropriate tapping chuck bore and confirm it seats fully before tightening the chuck retaining nut. Inspect the collet for wear or cracking before each use, as damaged rubber collets can result in tap slippage or breakage.
