Jacobs 9757 Tap Collet 0.177 Inches Rubber

Product Description

The JACOBS 9757 is a rubber tap collet designed to hold taps securely during threading operations in machine tool and CNC applications. With a collet size of 0.177 inches (4.50 mm) and a minimum collet capacity of 0.094 inches (2.39 mm), this collet provides consistent grip and accurate tap alignment. The rubber construction allows for controlled tension during the tapping cycle, reducing the risk of tap breakage. It is installed by machinists and toolroom technicians working with tapping heads, drill presses, and CNC machining centers that require precise tap holding.

This collet is suited for use in production machining environments where repeatable thread quality is required. It fits tapping head systems that accept rubber-style collets and is appropriate for light-duty to medium-duty tapping operations in ferrous and non-ferrous materials. Through-coolant is not supported by this collet, and it is not designed for tension-compression tapping applications.

Key Features

Compatibility

Designed as a replacement or spare rubber tap collet for tapping heads that accept 0.177-inch collet sizes. Verify collet series compatibility with your specific tapping head model before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the tapping head spindle is fully powered down and locked out before removing or installing any collet. Inspect the collet bore and tapping head seat for debris or wear before seating the collet. Do not force the collet into the holder; proper seating should require only hand pressure or light tool assistance per the tapping head manufacturer guidelines.
