Value Collection S 161 Tap Collet 0.1772 in 4.50 Mm

Product Description

The VALUE COLLECTION S 161 is a rubber tap collet designed to hold taps securely during threading operations in machine tool setups. The collet accepts a decimal inch size of 0.1772 inches (4.50 mm) and has a minimum collet capacity of 0.0984 inches (2.5 mm). Rubber construction provides a controlled grip that helps protect tap shanks from damage during installation and removal. This collet is intended for use in tapping chucks and collet-style tap holders on manual or CNC machining equipment. Machinists and toolroom technicians install this type of collet as part of a standard tap holding system.

This tap collet is suited for light-duty tapping applications where a rubber-grip collet interface is required. It is a direct-fit component for compatible tap collet holders accepting a 0.1772-inch (4.50 mm) collet size. Typical install scenarios include production tapping on drill presses, machining centers, and tapping arms where consistent tap alignment and grip retention are required. Through-coolant is not supported on this collet.

Compatibility

Designed as an OEM-style replacement or standard fit collet for tap holders and tapping chucks that accept a 0.1772-inch (4.50 mm) rubber tap collet.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before inserting or removing the collet, ensure the machine spindle is fully stopped and locked out per applicable machine safety procedures. Seat the collet fully into the tap holder before tightening the retaining nut to ensure concentricity and prevent tap runout. Do not overtighten the collet nut, as rubber collets are subject to deformation under excessive clamping force.
