Parlec ERT20-10 ER20 Tap Collet Size 10 Tension

Product Description

The PARLEC ERT20-#10 is an ER20 series tap collet designed to hold size 10 hand taps in tension-style tapping applications. It fits standard ER20 collet chucks and provides secure, concentric clamping during tapping cycles on CNC machining centers and manual machines alike. The collet supports tension tapping, which allows the tap to float axially to compensate for slight feed-rate mismatches between the spindle and the tap pitch. At 0.13 pounds, it is a lightweight tooling component suited for high-frequency use in production and job-shop environments. Installation and changeover are fast within any ER20-compatible chuck body.

This collet is used wherever ER20 tap holders are employed for hand-tap sizes in the number 10 designation. Typical applications include tapping ferrous and non-ferrous materials on vertical or horizontal machining centers, drill presses, and tapping machines. It is a standard choice in general metalworking, mold and die, and precision machining shops. The tension-style design makes it well suited for rigid-tapping setups where minor axial compensation improves tap life and thread quality. Through-coolant is not supported by this collet.

Compatibility

Designed for use with ER20-compatible tap chuck bodies that accept tension-style tap collets. Fits hand tap size 10. No specific compatible chuck model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with ER-style collet systems. Ensure the machine spindle is fully stopped and locked out before changing collets. Seat the collet fully into the ER20 nut before threading onto the chuck body, and torque the nut with the appropriate ER20 collet wrench to the chuck manufacturer's specified value. Inspect the collet bore and chuck taper for chips or damage before each use to ensure accurate tap alignment.
