Parlec S10-20TA5 Tapping Chuck Straight Shank

Product Description

The PARLEC S10-20TA5 is a tension-compression tapping chuck designed for rigid and floating tap operations on CNC machining centers and tapping machines. It features a 1-inch straight shank and handles taps from 5/16 inch up to 7/8 inch capacity, with a maximum pipe tap capacity of 1/2 inch. The projection measures 5.46 inches, and the nose diameter is 2.18 inches. Built for production environments, this chuck provides up to 0.56 inches of tension travel and 0.00 to 0.25 inches of compression, helping protect tap life and thread quality during through and blind hole tapping operations. Machinists and toolroom technicians are the primary installers.

The S10-20TA5 is suited for use on vertical and horizontal machining centers where a straight-shank modular connection is required. It is applicable in job shops and production facilities running general-purpose tapping operations in materials ranging from aluminum to mild steel. The tension-compression float compensates for minor feed-rate mismatches between the spindle and the tap, reducing tap breakage in high-cycle applications. Pipe tapping from 1/4 inch to 1/2 inch NPT is also within the specified capacity range of this chuck.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the chuck. Verify that the collet or tap adapter selected matches the tap shank diameter and falls within the 5/16-inch to 7/8-inch capacity range of this unit. Follow the machine tool manufacturer's torque and retention specifications for the straight-shank connection - no specific torque values are supplied with this chuck.
