Parlec S10-10TA4 Tapping Chuck Straight Shank

Product Description

The PARLEC S10-10TA4 is a tension-compression tapping chuck designed for precision tapping operations on CNC machining centers and rigid tapping setups. It features a 1-inch straight shank and accepts taps up to 9/16 inch in capacity, making it suitable for a wide range of thread-forming and thread-cutting applications. With a projection of 4.43 inches and a nose diameter of 1.39 inches, this chuck provides the reach and clearance needed in production environments. Machinists and tooling technicians use this chuck where controlled axial float is required to protect tap life and thread quality.

The S10-10TA4 is intended for use in production machining environments, including job shops and manufacturing facilities running ferrous and non-ferrous materials. The tension-compression design compensates for minor feed-rate discrepancies between the machine spindle and the tap, reducing tap breakage and extending tool life. It is a non-quick-change unit with a straight modular side connection, suited for installations where a fixed, repeatable tooling setup is preferred over modular quick-change systems.

Key Features

• Tension-compression tapping style compensates for axial feed variation to protect tap integrity
• 1-inch straight shank for secure, concentric mounting in compatible toolholders
• Maximum tap capacity of 9/16 inch covers a broad range of standard tap sizes
• Minimum pipe tap capacity of 1/8 inch supports threaded pipe fitting applications
• Compression range of 0.00 to 0.25 inch and tension of 0.56 inch for controlled float
• Nose diameter of 1.39 inches provides clearance in tight-tolerance workpiece configurations

Compatibility

Designed as an OEM-style tapping chuck for use with tooling systems accepting a 1-inch straight shank connection on CNC machining centers and drill-tap machines requiring tension-compression float.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the spindle fully de-energized and locked out before chuck mounting or tap collet changes. Ensure the shank bore and chuck shank are clean and free of chips or burrs before seating to maintain concentricity. Do not exceed the rated maximum tap capacity, as overloading the chuck body can damage internal tension-compression components. Consult machine tool documentation for draw bar torque and retention force requirements applicable to straight-shank toolholders in your specific spindle interface.
