Specification Quick Change Tap Collets
The Onpin TC Series (including detailed sub-models such as TCJIS, TCISO, TCDIN371, TCDIN376, and TCANSI) is a premium range of torque control tap collets designed for precision threading operations. Operating with an integrated torque-limiting clutch, it automatically slips when encountering excessive resistance, effectively preventing tap breakage during internal thread tapping. Featuring a compact design with a standard 19 mm mounting shank and a 0.3 kg weight, it covers a broad clamping range from M3 to M12.
Key Features of Onpin TC Series
- Tap Overload Protection: Built-in torque limit control mechanism slips automatically upon overload to safeguard expensive taps.
- Comprehensive Global Standards: Available in dedicated configurations conforming to JIS (Japan), ISO (International), DIN 371 / DIN 376 (Germany), and ANSI (USA) standards.
- Wide Tapping Capacity: Accommodates tap sizes from M3 to M12 (including fractional inch sizes such as 1/8", 3/16", 1/4", 5/16", 3/8", 7/16", 1/2").
- Compact & Lightweight: Weighs only 0.3 kg with a 32 mm outer diameter and a 19 mm mounting shank for easy integration.
- Precise Dimension Matching: Custom-fitted according to the exact shank diameter ($\varnothing d$) and square drive size ($\square$) of specified taps.
