Used in CNC turning centers and manual lathes requiring precise collet-based workholding, the ATS Workholding SC300A-ST5 is a 3J Scroll Collet Chuck Assembly manufactured by Advanced Tool Systems. The Scroll True Length design holds the collet in a fixed axial position during actuation, ensuring consistent linear accuracy across repeated chucking cycles. A 3/8 in. ratchet drives the scroll and pinion mechanism for effortless collet engagement. This assembly accepts standard 3J collets with a 7-degree closing taper angle and a maximum collet capacity of 1-3/4 in., as published by ATS for their 3J scroll chuck line. The chuck body is machined steel with a black oxide finish and features a large rear mounting flange with multiple bolt hole patterns for spindle attachment. Part number SC300A-ST5 is stamped on the body. The date code 06-28-07 is visible on the nameplate. ATS Workholding is a US manufacturer with a broad product line of collet chucks used on a wide variety of CNC lathe brands. The exact spindle mount configuration associated with the ST5 suffix is not confirmed from visible markings alone and should be verified against the machine spindle prior to installation.
