The CoroThread® 266 thread-turning tool from Sandvik Coromant is available from 1st March 2018 with precision over- and under-coolant to improve process security and maximise efficiency. The addition of over-coolant improves chip formation for more secure machining, while under-coolant controls temperature for long and predictable tool life. Precision coolant also has positive effects on surface finish, further supporting the generation of high-quality threads.
“Process security and stability is paramount in thread-turning operations to ensure the machining of right-first-time threads, every time,” explains Hampus Olsson, Product Manager Thread Turning at Sandvik Coromant. “Along with precision coolant, this is why CoroThread 266 features the proprietary iLock interface between the holder and insert, which prevents cutting forces from causing micro-movements of the insert in the tip seat. In addition, for applications where long overhangs are unavoidable, the use of dedicated damped Silent Tools adaptors provide a proven way to reduce vibration and maintain precision.”
Ideal for external and internal thread turning, a wide standard assortment of insert thread profiles with dedicated grades and geometries is available for all materials. A Tailor Made offer can be provided for an extended thread profile assortment.
Quick-change tool-holders with precision coolant include Coromant Capto® C3, C4, C5 and C6 (for use with 16 mm inserts), as well as QS shanks in 20×20 and 25×25 mm sizes (with 16 and 22 mm inserts). For internal thread turning, a minimum hole diameter of 20 mm (0.790 inch) is required.
