The New CRT Holder:
The CRT holder is designed with Coolant Ring Technology to create a ring of coolant around a non coolant-through tool. An ample supply of coolant surround the circumference fo the boring bar, enabling coolant to find the path of least resistance and access the bottom of the bore.
CRT Holders are made from high quality heat treated steel and come with a black oxide coating. They are engineered to allow for better coolant penetration deep into the bore, reducing temperature at the cutting edge. The overhang of the tools used with the holders is infinitely adjustable rather than fixed, allowing for maximum performance without chatter or other performance related issues. Use the CRT holder in conjunction with our qualified boring bars and/or qualified threading tools for quick change machining at optimal performance levels.
The CRT System: CRT Holder + Qualified Tools
SCT’s qualified boring bars have an overall length that is qualified to +/- 0.001 and a minimum bore diameter that is qualified to +/- 0.0005. They can be used in conjunction with our CRT holders for quick change set-ups or with our QHC holders when a backstop is used (sold separately). The CRT holders used in conjunction with our qualified boring bars have the additional advantage of delivering coolant to the cutting edge more effectively. Since the CRT holder comes standard with a backstop, SCT qualified boring bars and qualified threading tools become a complete quick change system.
