Coolant Ring Technology (CRT) holders from Scientific Cutting Tools 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 company says. The overhang of the tools used with the holders is infinitely adjustable CNMG Insert rather than fixed, allowing for maximum performance without chatter or other performance-related issues.

The CRT holders can be used in conjunction with the company’s qualified boring bars and/or qualified threading tools for quick change machining at optimal performance Carbide Milling inserts levels, according to the company. 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 the CRT holders for quick-change setups or with our QHC holders when a backstop is used (sold separately). The CRT holders used in conjunction with the qualified boring bars have the advantage of more effectively delivering coolant to the cutting edge.
