BT Tool Holders

Every BT tool holder Briney makes is manufactured in the USA from Certified material and production quality is ensured through ISO 9001:2008 policies. BT tool holders are symmetrical around the spindle access giving them greater stability at high speeds. Briney’s Maximum VelocityTM tooling is balanced to 2.5 G or better at 30,000 RPM. Exceptional balance and the deepest case depths in the industry mean you get 100% more life out of our tool holders.
