CTR™ • Counterbore

Features and benefits

  • CTR Counterboring Tools are designed for high-production screw head counterbores and similar counterboring operations.

  • Extremely unequal insert positioning and flutes.

  • S2 S inserts reduce additional drill operations to achieve a precise 90° bottom.

  • Counterboring tool shipped with insert screws and Torx wrench.
