    • This Coring Bit REQUIRES periodic Sharpening

    • Extensive use of this Coring Bit on softer materials will result in a shorter lifespan

    • To maximize this Coring Bits lifespan and cutting quality, we recommend using it on a Variable Speed Grinder. Due to the wide variability in material densities on the market, a Variable Speed grinder allows the user to adjust speeds on a project to project basis, ensuring the best possible results.

    • Although this coring bit is designed for both Dry and Wet Use, for sizes smaller than 12mm, it is recommended to use a water feed, to enhance the Coring Bits lifespan.

    • For optimal use, please refrain from applying excess pressure. The coring bit is designed to work its way through the material with minimal effort. Added pressure will often do more harm than good.

T-Slot Segment Design

The T-SLOT Segment is a feature that we added to this Industrial Grade Coring Bit to maximize it’s durability. By welding one of our T-Shaped Piranha Segments into the inserts on the coring bit frame, the PAUCM is able to withstand higher speeds, and more force, than most other coring bits on the market.

Compatible with Extender

The PAUCM can be mounted on both a 3” and 6” extender accessory, that allows to coring bit to reach even further than ever before.
