Core Bits
Concut wet drilling core bits provide excellent performance drilling cured concrete and asphalt.
Standard Series: These bits can be used in a wide variety of drilling applications, providing fast cutting and good life.
Premium Series: A higher diamond concentration enables these bits to perform well in reinforced concrete, with excellent speed and life. The "V" shaped segments help start holes smoothly.
Turbo Series: These fast cutting bits will cut rapidly through heavily reinforced concrete.
Spancrete Bits: The segments are set tight against each other on these bits, minimizing the chance of segment loss when cutting prestressed panels.

Tube Extensions
Concut tube extensions offer a quick, easy and low cost way to achieve greater drilling depths with your core bits. Our 12" tube extensions thread into either our standard or turbo style core bits, extending the tube length to the depth you require. Multiple extensions can be used together to build even longer bits.
Please note that tube extensions are not the same as continental tubing, which is heavier duty and more durable. Please contact us if you need information on continental tubing.
