Speed Diamond Core Bits - Pro Grade for High Strength, Heavy Reinforced, Heavy Aggregate Concrete.

Speed Core Bits

Heavy Reinforced Concrete

12" Tube Extensions

Pro - Turbo Segmented Rim, Wet Drilling, X-Fast Cutting.

Speed Core Bits
Very Fast
&
Deeper Drilling

Drill Deeper than 12" Holes

Extension tubes are available for bit sizes: 1" - 6-1/4".

The end-cap of the Speed Core bit (with the 1-1/4x7 hub), threads off and the extension threads into it. The other end of the extension (with an internal thread) accepts the previously removed end-cap or additional extensions.

STRAIGHT-WALL SPEED CORE BITS
Combination of Segmented Turbo Diamond Segment plus Bond Matrix and High-End Diamonds provides Aggressive, Fast Coring.

Superior speed and life through a wide range of concrete hardness and reinforcement
Used by mechanical contractors nationwide who drill 100's of holes daily
Laser welded for superior life
Favorite choice of concrete drilling contractors --- Very fast drilling under any circumstance
Specifically designed to drill through high strength, heavy reinforced concrete & hard aggregate
Design provides extended bit life and faster coring
Wet Use, 10mm (.395") Diamond Segment Height.

Removable 1-1/4"-7 Threaded End-Cap: With the end-cap (arbor) removed, install multiple 12" extension tubes for deeper drilling.

The extension tube, with an external thread, threads into the bit; it's internal thread accepts the removed 1-1/4"-7 threaded end-cap or additional extension tubes.

Precisely machined from high-tensile steel, these premium extensions are built to withstand extreme industrial torque while maintaining perfect concentric alignment to eliminate bit wobble or vibration.
Designed to integrate seamlessly with the Speed Core Bits and its removable end-cap, they install quickly between the barrel and the cap assembly to ensure deep-hole penetration through hard concrete with reinforcement.
Available in 12" lengths, multiple extensions are connected together for the deepest hole.
