3" X 14" Wet Diamond Core Drill Bit with 1-1/4"-7 Female Head.
Our Builders Depot® Core Bits have laser welded segments containing the highest quality artificial diamonds and have been specially formulated to offer the best performance in most materials.
Supreme quality diamond bits are the preferred choice of professional concrete coring and drilling contractors, and are designed for medium to large sized jobs where cost per hole is important.
The supreme bits have a greater amount of high quality diamond in the segment, which provide faster cutting and longer life. Laser welding helps prevent segment loss.
Special lengths are available and can be shipped within 24-48 hours.
1-3/4" diameter and smaller coring bits have a 5/8"-11 built in head. 2" diameter and larger coring bits have a 1-1/4"-7 built in head. These bits are compatible with all standard core-drill motors including, but not limited to: Core Bore, Milwaukee, Weka and Eibenstock. We stock adapters so you can use our bits on Hilti Core Drill Machines.
This bit is designed to cut the following materials: Block, Brick, Concrete, Critically Hard Concrete, Cured Concrete, Green Concrete, Hard Aggregate, Hard Brick, Hard Concrete, Masonry, Pavers, Reinforced Concrete, Soft Aggregate, Soft Asphalt.

- concrete bits Review by buggz

I have used the concrete wet bits from Builders Depot over the years and I have also had to purchase several other brands in between orders from BD. For the money you will not find a better bit anywhere. The cutting teeth stay on the barrel unlike the other bits I have used. Great quality at a great price. (Posted on 5/9/2017)
