Tungsten carbide tip is durable when drilling in concrete and brick. Deep single flute removes dust fast for increased drilling speed and longer bit life. Diamond ground tip has aggressive cutting angles for increased drilling speed. Fits all hammer drills with 3-jaw or Jacobs chuck.
Strong and durable. Spare bit for a tool kit (cheap). The original drill bit was used to drill a hole in a 12 inch concrete foundation. It failed before it passed. This replacement drill drilled three holes and the carbide drill still looks "new". difference between day and night.
Pros
Diamond ground tip has aggressive cutting angles to increase drilling speed
I needed to mount my workbench to a concrete block wall. I bought large rock bolts for strength and bought this drill bit to drill through a concrete block wall. I pre-drilled the wood with a regular drill and then switched to this drill to drill through the cinder blocks, which worked well and quickly, just as I expected.
Pros
Deep single groove quickly removes dust, increases drill speed and extends drill bit life
Use this bad boy to run camera cables around the house. Works amazing and goes through concrete like butter. 1/2 inch is a bit flimsy for the PoE camera cables and had to drill a few times to make it bigger. Long enough to go through a cinder block! For PoE or Ethernet cable 3/4" spring.
Pros
Fits any rotary hammer with a 3-jaw or Jacobs chuck
