ToolocitySCB0300D 3-Inch Monster Dry/Wet Diamond Granite/Concrete Core Drill Bits/Hole Saws

Drilled 10 holes with itNo problems

The media could not be loaded.  Item Arrived before time schedule and as described.It worked great. I read some reviews about the time (about 8 minutes) to make a hole and I was prepare for it. I took about 3 minutes with no water, just cool off the bit average every 30 seconds.I made 3 holes; product performed well and I know I can make 30-40 more.Very Satisfied and will definitely Recommend it.

Worked very will

Needed hole through through some unusally hard grout for a 2"plumbing fitting. Did a great job. It would have done it dry but I chose to push it a little harder and keep it wet and it did a great job with no noticeable wear. 8"wall.

Smaller than advertised !

Was able to drill about 90 holes in cinder block. Could have done a few more but the 1/2" adapter I purchased separately had a little wobble to it. Drilled fast, very happy with the performnce

Two 3" holes were drilled quickly through a outside concrete slab which was poured some 50 years ago. I drilled the holes and I am almost 92 years old.

Very well made
