“The core drill I bought worked well but I was unaware that a pilot bit did not accompany each drill bit.. I would like to see all those products listed on your web page so they can be purchased together.”
“Ordered a 2"-4"-6" Core Bits. They are well worth the purchase price. 4" Bit Cored 8" Concrete (hard stuff) just as well as bits 3 times the price. Have not used the 6" yet but expect it to perform well also. The 2" Bit on the other-hand had a hard time. Drilled 10+ holes with it and the core kept breaking inside the bit causing me to stop and fish out a 1-2" piece of concrete every few minutes. I don't think the 2" Bit was Uniform in circumference and that's why it kept breaking the core off inside of it. Turned a 2 hour Task into a several Hour Task and a Mess to clean Up at that. Would I recommend these Bits. YES! I think I just got a bad 2" Bit. The 4" Bit cut through with ease. Well Worth the Money and I'll be buying more.”
“Excellent. Except my 7"pcd cup wheels broke quicker than my other brands. I just ordered two more and a bunch of other cup wheels and shrouds. Those worked great and I will see how the new pcd's hold up.
Thank you,

“I drilled 64 holes in varied concrete. Most in precast single rod 3/8" reinforced steps at a school. Holes size was 4"w x 6"d . My average drill time was 35min per hole. The best speed I got was when I used a thick thick slurry. I used two bits for the job. A consistent strong anchor for the drill base is the key to speed. I used a Milwaukee vacuum pad and 1/2" expansion anchors depending on location. This was my fist core drill job so there has been a learning curve but for $80 I don't think it get much better in the durability of the bits, both still have over half life. On the next job Im I'm confident in biding the time required at 45min per hole. There was no hired help operating the core drill it was all me. Thanks EDiamond!”
