I need to drill into the end grain of a 4x4 block of pine with a 2" version of this bit---how well does this bit perform on this material?

Asked by: Mike
Thank you for your question. Our Multi Construction hole saws would work well for your application. These holesaws have diamond ground carbide teeth for fast drilling into wood and other materials.

Customer Reviews

2-9/16 in. Carbide Multi Construction Hole Saw for Wood, Metal, Masonry, and Fiber Cement is rated 1.3 out of 5 by 3.
Rated 2 out of 5 by from Maybe engineering tolerances have changed We've used these hole saws for a couple of years for our plumbing business. We have multiple sets. They are awesome when they actually fit together. Recently we've purchased new bits and mandrels at a big box store and have found that they are difficult to attach. The pilot bit falls out of the mandrel and the hole saw will not fit over said pilot bit. We had to file the pilot bit and the base of the hole saw to get everything to fit together. Considering switching to a competitor's product since this happened on two of the last sets we've purchased.

Rated 1 out of 5 by from Toothless in Michigan Bought drill and mandril for drilling through cement blocks. Had two holes (four holes in 1" thick block sidewalls.) for two 1-1/2" conduit penetrations. Drilled very slowly. In second hole (far side of first hole) one carbide tooth fell off. In third side, last three teeth fell off. Well, three teeth fell off, one tooth broke off leaving small piece of carbide behind. I was told by store that this was best available for cement blocks. The mandrel and pilot drill did not fit together. The drill would not fit into the hole of the mandrel adapter. I had to drill hole larger for drill to fit. After drilling my 3 holes, I had trouble getting the mandril off of the drill. I cannot get the pilot drill out of the mandrel adapter. I guess I leave it in until it either wears out or the carbide tip falls off. Then I guess I'll either have to pound it off or work some lubrication in there but then it would attract the cement dust and I'm sure it will not come off a second time.
