Customer Questions & Answers

will this fit a 3/8th in chuck? This seems like it should be on the spec list.

Asked by: fred
No, I had to use my half inch drill with it They might make a version which fits a 3/8 chuck, but the one that I purchased in the store did not.

Rated 5 out of 5 by from milwaukee is the way to go I have been buying Milwaukee blades lately after noticing that Dewalt blades were junk. So, I needed a drill bit and ran up to home depot to get a good one. I was going to get the Milwaukee first, but that shiny Dewalt titanium precision bit lured me away. So I bought the Dewalt which drilled the first two holes perfectly, then broke as I began to drill the third. I took the Dewalt back to the home depot for a refund and purchased the Milwaukee like I should have in the first place. It drilled the remaining six holes through 1/4 steel without issue. This is a good bit, and just what I have come to expect from Milwaukee. Side note: Not sure what they guy with the negative review got, could have been a lemon. I drilled six holes in 1/4 plate steel with no lubricant, and it cut like a hot knife through butter.

Rated 5 out of 5 by from 9/16 inch dril bit I build a number of wooden toys that I sell and this drill bit was used to make holes to connect certain parts together with dowel pins. I have all ready used this bit to drill several holes in both soft and hard woods and it always produced a clean smooth hole.

Rated 1 out of 5 by from Chinese junk! Would not even drill through 1/8" mild steel plate, on a drill press, with oil and the proper speed. If I want to buy Chinese junk I can go to Harbor freight. Now it will cost me hours or days to find a real bit!!!
