I used this hole cutter to drill (4) 1 1/4 cross holes in an eight inch diameter sch.80 pipe and the tool worked beautifully. Fast cutting with minimal pressure required and relatively good surface finish. The center ejector spring also work really well and I never had to stop to remove the material plug from the cutter. Having worked in the cutting tool industry for 33 years I can state with confidence that this is a great tool, especially considering the relative low cost for a carbide tool of this quality.

I was very amazed at how well this drill bit cuts through metal. It's just like the video. Use enough cutting oil and it will last a long time. I put 30+ holes in 1/4 - 1/2" steel plate and the last hole was as easy as the first. I wish I had more of these bits other than the 2 sizes I bought.

This little sucker has bored through probably about 16 inches of hot-rolled steel in total and it still gives nice long slices of removed material (bits tend to chip when they get dull). I would buy this again in a heartbeat for anyone who needs to cut steel. The metal I am cutting through already has a rough hole put in by a CNC plasma cutter, so the centerbore bit isn't getting a workout, but those carbide teeth sure are.

I needed to drill precise holes in 1" tubular stainless steel and make sure I didn't have any colateral damage. A regular bit this size chatters so much that it made it difficult to get clean holes, this solved that problem.

Wow ! This bit is amazing. I spent two hours with my small drill press and ruined several new drill bits trying to make two 5/8" holes in angle iron before giving up and looking for another way. The next day I watched a few youtube videos and discovered these hole saws. The bit arrived in two days (love Amazon Prime) and within 15 minutes was in the drill press and making perfect, effortless holes. It goes through 1/8" angle iron so quickly it barely gets hot. For drilling larger sized holes, the is the only way to go. Only wish I would have discovered these years ago !

I use this same brand and number all the time. But in this case the teeth came out prematurely on several units. Usually we drill 300-500 holes in .120" thick and .188" material as well as some .375" before we loose one tooth if at all (medium feed / pressure with ample cooling and oiling) and the continue drilling at least the same amount until the second tooth pops.

On this batch 2 teeth popped on all units around 200 holes or so. Two teeth gone and you get chatter and a goofy hole which does not work well a commercial product. 5 Stars on all my other cutters purchased at about $10.00 more locally. Another brand with four cutter is holding up O.K. to date but have not put it thru the paces yet.

I needed to drill a hole through plate steel for a "box bolt". This was great. Perfect hole, sharp, And went through the metal without any wobble or problems.

A little expensive, but I guess that is what you pay for quality.

You won't believe how fast this thing cuts. My big drill press was down so I used my spare cheapo drill press and it still cut rather well even though the drill press lacks power. This one is working out well for me, cutting 3/16" steel parts. The spring really kicks out the center piece better than I expected.
