    • Great product
Size: 1/8 to 3/4" Material Type: Tri-Flat Shank Style: Straight
Much less than what you will pay at a big box store and works great! I used it to drill cone shaped holes in pressure treated wood to insert wire vices for my grape trellis and it went through them like butter.

It did what I intended. The oulley was frozen onto power steering shaft. I had to gring it off!

    • works for what I need it for
Size: 1/4 to 1-3/8" Material Type: Tri-Flat Shank Style: Straight
I use this bit generally for plastic (ABS, UHMW, and HDPE mostly). It cuts cleanly and effortlessly. I had purchased one in a smaller size about 5 years ago and used it daily but the last straw for that one was cutting a 3/4" dia hole in 409 Stainless steel. Stainless is hard on bits, that one included. I wouldn't recommend it for that type usage. Aluminum is fine, I have cut plenty of aluminum with it. Mild steels are generally ok to cut too so long as you use PLENTY of lubricant and keep the heat to a minimum. Please note that your cutting speed will have to reduce when you cut larger holes, the heat will destroy the bit and sometimes the part if you try to drill too fast or feed it into the work piece too quickly. ... show more

For the price there’s good. Get about 6 months of use out of them . They don’t last as long as the Lenox or other pricey ones . But get 5 bits , 3 are the most used . I try to only the big bit after starting with the smaller ones

Able to enlarge three holes and drill a hole on my 2023 Toyota Camry for hitch installation. Very strong steel for the price.

    • Specialty bit
Size: 1/4 to 1-3/8" Material Type: Tri-Flat Shank Style: Straight
I needed to enlarge an existing hole in a stainless steel sink for a dishwasher air vent. Using a conventional hole saw was not going to work as I had no center. This was the perfect bit for the job. I just used some light water, and sprayed the bit as I drilled. I was getting metal shavings, so I can say the bit was cutting, not just burnishing. I used a fairly slow speed on a half inch drill. Worked perfect for my application. Do I think this bid could drill holes all day long in stainless? Absolutely not. If you have a few holes to do though these are probably a good value. I'm sure I can get a few more uses out of this as I only used one size. There's plenty of times where I need to enlarge a hole as I was off the first try, and these bits are really idea for enlarging an existing hole. I can't think of any other bit that would work as well. It's kind of like an EZ-out. When you need it there's not much else that works as well, and I think that's the case for this bit. For me, it was the perfect solution. ... show more
