5pcs 1/4 inch Hex Shank Rotary Burr Set, HSS Wood Carving Rotary Rasp File Electric Grinding Tool

its okay

I ordered these to notch small pieces of aluminum, and they come smooth. The cuts are there but but shallow and smooth. So I didn't want to deal with sending back and having to wait to finish my project so I cut the grooves deaper and at a little more of a angle to get a more aggressive cut. Took me about 45 mins to do the 3 I planned on using. Not happy with product .

I was really looking forward to getting these as they would fit into my 1/4" impact however they were very disappointed. They are so dull that they wont cut thin metal. I tried to widen a hold on a thin metal door and they would not even cut the thin door metal. Brand new and they don't cut. I have higher quality ones that don't fit 1/4 from a different manufacturer and they cut awesome, but these would barely take the paint off the door. Take my advice and find a different brand unless you just don't have anything else to do with your time but watch a bit spin.

You get what you pay for. These dull really easy, and barely can bore out MDF/particle board, let alone solid wood. Alright in a pinch, but nothing to write home about.

Not sure what the problem is but won’t cut into wood at all. Maybe I got a set that they didn’t sharpen or something. But chucked up every one of the burrs and tried to round over a corner on a scrap piece of plywood. Just sat there spinning against the wood but would not take off even the smallest corner. Will be returning

I should have read the reviews before buying this. These bits are all dull and don't cut into wood at all.
