I needed this 30 mm bit to complete a router sub-base that could accommodate Porter-Cable type guide bushings. I received it very quickly and it was exactly as advertised. The bit appears well-made and is very sharp: it easily handled cutting an accurate hole in cast acrylic. I would highly recommend this bit for anyone needing accurate 30 mm holes.

This is a great drill bit. Shaved the wood into the most delicate fine bits, and it made a wonderful clean pocket for my hinges.

Works very well. It doesn't matter the wood; Purpleheart, Mesquite, Walnut this bit cuts right through it cleanly.

I was making 1/8” deep holes for a small glass. This bit worked very well giving a nice smooth bottom to the hole. Very little sanding required. Pleased with results.

Excellent - sharp - drill bit - HOWEVER beware that when not using a drill press - but instead using a hand held drill - use slow SLOW speed and maintain hand absolutely fixed. Any additional pressure [frustration with the slow going] results in binding and cutout. Control you hands / speed and boredom with slow going and it performs exceptionally.

I ordered 3 different brands of 40mm bits like this one. I use them to make holes in candle holders for my Etsy shop. This is best one by far. Stays sharp a long time, and I am drilling into hickory, oak, ash, hard maple etc.Haven’t had great success resharpening, but you get a long run before it dulls and needs replacement. For the money, best 40mm bit I have found.

I bought this bit to make 48 1/2" deep holes in red oak. Running in my drill press at 620RPM, the bit cut nice, smooth holes for the entire project. The last hole came out looking as good as the first! Then I ground the point off (which took a long time - these bits are HARD!) and went another 1/4" into each hole to create a flat bottom in the hole. This bit performed as well as name-brand bits that cost a lot more. I will definitely purchase this brand again when needed!
