Would RecommendIt drills a nice clean flat hole but it is slow , every drill bit whether spade bits forstner bits their slow but they make a smooth hole. I'm making a project that needs smooth bottom holes.

Not good if you’re looking for something precise
Would Not RecommendBought two of these at the same time and the diameter of the holes drilled by the bits are off by about 1/8” from each other.

Size is incorrect
Would Not RecommendWhile I genuinely like Irwin products, this one was extremely disappointing. The size was off by 1/8” dispite being label as 1-3/8” 34.9mm. The actual measurement was 1-1/4”. Others on the site verified the mislabeling, both on the package and the incorrect marking on the shank of the forstner bit itself. Just wish I checked before I set up my cabinets work. Going to another place tomorrow and buy another brand. Can’t trust Irwin any longer. PS: IRWIN Customer Service, please don’t ask m...

Maybe ok for soft wood but not for hard wood
Would Not RecommendDrilled 14 1/2" deep holes in oak which went ok as long as you are patient. Had to sharpen the bit to get through 7 more holes. Have been unable to adequately re-sharpen to continue using it.

The item matches the description
Would RecommendThis is a good product for the price, the blades dulled relatively quickly which is why it’s always better to buy more than one fostner bit. I haven’t found any better brands yet. This has been the one to last the longest so far!
