Surprisingly good for the price (£5.09), cuts well and looks to be good quality.Can cut up to 50mm deep, maybe a bit more if you really need it (the shank is 80mm)For the most part cuts were clean and easy to make as long as you start slowly and don't overload the bit you shouldn't have any problems.Would definitely buy again and will be buying more sourcing map drill bits in the future.

For the price ( I've only got a small workshop) this forstner bit is Very good. Just done 20 holes holes and no problems. Cheap and does the job. Will buy again. 9.5 out of 10👍

Quality seems fine, but accuracy is not great if you are going to use it on hand drill. Tried it with my dewalt drill with free hands. Accuracy is good on 18mm OSB sheet. However, the accruracy was not very good on 2' x 4' treated timbers. The product page already mentioned it's not designed for hand drills, so keep that in mind if you still want to try.

Was slightly apprehensive about the quality of this drill bit, but after having cut a few holes, it seems to perform very well. Close inspection of the TCT cutting parts reveals it's less expensive origins, but it is constructed reasonably well. The side cutters are positioned slightly squint, but in the final grinding stage, this is compensated for. There is 20thou run-out on the shaft, however, only 5 thou run-out on the side cutters. It cuts quite clean, some slight cross grain tear out on pine, but cut very cleanly on oak. Sides of the holes and top edge are very clean. Hole size was quite accurate, within .2mm. This tool will not get heavy use, so should be fine for me. Hopefully it will continue to perform well. Overall, I am very happy with the performance of this bit, but I have only cut a few holes so far.

Yes it's a drill and it cuts nice accurate round flat bottomed holes in wood very nicely and very easily just like its desgned to do.

Works very well, smooth cut (in plywood) so happy with purchase. Didn't clog and was easy to keep control of. Time will tell how long it stays sharp but for the price it's not bad at all.

nice product

Worked well for the minor job I used it for. Making some holes in rough builders timber for garden projects. If you want to get it to work finer on your projects it would need to be in a drill stand. Higher known brands would cut cleaner but it did my job.
