CORTOOL Hex Shank Forstner Bit Set Multi Sided Shank Wood Drill bit Set (16PCS)

Needed to make a couple of through-holes in a marine plywood cabinet to mount 12v USB power outlets in a camper. I've spade drilled and jigsaw cut this plywood before and well, it didn't turn out to good. I've procrastinated ever since. But the need did not subside so I pulled the trigger and bought the CORTOOL Forstner Bit Set 16Pcs Hex Shank, Wood Drill Bits Set. Proper tool for the job. Makes great holes or countersinks if you don't go all the way through. In my case, I needed to go through and did not have access to the back side with my drill. The hole cut clean and there were no splintering. Emboldened, I'm now going to take on those other projects that need clean holes. Nice case, oiled bits, sharp, clean cutting bits, good size selection and good price.

They get the job done!

I have only used this product a few times, and I have found it to preform very well. It cuts thru a board like a hot knife thru butter. I recommend it!

I opened and test cut with every bit in the set, using a piece of red cedar.They all cut smoothly and left clean, untorn entries.They all, except the smallest, cut oversized holes; 0.2mm to 0.6mm over, well within woodworking standards. I did not think that was bad at all, considering that they are driven by hex shanks. A hex shank does not contact the jaws of a chuck in the same way that a round shank does, inducing more runout.If your picky about getting an exact hole size, I would suggest buying bits with ground round shanks, instead of bargain bits.They all had some small burrs on ground edges, nothing big and easily cleaned up.
