Ratings & Reviews for Kobalt 4 -Piece Assorted x 1-5/8-in Woodboring Countersink Drill Bit Set

Good so far

Items have worked as they should. Would recommend.

Great offsets

Exactly what all woodworkers need so you can countersink screws and nails so your wood will not crack.

good quality, good price

i lost the previous ones i had, lasted me years, same brand, same ones. i use them for drilling in pine, oak, walnut wood, previous ones never went dull with years of use, which is why i bought them again.

Countersink bit set

I had watched a video on YouTube of a gentleman making drawer boxes and using some of these countersink bits. I purchased a set and built the drawer boxes.I was totally blown away at how well they performed and inhanced my project. They lock the boxes together very tightly and make the whole job look so professional. I will be using them in further projects.

Poor mateiral, broke on first use

On first use of the product, in hard wood, the drill broke off at the counter sink. Poor material used in making the product. Don't but unless you plan on using in pine or other softwood.

Hex screw doesn't grip tightly

My No.10 hex screw got hot and allowed the drill bit to slide the first day i used it. I have not used other sizes as much to see if they loosen with multiple use. I may opt for a higher quality bit.

Not the fanciest, but they get the job done...

These countersink/counter bores will get the job done. They don’t work as well in hardwoods as the tapered bits, but they work just fine in softer wood and plywood. The price difference is considerable, with the set of 4 sizes costing less than a single tapered bit. Definitely worth it to have these!

Not sharp!

I had Stanley like these decades ago - Kobalt was horrible and did not cut well at all, they burred the wood. Do not recommend. Misplaced the receipt, or would have returned them...

Wobbly countersink drill bits

The countersink bits works alright, only the drill bit is not completely straight.
