7Pcs Woodworking Countersink Drill Bits, DRILLPRO Woodworking Chamfer High-Speed Steel Countersink Drill Bits Set With One Free Hex Key Perfect

These are an alright set of counter sink bits. You get what you pay for here. They feel real cheap, they dont lock in place very well, and aren't the best quality cut. I got them cause I wanted a quick cheap set of counter sinks, they will do til I can afford to upgrade, but I dont think they will last long.

These drill bits countersink bits showed up on time. I started using them and notice that the Allen head bolt in the countersink portion of the drill does not hold up and the counter sink slides up the drillbit to the drill. I'll use them until they break and that's about all I'm ever going to get out of them.

These are huge. Not sure I would ever need to predrill holes this big.

Good product at a good price.

i do a lot of woodworking and don't have the greatest budget and these are great for the money.

Good quality and can be used with other metric or standard bits. Very good value and easily adaptable to verying projects.

Great design, but the two smaller bits were bent and run out bad on my drill press. I guess you get what you pay for.

I was able to use these over the weekend to finish my project.. they fit my drill with no problem at all.
