wesleydrill Countersink Drill Bit Set 5 pcs 82 Degree 4241 HSS High Speed Steel Fit for Sink Holes into Most Machinable Metals, Plywood, Softwood, Hardwood, Fiberglass Plastic, Mild Steel

I’m using mostly for wood and soft metal, works good. Love the case, stores in my drill kit very well and can find it easily especially when I’m at my work bench

It finally arrived. But bits are loose inside the case, and the top acrylic plate has been cracked. This is due to the poor packaging. The clasp does not engage as well. All the bits are of good quality, and it looks very sharp. But one of the attractions of this item is the case. It is a shame that it arrived damaged.

I found that these bits worked very well on the aluminum trim I made. A little trial and error on the speed and depth, but I am very pleased with the quality of the bits.

They work as intended and come in a nice case. Have only a limited time with them to rank durability or longevity. On the other hand these cut the counter sink holes fine in pine and oak boards as well as plywood. Some teapot in the plywood but the oak and pine were clean cuts

The box which these were contained within was very sturdy and helps when being stored.The bits were sharp and cut well. I really like the ability to swap them in and out quickly with the quick-disconnect.Overall, I'm very pleased with these pieces and would recommend them.I'm not a high production capacity shop, just a small time fabricator, therein, these are perfect for the price and function.
