KOWOOD Countersink Drill Bit Set of 8 Pieces 5/16" Round Shank with Adjustable Depth Stop. (Including: 2 Wrenches, 3 Small Screws, 1 Large Screw and 12 Wood Screws)

This set comes with #5 which is why I bought the set

The media could not be loaded.  This drill set is a must have for any home improvement projects. this set contains everything I need. And the quality is amazing! It’s very durable and this set would last many years!

This is a great set with a lot Of various sizes. Very sharp with a Nice depth guard. They are very precisely made and easily adjustable. These are a great value and will get used a lot.

This is a very nice set of countersink bits. They are machined well and even have carbide cutters for the counter-sink portion. The drill bits range in size from 2mm to 4mm with some of them differing in size by only 0.1mm or 0.2mm. Each bit comes in its own case. The cases are labeled but didn't include any units. For example, one bit is labeled "8 * 8 * 2". Now I know that refers to 8mm shank diameter, 8mm countersink diameter and a 2mm drill bit. Since most American woodworkers use the imperial system, not metric, it's not clear, at least to me, which bit is appropriate for which screw size. I plan to look it up and label each case myself. That doesn't diminish the tool itself so I'm not removing any stars, but it will require some time on my side to make this set useful. I'd recommend that the vendor get to know their customers a little better. A small reference sheet could have easily been dropped in each package, or better yet a laminated reference card.On to the bits... Again they are machined very well and show up lightly oiled. Each bit has a hole for two set screws: one to hold the drill bit in place and the other to attach the optional depth stop. The required allen wrenches are included as well as a few extra allen screws for the drill bits. The bits are sharp and cut easily. They make a nice clean hole. I especially like the depth stop. It attaches easily to the side of the bit and it can be adjusted without removing the bit from the drill.This is a great set of countersink bits... now I just need to go do some metric to imperial conversions.

I'm just your average guy who likes to do a few projects every so often but this has really helped me a lot already.This comes with 3 extra little screws that are extras of what are in the countersinks in case something happens to those, 1 larger screw that is for the adjustable depth stop and screws into the opposite side of the countersink, two Alan wrenches for those two screw sizes, and a dozen wood screws in addition to the 3 countersinks and drill bits.The adjustable length for the drill bits is great so I can drill the hole and countersink at the same time without having to worry about messing up my countersink. I used to just avoid countersinking and planned around that but this has really opened up some new possibilities for me.I expect that this set would make a pro laugh at it's simplicity but it's perfect for an amateur like me.What I liked about it: Easy to use and complete set with backup screws.What I didn't like: This set makes me want to buy more tools to keep improving!Overall, I recommend this for any beginner wood worker.

These carbide tipped bits last a long time and have made drilling countersink holes very easy. There are adjustable stops to create different depth holes. Easy to set up and drill perfectly perpendicular holes.

This KOWOOD Countersink Drill Bit Set of 8 Pieces 5/16" Round Shank with Adjustable Depth Stop, was an appealing product for my woodshop.I have no idea regarding the longevity of the product, as I have not, as yet, had ample opportunity to employ them. Although, they do appear to be manufactured out of a fine grade carbonized material.This KOWOOD Countersink Drill Bit Set is so small as to only be sufficient within a very limited range of versatility, e.g. finish trim work/repair.

This is a great set.They cut very cleanly and the set has a good selection of sizes.Don't be worried they are in metric. The size are close enough to imperial that this set works great for imperial or metric.Having adjustable lengths has been great; no more drilling each hole twice and the countersink is always in-line with the hole.Also, I'm no longer making the countersinks too deep or too shallow; all of the countersinks are the same the correct depth thanks to the stopper.

Nothing to dislike about these drill bits the great and go through wood like crazy.
