This set was referred by my carpenter friend. It is pretty cool for my woodworking DIY. It has 12 pieces with 5 sizes, so I can use it for many screws. The adjustable depth is great, help me make perfect holes every time, and the magnetic extension holder keep bits steady—no slipping! It come with nice storage box to keep all organize.

This is a good value countersink drill bit set. I like that it comes with replacement bits for added value. Bits performs well, with clean cuts and smooth action. I think this is a great addition to the homeowners tool kit or a good backup set for professionals who typically use higher quality tools. Overall I am very happy with it.

I used these countersink bits in my drill press and cordless drill and they work well. The cutting edge of the bits are symmetrical, sharp and I haven't had any issues using them in pine and butcher block. The length of the bits are easy to adjust using the included hex key and the bits are able to make smooth and clean countersinks. Overall these are nice countersink bits and I like that they include a plastic storage case to keep them organized.

I'm not typically a high rater. To get 5-stars, the product has to do something to knock my socks off. 4-stars means GOOD product. The countersink drill bits are essentially as described on the Amazon site. The bits include #4-5/64", #6-3/32", #8-7/64", #10-1/8", and #12-9/64" and all were measured correctly with a caliper. They are a two-fluted design in a single unit. While they work, I do prefer a 3-flute countersink; they produce a better cut counter sink. The bits are adjustable with a single set-screw. The product does include the set screw Allen wrench and an extra set of drill bits. For the price, they seem like a good value for the money. Overall, nothing spectacular but a GOOD product so far.

While priced on the high end for five countersinks, this set includes a magnetic bit holder, an Allen wrench, and replacement bits. When the product arrived, I thought there was an additional set screw, but it was not set in the #10 countersink as seen in the photo.I work with hardwoods and softwood, and the twist drill bits with this set worked great in soft and hard species such as pine, oak, and poplar. The countersink produced no tearout on the surface and was clean on softwoods but a bit rougher on some hardwoods, such as oak.I like that you can replace the drill bits (5/64", 3/32", 7/64", 1/8", 9/64") because (1) drill bits get dull or break, or (2), I like using Brad Point Drill bits with countersinks when working with hardwoods to prevent the bit from wandering when starting a hole. The bits fit tightly in the countersink, so I am uncertain if a metric equivalent would fit (rounding up) or be off-centred to produce a wobble (rounded down).This countersink has a short counterbore to attach drill stop bit collars. Collars ensure consistent depth using a hand drill instead of a drill press. Over the years, I have accumulated different types of depth collars, and only my shallow depth collars with set screws work due to the shallow shoulder of the counterbore.

Great quality and countersink works fantastic. Some reviewers had trouble getting the bits to move, but it helps to be more intelligent than what your trying to operate!

This "Ezarc" branded Countersink Drill Bit Set caught my eye when I came across the listing. I was in need of a specific bit for a small tabletop Arcade Machine I was crafting and this set looked like it would do nicely. This seemed like a good value for a 5 Bit set vs. some I had seen at my local home improvement store and was interested in checking this out.The set comes in a transparent case which helps to keep the small parts safe and organized. The outer shell is not too thick but good enough for basic protection. The inner removeable tray is a lot thinner gauge plastic. I would liken that to about the same as you would find in retail clamshell type outer packaging.The countersinks and bits themselves impressed on first inspection. They all appear to be well made and durable enough for their intended use. The retaining set screws felt sturdy and moved smoothly when using the allen key. In actual use these bits have perfomed well for me. The drill bits easily cut into wood and the countersinks created nice clean reliefs for the screw heads in my project.Overall, I am pleased with this Ezarc set. They have decent build quality and are durable. Most importantly, they made clean cuts! I should note that I would actually call this a 17 piece kit (vs. 12) as there is one complete 5 Drill replacement set in addition to the 5 that already ship mounted in the countersink shafts. I feel the current listing price of $29.97 is reasonable for what you are getting here. I am giving this a 5 rating as it not only met, but exceeded my expectations. This kit is worth considering in my opinion.
