I have tried about every blade out there and these seem to be top shelf. I'm not gonna say they are the best but i will definitely be purchasing more.

Oh, let me tell you about the incredible Diamond Cutting Wheel! This tool defies all expectations and cuts through metal like a hot knife through butter.

28 year old Deck and side deck. I keep up with maintenance. Counter sink bits worked great.
John M. 5/5 Verified
Brilliant product. These countersink drill bit set performs really well. They stay sharp and give a nice even countersink. Easy to setup and Ezarc even provides an Allen key to adjust the depth stop. I would thoroughly recommend this product.

15/24PCS Countersink Drill Bit Set with Storage Box
Store owner replied: We love hearing this—thanks for the review!
This set has several size taper bits for pre drilling along with counter sink collars that are adjustable as to when they engage the material. Also has a couple extra bits for the smaller size. The case everything is in is pretty handy, hope it lasts. Most hard plastic cases I've had crack and break early in their life

They come in a nice case that looks sturdy. It should hold up if you don't hit it with a hammer. All the bits come out easily and go in ok too and are held there firmly. The countersink bits are very well made. I tested one on an old 2x4 scrap and it made a very clean hole. I tried the T25 Torx driver bit with a #8 deck screw and it worked perfectly. The bit holder with magnetic retention works well and is perfectly straight, no runout (no wobble at all).

So not sure why it came with several wooden dowels. The case is nice, the drill bits do work. I had wood stuck in the outer part of the bit for the wider drilling part that I had to clean out. But the bits work, so overall good product.

Wrong item sent. Will never use this vendor again.
Darrin F. 1/5 Verified
I have two sets of these drills and have used them on a regular basis. I love the tapered drill bits and the sharp countersink features. Unfortunately when using the smallest diameter drills I have encounter them breaking. One broke in use and the second when the whole drill dropped from my hand onto my bench. The latter was probably my fault but it did make me question their robustness. Regardless of this I still love Ezarc tools and will continue to buy them.

After the item being lost in the post the service I got was second to none as a replacement was dispatched to me straight away with no fuss. I would highly recommend this company.
