   High quality, low cost
   These are extremely high quality countersinks. I was surprised how well they cut hardwood for a low price.

   Good Quality
   Past experience had led me to try to avoid buying any item that “cuts” from China. That includes chisels, Forstner bits, drills etc. Performance has ranged from mediocre to worthless. EZARC Countersink Drill Bits are none of that. Out of the package, immediately it was obvious the machining and finish on these countersinks was good.When chucked in my drill press and with the press turned on, I noted that the drill bit in the countersink ran very true with no wobble or runout. I did not see any misalignment with the chuck and had no problem positioning the drill at the marked spot on the wood. Cheaper sets wobble so bad it’s hard to find center.I tested on Poplar, Walnut, and 125 year old white oak and the result was a very smooth countersink and though the oak was extremely hard, the cut was clean with no burning.Being a retired machine designer and engineer I am no stranger to machining processes. Final verdict is that the money was well spent, I do not regret buying this set, and will put it to good use. Not my place to tell people to run out and buy them but you could do a lot worse buying a cheaper brand.

   Sharp and precise
   This is a good set. Comes with extra bits. The countersink part is sharp. The screw holds the drill bit in place.All of the bit sizes are small, I don’t know if they make a larger set. If they do, I will buy that too.Will buy again.

   Great tool
   Purchased these rather than drill and changing to a counter set bit. These drill the right size hole and counter sink in one motion. Nice plastic case to hold the various sizes. I like them.

   Great for DIY’ers
   These have come in handy so many times. I don’t know why I waited so long to buy these.A few projects I’ve had I wanted to hide the screw or make the edge flush without a metal screw sticking out.Great little kit for any diy’er.

    I think these countersink drills are excellent value for money. Before drilling just make sure the grub screw is fully tightened onto the drill shaft then they work perfectly and save time.

    問題なく仕事してくれます。あと1センチぐらいドリル部が長くても良かったのかな、とも思いました。
