EZARC Countersink Drill Bit Set, 5 PCS Tapered Drill Bits Counter Sinker Set, 1/4" Hex Shank Quick Change for Woodworking, Pilot Screw Hole Set

Nice price, seems like a quality product. Only got to use one of the bits for a few times

quality appears good but I managed to break one very quickly. Seem brittle.Addendum: I originally rated as 3 stars but have changed that to 4..why? Their pro-active outreach re: my complaint was above and beyond. They replaced the whole set for free (without me asking!)..As a long-term woodworker I have to accept that things break and I have to impressed by people who really want to do better. I've also bought some of their other products and they seem to be of good quality. A for effort ..A- for product

Clean the counter sink before use and plug cutter then they are great

I gave these to an apprentice. They break everything anyway. Good set if you won't use them much

My husband loves this tool! Love that it is great for screws to be flush with wood.

Counter sink bits work pretty well and do their job as expected. I like the adjustable design, both for the pilot hole depth and the sinking depth. The downside is the plug cutter bit, especially on hardwood. It worked "acceptable" on pine which is soft, but there was a ton of burn and smoke when I tried it on beech. I could even imagine burning as the only reason the bit was still going down the wood.

Makes predrilling and countersinking fast and simple!

Excellent product. Easy to use. Conceal screws with plugs.

Test réalisé, sur du mdf color mass et du chêne résultats très satisfaisant pour un produit aussi bon marché. Juste pour la mèche à bouchon pas très pratique pour l'entame de la matière mais une fois démarrer sa fonctionne nickel.

ドリルの仕上げが少し雑で、深さ調整のリングが入らずやすりで調整したりの手間が必要になった、使用に関しては、今の所問題ないかな。

刃先の仕上がりが甘いかな？普通に使うには十分とは思いますが。

The plug cutting bit is very course cutting, it tears rather than cutting resulting in a very rough plug, so rough I could not be sure there is enough surface area to ensure the glue holds. The plug cutter requires to be used in a rigid pillar drill with the work piece securely clamped down otherwise the cutter tracks across the work piece. The counter sink bit is also course cutting leaving a rough edge to the counter sink hole. The end result is the job does not have the finish you may have hoped for. This will be going back!Since the review above I returned the item. Following this the seller sent a free replacement asking me to reconsider the review. My drill press is a cheap one which clamps a standard hand drill, despite my best efforts it is not rigid enough to prevent the plug cutter tracking sideways. I took the drill set to a local ‘men’s shed’ charity who have an old but perfectly serviceable heavy-duty drill press . They had good results and were pleased with the set, so I left them there.Given you can get good results if you have the right kit I have upgraded my review to four stars.

Haven’t used yet but look good quality
