Makita B-65399 Impact Gold 14 Pc. Titanium Drill Bit Set, 1/4 in. Hex Shank

They are hex shank for an impact driver, but that does not mean they are "impact rated". All of the smaller sizes are two-piece, a drill bit brazed into a hex shank. If you abuse these, they will break at the connection between the two pieces. Do not listen to these other reviews saying they break. These people are ABUSING these bits, waggling them around at max speed in an impact, probably drilling deep full depth holes, hammering them with the impact like a twisted chisel. The impact hammer should never engage with these if you're using them right. If the impact is actually impacting, rather than just spinning like a drill, SLOW DOWN. These are for CONVENIENCE & LIGHTENING YOUR PACK, so you can carry only an impact instead of impact + drill, they are not for demolition, high-precision, or mashing the trigger like a gorilla with speed cranked to max on your impact. The larger single piece ones will probably withstand that kind of abuse, but the two piece ones will eventually break. Use lower speeds & take it easy on the two-piece bits and they hold up just fine in wood & drywall. DO NOT USE THEM ON METAL. Thin aluminum is probably fine, but steel will absolutely destroy these. They are not for this. Go buy a set of m35 or m42 molybdenum cobalt HSS bits for steel & keep them lubricated. I've been using these for >90% of my low precision wood/drywall drilling handyman work for several months. I estimate around 500 holes drilled with the set, almost entirely with the mid-size two piece ones at depths less than 2". NO FAILURES, work just as well as day one. This is a very solid set at a great price. Just use them how they're intended. Stay within their limits.

strrdy case -- Makita logo -- only used some of the smaller bits for pilot holes in a wooden fence and some aluminium tubing putting out yard tirinkets -- edges are sharp -- no wobble -- clean cuts in wood -- some tear outs in the metal because they cut through so fast -- wouldn't hesitate to order again -- quite a bargain in my opinion

I had read that De Walt is slipping a bit, so went with another top brand. The Makita drills are moderately better and the case is solid, now mounted on my garage dry wall. I hadn't realized you get all fourteen drills, and was only expecting the six big ones. I thought the pic was an either/or, but you get both. At that price, it's a steal. Recommend.

Case is too flimsy, also the bits were in so tight you need to pry them out with screwdriver, tolerance is off. Still a nice set, but not up to the brand name.

Great value

These are a pretty good set for the money. I wanted a small set that went to half inch that I could use to quickly put in an impact and not have to get the drill out and get my larger set out for most jobs. Just be careful with some of the smaller bits. If you use them in an impact it's easy to break one they come with a nice case no as typical when they're new, they're kind of a bear to get out of there.

Good brand and good product

The bits that I have used so far have worked fine.

サンシェードを取り付ける金具を設置するために購入。 個人で業務用を購入する方は少ないと思いますが、我が家の壁は家庭用のでは穴が空けられないので、 今後使用も視野に入れ業務用を購入しました。 肝心のドリルが別売りのため高いですが、この純正を購入。 中々、穴が空きませんでしたが、たまに覗くと赤くなっていたので、メーカーと純正品を信じて粘り強く使い続けたら、見事穴が空きました。 安心して使用できる分、純正品は高いですが目的達成できたので、買って良かったです。

These worked fine for me.

Received in good condition, come with the calibration certificate from the manufacturer.

Aun no uso el equipo pero se ven de muy buena calidad y creo que funcionan muy bien
