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

Got this during a promo sale a few years ago. Just recently had to use this to drill out a broken oil pan bolt in a tight space and this was a life saver. I connected this onto a 1/4” adapter and it saved me from lowering a vehicle subframe just to drill that bolt out. Thank goodness. I might buy another set. The bit head are still sharp after a couple uses so im happy. Cant beat this fo $11.

Great set.

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.

The drill bit worked fine but when I went to pull the assembly out, the hex head separated from the drill bit shank. Not quite sure as to how I will fix it yet.

Another great addition to my makita collection! Got these so I could drill with my driver.

Great value, the 1/2 bit is specially useful for installing drywall toggles. sharp as it gets, be careful while handling. Those bits pierce aluminum like it's nothing. Makita is a superior brand, and for this price honestly is the best deal you could get.. Dewalt and Ryobi are subpar compared to those.

I like these bits so far

The 135 degree tip really doesn’t “walk” when drilling metal. The bits were perfect. Only complaint I have is that they’re difficult to remove from the case.

As expected. It is goid stuff. Recommended. A++

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

Usual Makita quality. The bits are well-made and drill fast, accurate holes. As they are titanium nitride coated they should be wear resistant and last a long time.
