Bosch Impact Tough 40-Piece Drill Bit Set Accessory Reviews

Bosch Impact Tough 40-Piece Drill Bit Set


It never fails – I’m walking down the tool aisle of a store and have to stop and stare at the accessories. After all, who knows when something new might show up? While I always need #2 Phillips bits and a couple sizes of Torx, I typically pick up sets that cover some of the other oddball stuff I run into. With Father’s Day right around the corner, this seems as good a time as any to consider the Bosch Impact Tough 40-Piece Drill Bit Set.

Bosch covers the majority of needs for Pros with a combination of Phillips, square, combination, and Torx bits along with a nut driver/bit holder and selection of 8 drill bits. Here’s a little more detail about the contents:

Field Notes

One of the things I really like with this set is that Bosch makes each of the red trays inside removable. It’s a small touch that makes accessing the bits easier or lets you carry just what you need instead of the entire case if space is an issue.

The black oxide coating on the drills bits gives them some extra lasting ability for general purpose drilling without driving up the cost. With the two smaller sizes (1/16″ and 3/32″), Bosch gives you a spare since they’re the most likely to break on you.

I also like the included 2″ power bits. These are more convenient to use in an impact driver than 1″ bits that need a bit holder. They’re more expensive since they take more material to produce and have a longer Torsion Zone, so the luxury is a nice inclusion.

Pro Tip: While you can use impact-rated bits in both an impact driver or drill/driver, it’s not usual for a standard bit to outperform them in wood fastening applications. Impact bits do their best work in metal fastening where absorbing the shock is much more critical.

Price and Value

Priced right at $25, there aren’t any surprises. The set is a little less than the gold standard and a little more than the value brands. Realistically, it’s a good price from a brand that knows accessories. The set makes a great gift and is priced at a point that you can pick up one for yourself, too.

One other quick note about buying bit sets. Most Pros have their go-to bits. The value of a set like the Bosch Impact Tough 40-Piece Drill Bit Set isn’t that you’re getting something you don’t already have, it’s that you can put an extra general purpose set of bits in your tool bag, toolbox, trailer, or truck so you know there are always accessories available in case something happens to the others.

Bosch bits are by far my favorite “value” bits, I’ve used what seems like everything and the only bits I like better are Zephyr which cost a fortune.

Have the 48-piece driver set and I’m very happy so far. They have held up better than the DeWalt impact bits I had previously. I also got some Makita Impact X bits so trying to test them all and see which I prefer. Where I live (The Bahamas) we rarely see anything other than #2 Philips, so that’s most of what I use, but having the occasional torx is useful. Although I can attest I have never seen a square drive in person! For the price, I think these Bosch bits are top notch, I am considering getting a set… Read more »

Just once I would like to buy a bit case that actually held the bits in place…..not one, by any and all companies has ever kept the pieces in their perspective holders….sad.
