Left-to-right, in the case:
3/16, 3/16, 3/8, hinge, 1/4, 5/32, 5/32, short-1/8

Bosch quality, of course, so no matter how cheap your hammerdrill,
the /drilling/ should work well-enough
( bits matter more than the motor, for any given hole,
just as the saw-blades matter more than the saw-motor, for any given cut ).

For a spare-set, a second-set, an emergency-backup, or to just give to new help,
this's the best basic hammerdrill set I know-of.

Obviously, if you're doing a lot of tapcons,
you'll need the Bosch Blue-Granite tapcons drills...
they've got 'em in batches, iirc,
certainly they've got 'em in 6-packs: 3 smaller & 3 larger.

( pro tip: if you EVER want to renovate what you're putting in now,
then use tapcons, not ramset/hilti-nails:
the powder-powered nails SPALL the concrete bad, when you break 'em off.
Tapcons can be broken straight off, leaving a much cleaner ceiling/wall/floor )

The case is typically Bosch over-engineered -laughing-
if your toolbag demolishes the case before your bits die,
you ran over the toolbag with your truck, your friend's truck, and the bulldozer too!

Also, of course, being Bosch, you can stand the side of drill-holders up
( the red plastic flips up ), OR, if you prefer,
you can get just the bit you want out,
and stand IT in its perpendicular hole
( the holes we can see the shafts through, on the front of the red plastic ).

For hammerdrill/masonry bits, I don't buy any other brand: Bosch are bestest.

( for metal I buy good cobalt bits, and for wood I get lee valley HSS bits )

Cheers & HTH!

I haven't used a hammer drill very much yet, but after recently using the Dewalt DCD970KL I broke two cheaper bits attempting to drill into concrete. I purchased this set and was amazed at how fast and easy these bits drilled holes in concrete. I would highly recommend these bits!

August 18, 2011: I have used these bits on numerous occasions with my hammer drill and still, they cut quickly and without a hitch! After far more than 100 holes, the same bit keeps cutting like a hot knife through butter. Highly highly recommend.

These bits work great through cement and go through pretty quick. The only thing is that since they are round, they may catch and just spin in the drill.

I have to say these bits are the way to go. I had to drill threw stucco and broke 3 bits; including the bits that were specifically designed for stucco. Also, before I broke the bits, it took forever to drill a hole... I was tired, hot, and extremely frustrated during the process. (from home depot,the bit comes with screws precisely made for stucco).

Once I bought the Bosch bits I drilled 25 different holes in under 20 mins (w/ a hammer drill, a lot faster than normal drill). These bits are the BOMB! VERY proficient for faster and easier drilling. It may be a few extra bucks more compared to normal bits but well worth it!

I HIGHLY recommend this. TRUST THE BIGDOD!

I bought this particular set because I like to have a case for my drill bits. This surprisingly is a very nice case, that likely wont get crushed. The set contains 2 pairs of duplicated sizes (I think the sizes duplicated are the 11/32s 1/4s) this works out well as they are the most common sizes used for drilling for TapCons. If you get this on a discount I would recommend this over any other case set
