DeWalt DT6952-QZ Drill Driver Bit Set 4,5,6,8 and 10 5pcs Masonry

This is an excellent drill set for the price. I wish the will have a set with the standard and long lengths. It work pretty well but if you use it for solid concrete and brick, they will do the job but I think they won't last as long as you like too. Overall, great little set.

Great choice! Cut through concrete just like butter and bits still look brand new!

These are just as advertised. They sizes are metric (mm) which accounts for the strange numbers.

Works great

Item was just as described and shipped promptly.

Disclaimer - I'm not Bob Vila, but I know which end of a drill to hold. There are a few issues with the product that caused me problems, and turned a quick project into a really long project.1) the container it comes in is really flimsy, and the bits don't stay in their notches. They were all mixed up when I got them.2) The bits do not have hex shanks, so then I had to go buy an adapter. (Ok, that one was my fault, I guess - I thought the bases were all the same).3) I am familiar with standard and metric sizes, but even after a LOT of googling and searching on the topic, I still have NO IDEA what these size numbers mean. I can see that there is some standard for "#4" or "#5", but I can't make any sense of it in the context of my project.The takeaway: Only buy this product if you are a HIGHLY EXPERIENCED PROFESSIONAL. Otherwise, unless you like making guesses about hole sizes, these drill bits are pretty useless.

Great quality product delivered quickly.
