Whats the best bit for breaking up a six inch concrete pad with the Bosch 11240?

This unit is a light weight unit best for smaller concrete jobs 2" - 4" and stucco. For thicker concrete I would use the pointed bit, not the spade bit.

A backhoe with a pneumatic hammer! I have the HS1916 chisel and it works really well, but 6" is pretty deep. Might be ok if the pads not too big an area.

Use a utility knife and go around the edges of the knock out piece you want then use a plier to take it out bending it back and forth. I didn't know how to do it either and had a tile guy show me how to do it. ; ) It works perfectly that way.

Any bit set that has 1/4-inch hex would work for this - Im sure Black & Decker also sells bit sets. Keep in mind that this works better as a screw driver than a drill so not recommended to find drill bits larger than 3/16".

I have a crafstman on it now, but I am thinking to get a Dewalt, both will work just fine, specially with a 1/e " bit

The Bosch certainly has enough power for the job - the trick will be getting the correct blade to do this. I would see if you can find a diamond grit blade (I've seen these for cutting tile) and be sure to take your time. The dust you generate with this cutting job will also be quite hazardous to breathe in - so be sure that you have a proper dust mask!

Suggest contacting Bosch to see if they have one. Otherwise, probably would buy a cheap spade drill set from Walmart , thow the bits away and use the case.

Idon't know about Bosch's triangle shaped bits, but they should be 'Hex Shank' to fit rapid load holder.

I made my own tool. Take one of the bits (say, the pointed one), and cut it off about 4" beyond the part that goes into the drill. Throw away the pointy end. Now, buy a 3" piece of steel 3/4" pipe. Either black or galvanized will work, but black is half as expensive. Screw a 3/4" round floor plate onto one end. This will be the tamping end. Or a 3/4"-1" FPT/FPT adaptor, 1" close nipple and 1" round floor plate. Take a 3/4" coupling and screw it onto the other end. The cut-off end of your tool will fit nicely into the open end of the 3/" coupling, it's a tight fit, but it will pond itself in. This tool will all last for about 2 hours before one of the steel pipe parts breaks, but so what? It's all pretty cheap, and the cut-off tool part will last forever. I used this to tamp soil back under a sidewalk I had excavated under. Worked well. I also took a piece of hard steel, 3-1/2" x 8" x 3/16" and bolted it to a 3/4" floor plate. That worked even better.

Hello Cheryl, Thank you for asking about our Dewalt drills. For concrete and masonry, we believe any of the Dewalt hammer drills would be able to use a 1/2" bit. The strength of the drill would be determined by the specifications of your project. You can read about the various drills here: www.dewalt.com You may want to also contact DeWalt directly about this matter to get a more precise answer. Have a great day!

Bosch sells a set of SDS plus bits. Any SDS Plus will fit the hammer. As to whether a 1/2 hole is appropriate really depends on the size of anchor you plan to use. A 1/2" hole for an anchor sounds like a very large anchor.

Make sure that you have the right hardware (four Tapcon 5/16 in. x 2-1/4 in. hex-washer-head large diameter concrete anchors and four 1/4 in. x 5/8 in. galvanized steel flat washers) and tools (hammer driver drill or SDS hammer driver drill is even better and impact driver with the right socket). I use Makita cordless tools. You have to get it right the first time.

I also have the Bosch TI18 18-Piece bit set and seem to go to it more often than the Dewalt bits. I also always back up the exit hole with some scrap wood or tape, which helps to reduce the tear-out.

SteveI've only used my 11240 with a cardide rock drill to drill holes to split rocks with wedges+feathersI have not used it for demolition but using the right bit you shouldn't have a problem breaking up 1 inch concrete as I have drilled 16 in deep holes in granite rocks. Have fun

I believe a hammer drill would be a little more heavy duty for going into concrete. Depending on how hard a job it is, it may suffice, at the risk of burning out the motor?

Not sure. We are a pro concrete cutting and coring company. We use to break out cut concrete. But they do have quite a few attachments that may be used for more delicate operations. I'd google or check with online forums to see what's best if I were you. Right tools for the job is essential. You don't want to go whaling with a fork and spoon. Best of luck.

No, They are designed specifically for SDS Plus type rotary hammer drills, not standard drills/hammer drills. They're built to slide up and down, and are not round where the a regular chuck would clamp them. If you need to drill into concrete, though, an SDS type drill and bits is the best way to go. It's night and day in the difference between using a regular drill with a hammer function and a rotary hammer drill and bit. Rotary hammer drills and bits cut like butter...at least my Bosch does. The bits last far longer and it cuts my labor time tremendously.

Yes, Ridgid is probably the best. Great for close corners. Ridgid double flare tool is super too. Make sure you are using actual "brake copper tubing" not plumbing tubing.
