Yes, if the chuck opens wide enough. It might bugger up the SDS end for future use though.

how do i keep an outside door from swelling?

Asked by HOSS March 25, 2015

Answers

We first have to look at the material or type of wood that was used to build the door. If the door is well installed and we give it the treatment it needs and then we paint it, it should not inflate. tip if the door is already inlaid we remove it we fix the door frame well. Then we start working with the door where it is colliding we can pass an electric brush as soon as it is fixed we pass it sandy sealer then the desired tint and then the varnish or paint.

yes, we can pass aluminum and metal at low speed. I am an electrician for more than 30 years I have passed the electrical panel boxes either aluminum or metal and then I pass the cement without fear of the bit being damaged.

Answers

This bit requires a SDS Plus rotary hammer, which will eat through concrete like butter. A regular hammer drill won’t accept this type of bit. If you have a regular hammer drill you must use the tungsten carbide. A hammer drill will take much longer to drill the hole.

Bulldog really only large enough for smaller holes in concrete, brick, sandstone, etc. Not very efficient drilling in igneous rock or aggregate product. U need to upgrade your drill to bosch max with a spline shaft drill bit. U can rent them if necessary, cost btwn $380 to $420 and bits are $50, should use a 4 point carbide tip for better cutting.

Thank you for your question. The SDS-Plus bits will work with any of our SDS Plus rotary hammer or the old style SDS hammers. They will not work with the large SDS-Max hammers. All of the Bulldog models will accept SDS-Plus.

A nice masonry bit that worked well for me. BACKGROUND: I use TAPCON screws when I work masonry projects. With an SDS hammer drill a good bit can make a clean hole quickly. I have Bosch bits, but this was my first SDS bit. FIT AND FINISH: Clean and functional in appearance the Bulldog bit looks like it’s ready to go. OPERATION: I installed the bit in my DeWalt hammer drill and drilled a few test holes. One in firebrick and two in a concrete anchor block. The bit broke the firebrick, but that was my fault as it was a small piece and unsupported. In the concrete anchor the bit drilled a 1 ½” deep hole with no problems. The bit removed the debris from the hole well and the hole itself was clean with minimal chip-out at the entrance. I use the bit to install a handrail to my side stairs for 6 TAPCON screws. It drilled into both the mortar and the brick with minimal problem and the screws drove in perfectly. SUMMARY: A good bit that met my need perfectly. A welcome addition to my TAPCON toolbox.

(What's this)
This SDS bit is a good example of newer bit tip technology. First SDS is a mounting system for rotary hammer drill systems, for cement , stone type surfaces. SDS mount is a spring loaded type chuck which allows for a simple insertion into the drill chuck . There is no need for having to tighten the chuck to the bit. You will se this type of mount on most rotor hammers , chisel type drills. The Bosch bit here is a SDS mount Bulldog Xtream SDS plus , the biggest thing I can see is the tip has an extra cuting edge perpendicular to the stone cutting edge. The claim is for it to be able to drill Soft steel embedded in concrete. The Plus is industry wording for heavy duty. Off to the races I tried a basic hole for a fastener in sander block worked effortlessly in hammer mode, no better then other brands in my box. I tried to also drill a hole out of hammer mode , because of its size not an issue. I did like this as with other bits I've had a hard time starting the hole. Very useful if your drilling Soft natural stone that could crack , with out the hammer the it didn't crack. I tried going thru rebar with mixed results in the hammer mode the bit really went around the rebar not leaving a bent bit but not cutting the bar either . I also tried once I hit the rebar switching to regular drill mode and it did cut through the metal , not great but did work. Of course I knew where the rebar was which most cases in the field you don't . The bit was still usable after this too. Not sure this bit is any better then other high end name brands but work equally as good. Is the Plus any better then regular SDS maybe in the hardness of the bit material and how much your doing with the bit. Most smaller diameters for light work load probably the plus is overkill but I guess if you want a bit in you arsenal that will be there for you in duration it's a good idea .

German engineering at its best! This drill bit is probably the best you can buy. It is claimed to have 4x the life of regular bits. It is designed for drilling through concrete even if there is a chance of hitting rebar. The SDS plus fitting fastened firmly into my Milwaukee SDS hammer drill and came out easily when I was finished too. The tip has what looks like some special shape to aid drilling. It removed easily from the packaging. Rated for 1300 RPM maximum speed. Made in Germany!

This bit worked great in concrete, but not so good when it hit rebar. Had to change bits for rebar, and change back this to finish the job.

I've cut about 50 holes so far in granite blocks and curbing, as well as in "fieldstone" for splitting. The drill show no sign of slowing down. I don't use any pressure at all. I just let the hammer drill action and the bit do all the work. Effortless! I just bought a 10" version because I liked this so much and needed something longer for stones, which don't cleave as nicely as granite block. I could not be happier with this bit.
