Questions & Answers
can this bit work on a regular drill - non-hammer drill?
Asked by TheKid July 5, 2018Yes, if the chuck opens wide enough. It might bugger up the SDS end for future use though.
does this bit fit the HILTI hammer drill?
Asked by james April 9, 2014yes
how do i keep an outside door from swelling?
Asked by HOSS March 25, 2015We 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.

Asked by Will February 24, 2020This 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.
