Learn the real difference between HSS and SDS drill bits. HSS is a high-speed steel material ideal for general-purpose metal and wood drilling, while SDS refers to the shank system used for positioning and rotary core drilling in concrete.

Even with a brand-new granite saw blade, problems show up quickly if somet hing is wrong: chipped edges on countertops, blades turning blue from heat, cuts that wander off line, or a blade that suddenly refuses to bite into the stone. Most of these issues are not random. They follow clear patterns that can be traced back to setup, machine condition, blade choice, and cutting technique.

If you work with granite long enough, the same questions keep coming back: Why is this brand-new granite saw blade chipping my countertop? Why did the last blade burn out halfway through the job? Can I really use the same blade for granite, marble and concrete? Most of these headaches don't come from "bad blades", but from mismatched choices: the wrong blade type for the material, the wrong diameter for the saw, or the wrong bond and RPM for the job.
