Bosch says its Speed-X hammer carbide performs better the deeper it drills, owing to its shortened head design and enlarged dust-clearing channels. Holes start precisely, thanks to the centric carbide tip, and begin quickly as the inclined side cutters power their way into concrete. Vacuum-optimized brazing and heat treatment of the precision carbide tip provides resistance to impact and thermal stresses, and contributes to an 18% increase in lifetime. The same shortened head and inclined cutting slots also enhance durability by providing fast dust removal and reducing friction. Speed-X alerts users when the carbide tip is worn and will no longer deliver precision anchoring at the start of drilling. Speed-X will be available in SDS Max and Spline through authorized dealers.
