MULTI-PURPOSE DRILL BIT FOR ROTARY OR PERCUSSION DRILLING
Cobalt and tungsten carbide tip. Chrome vanadium steel shank for enormous strength. These multi-purpose drill bits represent a revolutionary new hole drilling system. Using high-quality German design and high-tech manufacturing, we have created drill bits that are 3-4 times stronger than the typical single-purpose bit. To achieve this incredible strength and versatility, the tip is bonded to the shaft in a vacuum, at extremely high temperatures. This special brazing technique allows the bit to withstand drilling temperatures up to 2000 degrees Fahrenheit, without damage to the tip or the shaft. These multi-purpose drill bits are the perfect single hole drilling tools for any job and any user, from contractors to homeowners, craftsmen, maintenance workers and others. They are highly effective on a multitude of surfaces, including masonry, ceramic tile, concrete, brick, fiberglass, plexiglass, glass, cast metal, hardened steel, granite, marble and wood.
