Serra copo bimetal RUKO BSB-HSSCo-16,0-30,5mm com cobalto

Cutting large-diameter holes in tough materials like steel and stainless steel can quickly dull standard hole saws. The RUKO BSB-HSSCo-16,0-30,5mm addresses this with a cobalt-alloyed high-speed steel cutting edge that retains hardness at high temperatures, paired with a special alloy steel body for durability.

Who is it for

Professional tradespeople and serious DIYers who need to cut precise 16 mm holes in metal, wood, plastics, and other materials. Ideal for electricians, plumbers, and metal fabricators.
