Sierra de corona bimetálica HSS-Co RUKO LOS-HSSCo-27 mm

The RUKO LOS-HSSCo-27mm hole saw stands out with its cobalt-alloyed HSS cutting edge, engineered for clean cuts in stainless steel and other tough metals where standard bi-metal saws struggle. The variable pitch tooth design reduces vibration and delivers smooth results across a broad range of materials.

Highlights

• 27 mm cutting diameter with 38 mm cutting depth
• HSS-Co bi-metal construction for high heat resistance and durability
• Variable pitch teeth for reduced vibration and smoother cutting
• 5/8"-18 UNF arbor thread fits standard hole saw arbors
• Suitable for stainless steel, steel, non-ferrous metals, wood, plastics, plasterboard, and drywall

In daily use

This hole saw is built for professional and industrial applications where precision and longevity matter. The cobalt-alloyed cutting edge maintains sharpness longer than conventional HSS, even when cutting abrasive materials. The bi-metal body absorbs shock and resists deformation, ensuring consistent hole quality over repeated use.
