Serra copo RUKO LOS-HSSCo-30 mm, 30 mm de diâmetro, HSS-Co bimetal, 38 mm de profundidade de corte

For electricians and plumbers who need clean, large-diameter holes in wood, metal, or plastic, the RUKO LOS-HSSCo-30mm hole saw delivers fast cutting and long tool life. Its bi-metal construction combines a flexible alloy steel body with high-speed steel teeth containing cobalt for excellent heat resistance.

Key specifications

• Diameter: 30 mm
• Cutting edge material: HSS-Co (high-speed steel with cobalt)
• Body material: Bi-metal (alloy steel)
• Cutting depth: 38 mm
• Tooth pitch: Vari-pitch
• Arbor thread size: 1/2"-20 UNF
• Recommended materials: Wood, metal, plastic, plasterboard, non-ferrous metals

Why choose it

The aggressive vari-pitch tooth geometry reduces vibration and increases cutting speed, while the cobalt-enriched teeth withstand high temperatures for extended use. The shatter-resistant bi-metal design provides flexibility without sacrificing strength.

Ideal use cases

• Drilling holes for pipes and conduits in wood and plasterboard
• Creating openings in metal enclosures and panels
• Cutting non-ferrous metals such as aluminium and copper

Good to know

This hole saw requires a separate arbor (e.g., Lenox 2L or 5L) for mounting. It is a single hole saw, not a set.
