Serra copo bi-metal Wolfcraft 5469000 40 mm

The Wolfcraft 5469000 is a bi-metal hole saw with a 40 mm diameter, engineered for clean, precise cuts across wood, plastic, plasterboard, non-ferrous metals, and steel sheets. Unlike standard carbon steel hole saws, its bi-metal construction combines HSS teeth with an alloy steel body, delivering high wear resistance and a longer service life. The variable tooth pitch reduces vibration and heat build-up, resulting in smoother cutting and less material tear-out. This single hole saw requires a separate arbor and pilot drill (not included), allowing you to use it with a standard thread connection compatible with common arbors. With a cutting depth of 30 mm, it handles most sheet and board materials in one pass.

Highlights

• Bi-metal construction: HSS teeth on alloy steel body for durability
• 40 mm diameter with variable tooth pitch for smooth, precise cuts
• Suitable for wood, plastic, plasterboard, non-ferrous metals, and steel sheets
• 30 mm cutting depth for efficient drilling in sheet materials
• Standard thread connection for use with separate arbor and pilot drill

In daily use

Ideal for electricians, plumbers, and carpenters, this hole saw excels at creating clean openings for pipes, cables, and fittings. The bi-metal teeth stay sharp longer than carbon steel, reducing the need for frequent replacements. For best results, use a low to medium speed and apply steady pressure. Always pair with a compatible arbor and pilot drill to ensure accurate centering and prevent walking.
