Hole saw Bosch Bi‑Metal Single for drill, Ø 2 cm, suitable for drywall/metal/plastic/wood, 1 pc, box

Single Bosch Bi‑Metal hole saw for drill, diameter 2 cm, designed to cut drywall, metal, plastic and wood. The bi‑metal construction combines high‑speed steel with an alloy containing cobalt for increased wear resistance while maintaining cutting performance. Supplied as one piece in a box, this hole saw is intended for creating through holes for mounting, electrical and plumbing openings and other general installation tasks.

Advantages

The Vario tooth strip is configured to glide through a range of materials and produce smooth, controlled cuts. Bi‑metal HSS with cobalt content increases edge life and resists heat build‑up during use, reducing the need for frequent tool changes. The standard threaded fitment ensures compatibility with common drill adapters, allowing quick replacement and secure attachment to a drill.

Suitable for

• Cutting holes in drywall for sockets, fixtures and cable passages
• Drilling openings in thin to medium sheet metal for installations
• Creating apertures in plastic panels and conduits
• Making precise through holes in soft and medium woods for mounting hardware

Key specifications

• Diameter: 20 mm (2 cm)
• Construction: bi‑metal with HSS containing cobalt
• Tooth design: Vario tooth strip for smooth cutting
• Compatibility: threaded standard adapter (for use with common drill arbors)
• Quantity: 1 piece per box

How to use

Install the hole saw onto a compatible threaded adapter and secure it to a drill with appropriate speed and torque settings for the material. Mark the centre point of the hole and start drilling at low speed to establish the cut, then apply steady pressure while increasing speed as appropriate for the material. Withdraw periodically to clear chips and avoid overheating. After completing the cut, remove burrs as needed for a clean finish.

Usage recommendations

Use cutting oil or coolant when working with metal to extend tool life and reduce heat. For plastics, use lower speeds to prevent melting; for drywall and wood, moderate speeds and stable feed pressure will yield cleaner edges. Always wear appropriate personal protective equipment and secure the workpiece before drilling.
