Hole Saw Bosch Bi‑Metal Single for Drill, Ø 2.1 cm, for Drywall Metal Plastic Softwood, 1 pc

Single Bosch Bi‑Metal hole saw for drill, Ø 2.1 cm, designed for precise circular holes in drywall, metal, non‑ferrous metal, plastic and softwood. The cutter is manufactured from bi‑metal high speed steel with cobalt content, providing durability and consistent performance for through holes and panel work. Supplied as one piece and compatible with standard adapters, this hole saw is intended for renovation, electrical, plumbing and carpentry applications where a clean, controlled cut is required.

Advantages

The bi‑metal construction with cobalt‑enriched high speed steel improves wear resistance and retains cutting performance during repeated use. A Vario tooth strip tooth configuration promotes smooth gliding through materials and reduces tearing, enabling accurate circular cuts. The tool’s dimensions and 44 mm cutting depth capacity make it suitable for typical installation thicknesses while maintaining compatibility with common drill adapters for quick setup.

Suitable for

• Cutting circular openings in drywall for sockets and boxes
• Making through holes in thin sheet metal and non‑ferrous metals
• Drilling holes in plastic panels and conduit
• Create openings in softwood for carpentry fittings and pipe routing

How to use

Mount the hole saw onto a compatible adapter or arbor and secure it to a drill with appropriate speed control. Mark the center of the intended hole, start drilling at low speed to establish the pilot position, then increase speed and apply steady, even pressure. Cool the tool or reduce speed when cutting metal to avoid overheating. After completing the cut, remove the plug and deburr the hole as needed for a clean finish.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves) and select drill speeds suited to the material: lower speeds for metal, medium to high speeds for drywall and plastic. Ensure the workpiece is clamped securely and clear chips regularly to maintain cutting efficiency and prolong tool life.
