Bosch HSS Bi-Metal Hole Saw

PRIMARY USES

1. Large Diameter Hole Cutting for Installation and Maintenance
Primary Use: A range of HSS bi-metal hole saws (16mm to 46mm diameter) used for cutting large diameter holes in various materials. Essential for electrical installation, plumbing, door hardware installation, and general maintenance work where precise, clean holes are required.
How it helps: For electricians, plumbers, carpenters, and maintenance technicians, the bi-metal hole saws provide fast, clean cutting through metal, wood, plastic, and drywall . The bi-metal construction combines high-speed steel teeth welded to a durable steel body, offering exceptional durability and long-lasting cutting performance . The variable tooth spacing (Vario-Pitch) design ensures low vibrations and high cutting speed, reducing operator fatigue during use . Available sizes from 16mm to 46mm cover the most common diameters for cable entries, pipe penetrations, and hardware installations.
2. Electrical Installation
Primary Use: Cuts holes for cable entries, conduit penetrations, and electrical boxes in distribution boards, cabinets, and walls.
How it helps: The 44mm cutting depth allows drilling through standard wall thicknesses and distribution board panels in one pass . The integrated hexagon adapter and pilot drill bit ensure precise centring and easy start . The bi-metal construction with 8% cobalt alloy provides high heat resistance and reduces the risk of tooth breakage when cutting through electrical panels and metal enclosures .
3. Plumbing Installation
Primary Use: Drills holes for pipe penetrations through walls, floors, and cabinets.
How it helps: The smooth cutting action and low vibration design enable clean, burr-free holes in metal pipes and profiles. The range of diameters from 16mm to 46mm accommodates various pipe sizes commonly used in plumbing installations.

SECONDARY USES

1. Door Hardware Installation: Cuts holes for locks, latches, and door closers.
2. Cabinet Making: Drills holes for cable entries and ventilation in cabinetry.
3. Metalworking: Cuts holes in thin metal sheets, profiles, and enclosures.
4. Plastic and Drywall: Cuts clean holes in plastic pipes, PVC, and plasterboard.
