Bosch Bi-Metal Hole Saw Single 7.6 cm 99.8 g

The Bosch Bi-Metal Hole Saw Single 7.6 cm is a precision cutting accessory designed for creating clean, accurate circular openings in a range of materials. Constructed from bi-metal HSS with cobalt alloy content, this hole saw combines hardness and flexibility to reduce tooth breakage and increase heat resistance during drilling. It is supplied as a single unit with a 7.6 cm cutting diameter and is compatible with standard drill adapters.

Advantages

The bi-metal construction with high-speed steel and cobalt alloy provides improved durability and heat resistance compared with simple carbon-steel saws, while the Vario tooth strip tooth configuration delivers smooth feed and reduced tearing for cleaner hole edges. Its universal fitting makes it compatible with common drill adapters, enabling straightforward mounting and use across a range of drill models. Lightweight design aids handling and reduces operator fatigue during repeated use.

Suitable for

• Cutting circular openings in wood for plumbing, electrical or finishing tasks
• Drilling through thin to medium sheet metal for installations or ventilation
• Creating holes in plastic panels and composite materials for fittings and fixtures

Key specifications

• Cutting diameter: 7.6 cm
• Material: bi-metal high-speed steel with cobalt alloy (HSS-Co)
• Tooth design: Vario tooth strip for smooth cutting
• Weight: approximately 99.8 g
• Compatibility: fits standard hole saw adapters and drill arbors

How to use

Secure the hole saw to a compatible arbor or adapter according to the drill manufacturer’s instructions, ensuring the pilot bit (if fitted) is centered on the intended cutting point. Use a steady, moderate feed rate and appropriate drill speed for the material being cut: lower speeds for metals and higher speeds for wood and plastics. Apply firm, even pressure and withdraw periodically to clear chips and avoid overheating. Use cutting lubricant when working with metals to extend tool life and improve cut quality.

Usage recommendations

For best results, select drill speeds and feed force appropriate to the material: keep speeds low and use lubricant for metals, and higher speeds without lubricant for wood and plastics. Ensure the workpiece is securely clamped and the pilot bit is properly positioned to prevent wandering. Inspect teeth before use and replace the hole saw if teeth are damaged.
