Electricians, plumbers and carpenters reach for this Bosch Expert hole saw set when they need clean, accurate holes in wood, metal, plastic and plasterboard. The set includes 11 bi-metal hole saws in the most common trade diameters from 19 mm to 76 mm, plus two arbors with integrated pilot drills and a hex key, all stored in a robust case.

Key specifications

• Hole saw diameters: 19, 22, 25, 29, 35, 38, 44, 51, 57, 64, 76 mm
• Cutting depth: 40 mm
• Material: Bi-metal with variable tooth pitch
• Shank type: Hexagonal
• Number of pieces: 14 (11 hole saws, 2 arbors, 1 hex key)
• Storage case included

Why choose it

The bi-metal construction combines a tough, wear-resistant high-speed steel tooth strip with a flexible alloy steel body, so the hole saws cut fast and last long. The variable tooth pitch reduces vibration and chatter, giving you rounder holes and a smoother finish. The arbors fit both corded and cordless drills with a standard three-jaw chuck.

Ideal use cases

• Drilling through wooden studs, plywood and chipboard
• Cutting holes in sheet metal, aluminium and non-ferrous metals
• Making openings in plasterboard and plastic panels
• Installing pipework, cable conduits and downlights

Good to know

The set includes two arbors, so you can keep one fitted to a small hole saw and one to a large hole saw for quick changes. The hex key is used to tighten the hole saw onto the arbor. The storage case keeps the hole saws organised and protected.
