Hole Saw Bosch PRO Multi Material PC Plus 44/70 mm — single for drill, drywall, metal, non‑ferrous metal, plastic, softwood

Bosch PRO Multi Material PC Plus 44/70 mm hole saw is a single-piece cutting tool for use with a drill. It is designed to create clean circular openings in drywall, metal, non‑ferrous metals, plastic and softwood, making it suitable for pipe and cable passages, vents and recessed installations. The saw features high-cobalt high-speed steel teeth and is compatible with the Bosch Power Change Plus keyless arbor system for quick fitting and accurate performance.

Advantages

The hole saw uses high-speed steel with 8% cobalt in its teeth to provide longer life and consistent cutting performance across multiple materials. An enhanced tooth geometry enables fast, smooth cuts while the Bosch Power Change Plus compatibility allows quick removal of plugs and rapid swapping of the saw and pilot drill, improving efficiency on the job.

Suitable for

• Cutting circular openings in drywall for recessed lights and junction boxes
• Making holes in thin sheet metal and non‑ferrous metals
• Creating passages in plastic panels and softwood for pipes and cables
• General interior installation work by electricians and plumbers

When it may not be suitable

This hole saw is intended for softer construction materials and thin metal sheets; it is not designed for heavy structural steel or very hard alloys. For demanding industrial metal-cutting tasks or very thick steel plates, a specialized bi-metal or carbide-tipped hole saw designed for those applications would be more appropriate.

Key specifications

• Diameter: 44/70 mm
• Material of teeth: high-speed steel (HSS) with 8% cobalt
• Compatible arbor system: Bosch Power Change Plus (keyless)
• Suitable materials: drywall, metal, non‑ferrous metal, plastic, softwood
• Supplied quantity: 1 piece

How to use

Fit the hole saw to a compatible Bosch Power Change Plus arbor or an appropriate arbor for your drill, ensuring the pilot bit is installed if required. Mark the centre of the desired opening, start drilling at low speed to position the pilot, then increase speed and apply steady, even pressure to cut through the material. Remove the material plug as needed using the Power Change system or by hand when the cut is complete. Follow safety precautions such as wearing eye protection and securing the workpiece.

What to consider before purchase

• Check compatibility of your drill and arbor with Bosch Power Change Plus
• Confirm the 44/70 mm diameter matches the required opening size
• Consider material thickness and type — not intended for very thick or hardened steel

Usage recommendations

Use moderate drill speed and steady pressure for cleaner cuts; keep the pilot bit engaged for guidance and remove metal shavings regularly. For extended tool life, avoid overheating and allow the saw to cool between prolonged cuts.
