Hole saw Bosch PRO Multi Material PC Plus 44/48 mm — single piece for drills

Hole saw Bosch PRO Multi Material PC Plus 44/48 mm — single piece for drills is a single-piece bi-metal hole saw designed for creating circular openings in a range of building and installation tasks. With a nominal diameter of 44/48 mm, it is intended for cutting into drywall, metal, non-ferrous metals, plastic and softwood. The tool is compatible with drills and designed to be used with Bosch Power Change Plus keyless arbors for quick mounting and plug removal, making it suitable for electricians, plumbers and general tradespeople who need a versatile cutter for installation work.

Advantages

The hole saw features high-speed steel teeth with approximately 8% cobalt content for increased wear resistance and longer life when cutting varied materials. An enhanced tooth geometry ensures efficient, fast and smooth cutting action across drywall, thin metal sheets and soft wood. The Power Change compatibility simplifies changing the hole saw and extracting cut plugs, reducing downtime during repetitive installation tasks. The single-piece design improves stability during cutting and reduces the risk of misalignment.

Suitable for

• Cutting circular openings for electrical boxes and conduit in drywall and plasterboard
• Creating holes for plumbing pipes and fittings in light wood and plastic
• Making pass-throughs for ventilation fixtures and cable entry in thin metal and non-ferrous sheets
• On-site retrofit and renovation work where multiple materials are encountered

Key specifications

• Diameter: 44/48 mm (nominal)
• Material of cutting edge: high-speed steel with approx. 8% cobalt
• Design: single-piece bi-metal construction for stability
• Compatible mounting system: Bosch Power Change Plus keyless arbor compatibility
• Intended materials: drywall, metal, non-ferrous metals, plastic, softwood

How to use

Fit the hole saw onto a compatible arbor or Bosch Power Change Plus keyless system following the drill and arbor manufacturer instructions. Mark the center of the required opening, secure the workpiece where possible and use a pilot bit or guide to start the cut accurately. Operate the drill at a suitable speed for the material being cut—lower speeds for metals and higher speeds for drywall and softwood—apply steady, even pressure and allow the saw teeth to remove material without forcing. After completing the cut, stop the drill and remove the plug using the Power Change system or by careful extraction according to safety guidance.

Recommendations

Use appropriate personal protective equipment including eye protection and gloves. When cutting metal, secure the workpiece and use cutting lubricant or reduced speed to prolong tool life. Avoid excessive side pressure to maintain tooth life and accuracy. Inspect the hole saw regularly and replace when tooth wear affects cutting performance.
