Hole Saw Bosch PIÅA OTWORNICA PRO Multi Material 89 mm

Bosch PIÅA OTWORNICA PRO Multi Material 89 mm is a precision hole saw designed to cut clean, 89 mm diameter openings in a range of common building materials. Intended for both professional and DIY applications, this multi-material hole saw offers consistent cutting performance for installing pipes, conduits, vents and cable passages. The tool is compatible with standard drill drives and is optimized to produce round, accurate holes with minimal tear-out when used in appropriate substrates such as wood, drywall and similar materials suitable for multi-material cutting.

Advantages

This 89 mm hole saw combines a robust cutting edge with stable body construction to provide repeatable, accurate cuts. The design minimizes material damage around the opening and helps maintain true diameter during use. Its multi-material formulation allows a single tool to address several substrates, reducing the need to change accessories frequently on the job. The saw is suitable for use with hand-held drills and drill presses when proper mounting and feed rates are observed.

Suitable for

• Creating openings for pipes and plumbing installations
• Making vents and duct penetrations
• Routing cables and conduits through walls and panels
• Cutting circular holes in wood and drywall for fixtures and fittings

Key specifications

• Hole diameter: 89 mm
• Material compatibility: multi-material use including wood and drywall
• Cut type: circular hole saw for through-holes
• Intended use: professional and DIY applications requiring precise circular cuts
• Mounting: compatible with standard drill arbor systems (check drill arbor dimensions before use)

How to use

Select a suitable pilot bit or arbor and secure the hole saw to the drill according to the drill and arbor manufacturer’s instructions. Mark the center point of the intended opening and start drilling at low speed to establish the pilot. Apply steady, moderate pressure while cutting; allow the tool to do the work and avoid excessive force that can cause binding or overheating. For deeper cuts or thicker materials, clear debris periodically and reduce feed rate as needed. After cutting, remove the core and deburr the hole if required.

Usage recommendations

Wear appropriate personal protective equipment, including eye protection and gloves. Use proper clamping or support for the workpiece to prevent movement. Match the drill speed and feed rate to the material being cut and allow periodic cooling when cutting dense or abrasive substrates.
