Hole saw KWB 499190 90 mm — circular cutter for wood and soft materials

Hole saw KWB 499190 90 mm is a circular cutter designed to create large, precise round openings in wood and other soft materials. The tool fits standard arbors and delivers clean cuts for installing pipes, cables, vents and fixtures. Its 90 mm diameter provides a common size for many building and renovation tasks, while a design focused on efficient material removal helps maintain drilling speed and reduce binding.

Advantages

The hole saw offers accurate, consistent circular cuts with minimal splintering when used with appropriate pilot bits and backing. Its tooth geometry and rim design are optimised for cutting wood and similar soft substrates, ensuring efficient chip evacuation and reduced heat buildup. Compatibility with standard drill arbors simplifies replacement and setup, making it suitable for both workshop and on-site use.

Suitable for

• Cutting round openings for pipes and conduits in wooden panels
• Creating holes for ventilation outlets and ductwork in soft materials
• Drilling access holes for cables and electrical fixtures
• Carpentry and renovation tasks requiring 90 mm diameter holes

Key specifications

• Nominal diameter: 90 mm
• Cut type: circular hole saw for wood and soft materials
• Material compatibility: solid wood, plywood, chipboard, MDF and similar soft substrates
• Mounting: fits standard drill arbors and mandrels
• Cutting action: tooth rim designed for efficient material removal

How to use

Secure the appropriate arbor and pilot bit to ensure centered drilling. Mark the hole position on the workpiece and, where possible, clamp the material to prevent movement. Start drilling at low speed to establish the pilot hole, then increase speed within the drill manufacturer’s recommended range while applying steady, moderate pressure. Periodically withdraw the saw to clear chips and reduce heat. For cleaner exit holes, support the underside of the workpiece or use sacrificial backing material.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Select a suitable pilot bit and arbor compatible with your drill. Avoid excessive feed pressure and prolonged continuous cutting in a single pass to prevent overheating; allow the tool to cool if it becomes hot. When working with veneered or splinter-prone surfaces, use backing to minimise tear-out.
