Hole saw Dedra HW4202, 42 mm cutting diameter

Hole saw Dedra HW4202, 42 mm cutting diameter, is a circular cutting tool intended for creating precise round openings with a 42 mm finished size. It is suitable for installation tasks that require clean, consistent holes in materials compatible with its tooth geometry. The tool is compatible with standard drill arbors and can be used with handheld drills or drill presses to produce openings for pipes, fixtures, cable glands and recessed fittings where a 42 mm aperture is required.

Advantages

The Dedra HW4202 hole saw delivers controlled cutting performance and efficient material removal for its nominal diameter. Its geometry is designed to produce relatively smooth hole walls and reduce chipping on appropriate materials. The hole saw is straightforward to install and replace on compatible arbors, enabling rapid changes between sizes during multi-step installations. Designed for common drilling equipment, it offers predictable results when used within recommended application limits.

Suitable for

• Cutting 42 mm round openings in wood and wood-based panels
• Creating holes for pipe entries, cable glands and recessed fittings
• On-site installation work using handheld drills or drill presses
• Electrical and plumbing preparatory drilling where a 42 mm aperture is needed

Key specifications

• Cutting diameter: 42 mm
• Tool type: hole saw (circular cutting blade)
• Compatibility: fits standard drill arbors and compatible drill chucks
• Typical use: through-holes in materials compatible with toothed metal cutting edges

How to use

Secure the hole saw onto a compatible arbor according to the arbor manufacturer’s instructions, then fasten the arbor in the drill chuck. Mark the center point of the intended hole and, if the tool includes a pilot drill, engage it to maintain alignment. Start drilling at a moderate speed and apply steady, even pressure; for larger or harder materials reduce speed and allow the tool to remove material gradually. Clear cut material and chips periodically to avoid clogging and overheating. After cutting, remove the saw from the arbor and deburr the hole edges if necessary.

Usage recommendations

Use appropriate personal protective equipment (eye protection, gloves) and select drill speed and feed rate according to the workpiece material. For clean edges in delicate materials, consider backing the workpiece to minimize breakout. Avoid excessive lateral force and overheating to preserve tooth life and cutting performance.
