Hole saw Dedra 08W029, diameter 29 mm, for metal, stainless steel, aluminium, plastic, wood

Dedicated hole saw Dedra 08W029 with a 29 mm cutting diameter is designed to cut clean circular openings in a variety of materials including metal, stainless steel, aluminium, plastic and wood. Supplied as a single piece, this hole saw fits standard drill arbors and is intended for use in construction, metalworking and general DIY tasks where precise round holes are required for pipes, conduits, fasteners or cable passages.

Advantages

The tool offers a 29 mm cutting diameter that provides consistent, repeatable hole size for installation tasks. Its tooth geometry and cutting edge are suitable for use across multiple materials, allowing the same tool to be used on metal, stainless steel, aluminium, plastic and wood without frequent tool changes. Compatibility with standard drill arbors ensures quick attachment and removal while maintaining stability during drilling. The single-piece design reduces the number of components to handle on site.

How to use

Mark the centre of the hole on the workpiece and secure the material to prevent movement. Fit the hole saw onto a compatible drill arbor and tighten according to the arbor instructions. Start drilling at low speed to establish the pilot, then increase speed and apply steady, moderate pressure while allowing the cutter to remove material. For metal and stainless steel, use appropriate cutting fluid and reduced feed to prolong tool life and improve chip evacuation. After cutting, remove any burrs from the edge before installing pipes or fittings.

Usage recommendations

Use appropriate personal protective equipment including safety glasses and gloves. For best performance on hard materials, ensure the drill is held perpendicular to the work surface and avoid excessive pressure or high speeds that can cause overheating. When cutting metal or stainless steel, apply cutting fluid and periodically withdraw the saw to clear chips.
