## Long description

Dedra 08W040 is a 40 mm diameter hole saw designed for creating clean circular openings in a range of materials including metal, stainless steel, aluminium, plastic and wood. Supplied as a single cutter, the hole saw attaches to compatible mandrels and drills to produce precise holes for installation and repair tasks in construction, plumbing, HVAC and workshop environments.
Advantages
The hole saw features a 40 mm cutting diameter that delivers consistent hole sizes for repeatable installations. Its tooth geometry and cutting edge are suited to work with both ferrous and non‑ferrous metals as well as softer materials like plastic and wood, reducing the need to change tools frequently. The single-piece supply ensures straightforward mounting on standard arbors and minimizes setup time on the job.
Suitable for
Drilling circular openings in sheet metal and stainless steel for conduit, pipe or cable passages
Create holes in aluminium panels and profiles for fittings and fastenings
Making openings in plastic and PVC for plumbing and electrical components
Cutting holes in wood for carpentry, fixture installation and workshop projects
Key specifications
Cutting diameter: 40 mm
Compatible with standard drill mandrels and arbors
Material suitability: steel, stainless steel, aluminium, plastic, wood
Form: single-piece hole saw (supplied without arbor)
Typical applications: plumbing, electrical installations, HVAC, general construction and workshop use
How to use
Secure a compatible mandrel or arbor in a power drill, ensuring the shank is tightened according to the mandrel manufacturer’s instructions. Mark the centre of the required hole and, if possible, use a pilot drill to prevent wandering. Fit the hole saw onto the arbor and align the pilot bit (if present) with the marked centre. Start drilling at low speed to establish the cut, then increase speed and apply steady pressure appropriate to the material—lighter pressure for thin metals and plastics, firmer pressure for wood and thicker metal. Periodically withdraw the cutter to clear chips and prevent overheating, and use cutting fluid when working with metals to extend tool life and improve cut quality.
Usage recommendations
Choose a mandrel rated for the drill speed and torque you will use, and select appropriate cutting lubricant when working with steel or stainless steel. Wear eye protection and gloves, clamp the workpiece securely, and allow the tool to cool between extended cuts to maintain safe and accurate operation.
