## Long description

Dedra 08W146 is a single-piece hole saw with a 146 mm cutting diameter designed to create clean round openings in a variety of materials including metal, stainless steel, aluminium, plastic and wood. The tool is intended for professional and DIY use where a large-diameter hole is required; it is compatible with standard mandrels and drills that accept hole saws. The solid construction ensures stable cutting and straightforward mounting on an appropriate arbor.
Advantages
The one-piece design provides increased rigidity and reduces the risk of blade separation during cutting. The tooth geometry and material specification are selected to handle both ferrous and non-ferrous metals as well as softer materials such as plastic and wood. The 146 mm diameter enables large through-holes for conduits, ventilation ducts, pipes and cable routing, while compatibility with common drill chucks and arbors simplifies tool setup.
Suitable for
 Cutting holes for electrical conduits and junction boxes
 Creating openings for plumbing pipes and fittings
 Making ventilation and HVAC access holes
 Cabinetry and joinery requiring large circular holes
 General building and renovation tasks involving mixed materials
Key specifications
 Cutting diameter: 146 mm
 Design: single-piece hole saw
 Material compatibility: metal, stainless steel, aluminium, plastic, wood
 Mounting: suitable for standard hole saw arbors and compatible drill chucks
 Typical applications: through-holes for pipes, conduits, ducts and cable passages
How to use
Secure an appropriate arbor or mandrel to your drill and mount the hole saw firmly according to the arbor manufacturer's instructions. Mark the centre of the hole, clamp the workpiece if possible, and position the pilot or guide to maintain alignment. Use a steady, controlled feed rate and moderate drill speed suitable for the material being cut; apply cutting lubricant when working with metals to reduce heat and improve cutting life. After completing the cut, remove metal shavings or debris and inspect the edge for burrs before finishing.
Usage recommendations
Use appropriate personal protective equipment, including safety glasses and gloves. For metal and stainless steel, use cutting fluid and intermittent drilling to avoid overheating. When cutting wood or plastic, ensure the workpiece is well supported to prevent splintering. Match drill speed and feed pressure to the material to extend tool life and achieve a cleaner cut.
