Hole Saw Dedra 08W038 — 38 mm Diameter, for Metal, Stainless Steel, Aluminium, Plastic, Wood

Dedra 08W038 is a 38 mm diameter hole saw designed for creating circular openings in a range of materials including metal, stainless steel, aluminium, plastic and wood. Supplied as a single cutting piece, the tool is intended for use with a suitable pilot drill and arbor. It is suitable for tasks that require accurate round holes such as pipe entries, electrical boxes, ventilation ducts and fittings.

Advantages

The hole saw features a 38 mm cutting diameter that provides a standardized size for many installation and repair tasks. Its construction is suitable for cutting both ferrous and non-ferrous metals, as well as softer materials like plastic and wood, reducing the need to change tools between jobs. Delivered as an individual unit, it is easy to store and replace on compatible arbors. When paired with the correct pilot drill and appropriate cutting speeds, the tool gives clean, consistent holes and reduced heat buildup.

Suitable for

• Creating cable and pipe openings in walls, panels and enclosures
• Cutting holes for electrical boxes, switches and sockets
• Making ventilation and duct penetrations
• Installing plumbing fittings and conduits

Key specifications

• Cutting diameter: 38 mm
• Compatible materials: carbon steel, stainless steel, aluminium, plastic, wood
• Delivery format: single hole saw piece (requires arbor and pilot drill)
• Typical applications: through-hole cutting for installations and fittings

How to use

Fit the hole saw onto a compatible arbor and secure a suitable pilot drill. Mark the center of the required opening, position the pilot drill, and start drilling at low speed to establish the guide. Increase speed gradually according to the material being cut, applying steady pressure without forcing the tool. For metals and stainless steel use slower speeds and cooling lubricant as needed; for aluminium, plastics and wood higher speeds are acceptable but monitor heat to avoid melting or burning. After cutting, remove any burrs and inspect the hole for fit.

Usage recommendations

Use the appropriate arbor and pilot bit, select cutting speed and lubrication based on the material, and wear eye and hand protection during operation. Replace the hole saw if teeth are worn or damaged to maintain cutting quality and reduce risk of binding.
