Hole saw Dedra 08W019 — diameter 1.9 cm, for metal, stainless steel, aluminium, plastic, wood

Dedra 08W019 is a single-piece hole saw with a 1.9 cm cutting diameter designed for creating precise circular openings in a variety of sheet materials and panels. The tool is suitable for use with standard drill chucks and is intended for plumbing, electrical installation and general DIY tasks where neat, repeatable holes are required in metal, stainless steel, aluminium, plastic and wood.

Advantages

The single-piece construction provides rigidity and reduced runout for cleaner cuts. A 1.9 cm diameter offers a compact size for small-diameter penetrations while remaining compatible with common drills. The tooth geometry and material selection are optimized for cutting through metals and softer substrates without excessive burr formation. Its universal shank fits standard chucks, simplifying setup and replacement during on-site work.

Suitable for

• Cutting holes for pipes and conduits in plumbing and HVAC installations
• Creating cable and conduit entries in electrical cabinets and panels
• Making fixture and fastener access holes in aluminium and metal sheets
• Drilling holes in plastic panels and wooden boards for fittings and passes

Key specifications

• Cutting diameter: 1.9 cm
• Construction: single-piece hole saw
• Compatible materials: metal, stainless steel, aluminium, plastic, wood
• Shank type: fits standard drill chucks
• Intended use: manual and powered drilling for small diameter openings

How to use

Secure the hole saw in the drill chuck and ensure it is tightened to prevent slippage. Mark the centre of the desired hole and, if possible, use a pilot drill or centre punch to reduce wandering on smooth surfaces. Start drilling at low speed to establish the cut, then increase speed as appropriate for the material. Apply steady, moderate pressure and allow the tool to do the cutting; avoid excessive force that can cause overheating or premature dulling. For metal and stainless steel, use cutting fluid or coolant to prolong tool life and improve cut quality. Clear chips periodically to prevent clogging.

Usage recommendations

For the best results, match drill speed and feed to the material: lower speeds for stainless steel, medium speeds for steel and aluminium, and higher speeds for plastic and wood. Use cutting lubricant on metals, clamp thin sheets to prevent deformation, and wear appropriate personal protective equipment such as safety glasses and gloves.
