Hole saw Dedra 08W070, diameter 70 mm, for metal/stainless steel/aluminium/plastic/wood

Dedra 08W070 is a single-piece hole saw with a 70 mm cutting diameter designed to produce clean circular openings in a variety of materials including metal, stainless steel, aluminium, plastic and wood. The tool mounts to compatible drills or arbor adapters and is intended for creating holes for pipework, cable entries, ventilation, and mounting hardware during installation and repair tasks.

Advantages

The single-piece construction provides dimensional stability and reduces the risk of misalignment during cutting. Its 70 mm diameter offers a standard size for many plumbing, electrical and ventilation applications. The saw's cutting profile and tooth geometry are suited to a range of materials, making it a versatile choice for both DIY users and professionals. Compatibility with common drill arbors allows quick attachment and straightforward use on-site.

Suitable for

• Cutting circular openings in thin metal sheets and stainless steel panels
• Creating holes in aluminium components and plastic housings
• Drilling through timber and composite wood for fittings and fixtures
• Making entry points for cables, conduits and small-diameter pipes
• On-site installations and maintenance tasks requiring precise circular holes

Key specifications

• Cutting diameter: 70 mm
• Construction: single-piece hole saw
• Material compatibility: metal, stainless steel, aluminium, plastic, wood
• Attachment method: fits standard drill arbors or compatible adapters
• Typical applications: pipework openings, cable entries, vents, mounting holes

How to use

Secure the hole saw to a compatible drill arbor or adapter according to the drill and arbor manufacturer instructions. Mark the centre point of the intended hole on the workpiece. If possible, clamp the workpiece to prevent movement. Start drilling at low speed to establish the pilot position, then increase speed and apply steady, even pressure, allowing the saw teeth to cut without excessive force. For metal and stainless steel, use cutting fluid to reduce heat and prolong tool life. Retract periodically to clear chips and prevent clogging. After completing the cut, remove any burrs from the hole edge with a file or deburring tool.

Usage recommendations

Use appropriate personal protective equipment including safety glasses and gloves. Match drill speed and feed to the material: lower speeds for stainless steel and harder metals, moderate speeds for aluminium and plastics, and higher speeds for wood. For extended cutting in metal, apply cutting lubricant and allow the saw to cool between cuts to maintain cutting performance and extend service life.
