Hole saw Dedra 08W114, 114 mm diameter, for metal, stainless steel, aluminium, plastic, wood

Dedra 08W114 is a 114 mm diameter hole saw designed to create clean circular openings in a variety of materials including metal, stainless steel, aluminium, plastic and wood. Supplied as a single unit, the tool is compatible with standard arbors and drill drivers to produce consistent, accurate holes for installations such as pipework, ventilation ducts and electrical fittings. The circular cutting edge and robust body provide controlled cutting performance suitable for both workshop and on-site tasks.

Advantages

The hole saw delivers a large 114 mm cutting diameter that simplifies the creation of standardized openings. Its cutting geometry and material compatibility allow use across mixed-material jobs without swapping tools frequently. The single-piece supply reduces setup complexity and the design supports attachment to common arbors and drill drivers for straightforward operation. Overall, the tool offers reproducible hole quality with a focus on practicality and cross-material performance.

Suitable for

• Drilling circular openings for pipes and conduits in metal and plastic surfaces
• Creating ventilation and HVAC duct inlets in sheet metal or wood panels
• Installing electrical fixtures or recessed fittings in walls and panels
• General workshop hole cutting where a 114 mm diameter is required

Key specifications

• Cutting diameter: 114 mm
• Material compatibility: metal, stainless steel, aluminium, plastic, wood
• Supply format: single-piece hole saw
• Mounting: compatible with standard arbors and drill drivers

How to use

Select a compatible arbor and secure the hole saw to the drill driver according to the arbor manufacturer's instructions. Mark the center point of the required opening and start drilling at a low speed to create a pilot impression, then increase speed and apply steady pressure while keeping the drill perpendicular to the workpiece. For metal and stainless steel, use cutting fluid and moderate feed to reduce heat and prolong cutting edge life. Clear swarf periodically to avoid jamming and complete the cut by slowing down as the blade exits the material to maintain a clean edge.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and gloves. For durable metals and stainless steel, employ coolant or cutting oil and moderate feed rates; for plastics and wood, reduce speed to prevent melting or splintering. Ensure the arbor is rated for the saw diameter and maintain secure clamping of the workpiece for accurate, safe cutting.
