Hole saw Dedra 08W111 — diameter 111 mm for metal, stainless steel, aluminium, plastic, wood

Dedra 08W111 is a single-piece hole saw with a cutting diameter of 111 mm designed for drilling round openings in metal, stainless steel, aluminium, plastic and wood. Manufactured for use with compatible arbors and standard drills, this hole saw provides a straight-cutting geometry intended for through-holes and panel work in construction and installation tasks. The tool is suitable for applications that require a clear circular aperture and is designed for use on a variety of sheet and panel materials.

Advantages

The single-piece construction reduces the risk of misalignment and simplifies mounting on an arbor. Hardened cutting teeth and a stable body deliver consistent cutting performance across different materials, while the medium-large 111 mm diameter covers common installation needs for pipe and conduit penetrations. The design allows efficient chip removal and reduces finishing work after cutting, making it practical for trade professionals and maintenance work.

Suitable for

• Drilling circular openings in steel and stainless steel sheets
• Creating holes in aluminium panels and profiles
• Cutting apertures in plastic housings and PVC panels
• Making through-holes in wooden boards and plywood
• HVAC, electrical, plumbing and general construction installations

Key specifications

• Cutting diameter: 111 mm
• Construction: single-piece hole saw
• Intended materials: metal, stainless steel, aluminium, plastic, wood
• Mounting: for use with compatible drill arbor and standard power drills
• Application type: through-holes and panel cutting

How to use

Attach the hole saw to a compatible arbor and secure it into a drill according to the arbor and drill manufacturer’s instructions. Mark the centre point of the required opening and, if needed, pilot-drill a small guide hole to stabilise the arbor. Operate the drill at a suitable speed for the material being cut, applying steady pressure and allowing the tool to cut without forcing. Clear chips periodically to maintain cutting efficiency and check the cut for alignment. After completing the hole, deburr the edges if necessary.

Usage recommendations

Use appropriate personal protective equipment including eye protection and gloves. Select drill speeds and feed rates matched to the workpiece material: lower speeds for stainless steel, medium speeds for aluminium and higher speeds for plastics and wood. When cutting metal, use cutting fluid to extend blade life and improve finish. Ensure the arbor and drill are rated for the hole saw diameter and follow safety guidelines for power tool use.
