Hole saw Dedra 08W022, diameter 22 mm, for metal, stainless steel, aluminium, plastic, wood

Dedra 08W022 is a single-piece hole saw with a 22 mm cutting diameter designed to create precise round openings in a variety of materials. Constructed for compatibility with standard drills and drill drivers, this hole saw is intended for cutting through metal, stainless steel, aluminium, plastic and wood. Its compact diameter and single-piece design provide straightforward mounting and stable cutting for installation, plumbing, electrical and general workshop tasks.

Advantages

The one-piece construction reduces wobble and improves concentricity while cutting, helping to produce clean, accurate holes. A 22 mm cutting diameter fits common installation needs for fasteners, conduit and pipe pass-throughs. Compatibility with a range of materials — metal, stainless steel, aluminium, plastic and wood — makes the tool versatile across trades. The saw is suitable for use with standard drills and drill drivers, enabling quick changes between drilling tasks in the workshop or on-site.

How to use

Mount the hole saw securely in a compatible drill or drill driver following the drill manufacturer's instructions for arbor and chuck tightening. Mark the centre point of the required hole and, if needed, use a pilot drill to create a starter guide. Operate the drill at a steady speed appropriate for the material being cut; reduce speed and apply firm, even pressure when cutting thicker or harder metals. Clear chips regularly to maintain cutting efficiency and avoid overheating. After cutting, deburr the hole edges as required for the specific installation.

Usage recommendations

Use cutting fluid or lubricant when working with stainless steel or other hard metals to reduce heat and prolong tool life. For plastic and wood, select lower speeds to avoid melting or splintering. Ensure the drill and arbor are rated for the material and follow appropriate safety measures, including eye protection and securing the workpiece.
