Hole saw Dedra HW4255, 55 mm cutting diameter

Hole saw Dedra HW4255, 55 mm cutting diameter is a compact circular cutting tool designed for making precise round openings in a range of common materials. It is intended for use with compatible drills and arbors and can be fitted where standard bi-metal or high-speed hole saws are suitable. Typical applications include creating holes for plumbing fixtures, electrical boxes, ventilation ducts and other installations that require a neat circular aperture.

Advantages

The 55 mm cutting diameter provides a standardized size for many installation tasks while the compact design supports controlled cutting and reduced wobble when used with a suitable arbor and pilot bit. Constructed for compatibility with standard hole saw systems, this model allows quick replacement and interchange with commonly available mandrels. The tool delivers clean circular cuts in materials appropriate for bi-metal or high-speed hole saws when used with recommended speeds and feed rates.

Suitable for

• Cutting holes for plumbing pipes and fittings
• Creating openings for electrical boxes and conduit
• Installing small ventilation ducts or air vents
• Fabrication tasks in wood, plastics and light metals (when using the correct hole saw type and arbor)

Key specifications

• Cutting diameter: 55 mm
• Intended use: circular hole cutting with drill and arbor
• Compatibility: standard hole saw systems (bi-metal or high-speed types as appropriate)
• Typical materials: wood, plastics, light metals (dependent on chosen saw type)
• Form factor: compact round cup design for precise cuts

How to use

Fit the hole saw to a compatible arbor and secure the pilot bit. Clamp the workpiece as needed to prevent movement. Select a drill with adequate power and set a suitable rotational speed for the material and saw type. Start drilling at a steady, controlled feed and allow the saw teeth to cut without applying excessive lateral force. Withdraw periodically to clear chips and reduce heat buildup, especially when cutting metals or dense materials. After completing the cut, remove the cup and clean or deburr the hole as required.

Usage recommendations

Use the hole saw with the correct arbor and pilot bit for stable operation. Match the specific hole saw type to the material: bi-metal for general-purpose cutting including thin metals and wood, high-speed for harder materials if appropriate. Employ appropriate drill speed, cooling or lubrication for metal cutting, and wear eye and hand protection during operation.
