Hole Saw Artu 43mm with Tungsten Carbide Grit Cutting Edge, model 26414

The Artu hole saw with a 43 mm cutting diameter and a tungsten carbide grit cutting edge is a purpose-built tool for cutting precise round holes in a range of common building materials. The carbide grit coating on the cutting rim increases wear resistance and maintains cutting performance when working with abrasive surfaces. Designed for use with compatible drill/arbor assemblies, this hole saw is intended for trades and DIY tasks that require accurate, long-lasting hole cutting.

Advantages

The tungsten carbide grit cutting edge provides enhanced durability and prolonged life compared with standard bi-metal hole saws, reducing the frequency of replacement. Its 43 mm diameter delivers consistent, accurate hole sizes for fittings and fixtures. The reinforced cutting rim tolerates contact with harder and more abrasive materials, maintaining cutting speed and reducing chipping around the hole perimeter. The tool’s design is compatible with common drill arbors and drill drivers, enabling straightforward attachment and stable operation.

Suitable for

• Cutting round holes for plumbing fixtures and pipe penetrations
• Installing electrical boxes, conduits and cable entries
• Carpentry tasks requiring precise circular cutouts in boards and panels
• Working with abrasive or harder sheet materials where increased edge wear may occur

Key specifications

• Cutting diameter: 43 mm
• Cutting edge: tungsten carbide grit coated rim for wear resistance
• Intended mounting: use with compatible drill arbor or mandrel
• Primary application materials: wood, composite boards, some abrasive sheet materials and non-hardened substrates

How to use

Secure the hole saw to a compatible arbor or mandrel according to the arbor manufacturer’s instructions and tighten the fixing securely. Mark the center point of the required hole and, if possible, use a pilot drill or guide bit to establish starting position and prevent walking. Operate the drill at a controlled speed suitable for the material being cut; lower speeds are typically recommended when cutting abrasive materials to extend cutting edge life. Apply steady, even pressure and avoid excessive force that could overload the drill or damage the saw. Clear debris periodically to maintain cutting efficiency.

Usage recommendations

For best results, use suitable personal protective equipment such as safety glasses and gloves, and, where applicable, dust extraction or a vacuum to remove particles. Inspect the cutting edge before use and replace the hole saw when the carbide grit shows significant wear or the cutting performance declines.
