Hole Saw Artu 73 mm with Tungsten Carbide Grit Cutting Edge, Model 26417

The Artu hole saw model 26417 with a 73 mm diameter features a tungsten carbide grit cutting edge designed for cutting precise circular openings in hard and abrasive materials. This hole saw is intended for applications where a grit edge provides better cutting performance and durability than tooth-cut hole saws. It is compatible with standard hole-saw arbors and is suited to professional tradespeople and workshop use.

Advantages

The tungsten carbide grit cutting edge provides increased wear resistance on abrasive surfaces, offering longer tool life compared with conventional bi-metal or tooth-type holesaws when working with masonry, ceramic tiles and natural stone. The 73 mm cutting diameter enables clean, consistent holes for pipe sleeves, conduit entries and fixture mounting locations. The design ensures stable cutting with reduced risk of binding in dense materials when used with appropriate drilling speed and feed.

Suitable for

• Drilling openings for pipes and conduits in masonry and concrete
• Cutting holes in ceramic tiles and porcelain during fixture installation
• Creating passthroughs for electrical and plumbing fittings in stone and abrasive substrates
• Workshops and trade jobs requiring precise circular holes in hard materials

Key specifications

• Cutting diameter: 73 mm
• Cutting edge: tungsten carbide grit
• Intended material types: masonry, tile, natural stone and other abrasive substrates
• Compatibility: fits standard hole-saw arbors
• Typical applications: pipe, conduit and fixture openings

How to use

Secure the hole saw onto a compatible arbor and tighten according to the arbor manufacturer's instructions. Mark the centre point of the required hole and, when possible, use a pilot drill or guide to stabilise the saw. Operate the drill at a moderate speed with firm, even pressure—avoid excessive force which can cause overheating or premature wear of the grit edge. For tiled or brittle surfaces, start slowly to prevent cracking. Periodically withdraw the saw to clear debris and allow cooling. Use appropriate personal protective equipment and clamp or support workpieces to prevent movement.

Usage recommendations

Use water or a suitable coolant when cutting in dense stone or ceramic to reduce heat buildup and extend the life of the tungsten carbide grit edge. Match drill speed and feed to the substrate hardness: lower speeds and steady pressure for hard stone and tiles, higher speeds for softer masonry. Inspect the cutting edge before use and replace the hole saw if the grit layer is excessively worn or damaged.
