Hole Saw Arbor Irwin 10504535 for hole saws 32–152 mm, 13 mm shank

Arbor Irwin 10504535 is an adapter designed to mount and drive hole saws with diameters from 32 mm to 152 mm using a 13 mm shank. The arbor accepts bi-metal and carbide hole saws and provides a pilot drill attachment point and secure locking for concentric, stable cutting. It is intended for use with hand-held and machine drills on materials such as metal, wood and plastic, offering a practical solution when changing between hole saw sizes and workpieces.

Advantages

The arbor features a standard 13 mm shank for compatibility with most drill chucks and a locking mechanism that secures the hole saw to reduce wobble and improve concentricity. Its design accommodates a wide range of hole saw diameters from 32 mm to 152 mm, eliminating the need for multiple dedicated arbors. The built-in pilot drill attachment point improves guidance during starting and helps maintain accuracy when drilling through different materials.

Suitable for

• Cutting circular holes in metal sheet, steel and thin metal profiles
• Drilling holes in timber for installation of pipes, cables or fittings
• Creating openings in plastic panels, PVC and composite materials
• Use with hand-held drills or drill presses for renovation and installation tasks

Key specifications

• Compatible hole saw diameter range: 32–152 mm
• Shank diameter: 13 mm
• Accepts bi-metal and carbide hole saws
• Pilot drill attachment point for guided starts
• Secure locking mechanism to reduce runout and improve concentricity
• Suitable for use on metal, wood and plastic

How to use

Fit the 13 mm shank of the arbor into your drill chuck and tighten securely. Select an appropriately sized hole saw, mount it on the arbor and engage the locking mechanism according to the arbor’s instructions. Install a pilot drill bit if required to guide the hole saw. Position the pilot bit on the marked centre of the workpiece, start the drill at low speed to establish the cut, then increase speed and apply steady pressure while maintaining drill alignment to the material surface. Periodically withdraw the hole saw to clear chips and prevent overheating when cutting metal or thick materials.

Usage recommendations

Use cutting fluid or lubricant when drilling metal to extend tool life and reduce heat. For wood and plastic, use moderate speed and avoid excessive feed to prevent splintering or melting. Always wear appropriate personal protective equipment, secure the workpiece, and follow the drill and hole saw manufacturer’s safety instructions.
