Hole Saws

Hole saws cut large diameter holes in wood, plasterboard, metal and plastic.  Bi metal teeth provide long life, while carbide grit versions cut abrasive materials like tiles and fibreglass.  Pilot drill bits guide the saw and prevent wandering.

What are hole saws used for?
Hole saws are designed to cut large, clean holes in materials like wood, plastic, metal, drywall, MDF, laminates, ceramics, and tiles (when using diamond-grit types). They are commonly used by electricians, plumbers, carpenters, and DIYers for installing pipes, cable glands, locks, and light fittings.

What types of hole saws are available and how do I choose the right one?
Hole saw types include:
• Bi-metal hole saws – for wood, plastic, and general metal
• Carbide-tipped – for tougher materials like stainless steel or fiber cement
• Diamond-grit – for tiles, porcelain, and glass
• Adjustable hole cutters – for variable-size cutting in soft materials
To choose the right one, match the diameter to your job, use the correct arbor (mandrel) for your drill, and confirm material compatibility and RPM rating for safety and performance.

Do I need an arbor or pilot drill to use a hole saw?
Yes, most hole saws require an arbor/mandrel with a pilot drill bit to guide the hole saw, prevent slipping, and allow for proper chuck fitment. Some hole saws come pre-mounted, while others require a separate arbor. For large-diameter hole saws (typically over 50 mm), a heavy-duty arbor is recommended.
