Product Information
Full details
The DART 165mm Bi-Metal Holesaw is a high-performance cutting tool designed for professional contractors and serious DIY enthusiasts who require clean, precise holes in a wide variety of materials. Its standout benefit is the variable pitch tooth design, which facilitates aggressive material penetration and efficient swarf removal for both thin and thick gauge surfaces. While it excels in versatility across metals, wood, and PVC, users should note that as a large 165mm diameter saw, it requires a powerful drill and steady technique to achieve optimal results without binding.

FAQs
Can I use this holesaw with an impact driver?
No, it is recommended to use this with a standard corded or high-torque cordless drill. Impact drivers can damage the teeth and the arbor connection.
Is this suitable for stainless steel?
While it cuts various metals, stainless steel is extremely hard and may significantly reduce the lifespan of the bi-metal teeth. If cutting stainless, use very low speeds and plenty of cutting lubricant.
What is the maximum depth I can cut?
The maximum cutting depth for this model is 38mm.
Does this product come with an arbor?
The DART 165mm Holesaw is typically sold as the saw blade only; please ensure you have a compatible arbor assembly for this size.
How do I ensure a clean cut in wood?
Drill halfway through from one side until the pilot bit emerges, then finish the cut from the opposite side to prevent wood splintering or 'blowout'.
Troubleshooting
Holesaw binding or stalling in material
Reduce your drilling speed and apply consistent, lighter pressure to allow the teeth to clear chips effectively.
Excessive vibration during operation
Check that the arbor is securely locked and the drill is held perpendicular to the surface; ensure the workpiece is firmly clamped.
Teeth clogging with material
Stop drilling periodically to clear away swarf and verify that you are not using a feed rate that is too aggressive for the material thickness.
Pros and Cons
Pros
- Versatile performance across both metal and wood substrates
- Variable pitch design minimizes chatter and provides a cleaner finish
- Efficient chip and swarf ejection prevents stalling
- Highly durable bi-metal construction maintains edge sharpness
Cons
- Large 165mm diameter requires a drill with high torque or a low-speed setting
- Requires careful alignment due to its significant cutting surface
- Not suitable for impact drivers; must be used with a standard chuck-compatible drill
Setup, Compatibility & Care
To use the DART 165mm holesaw, mount it securely to a standard heavy-duty drill arbor compatible with this diameter. Ensure your drill chuck is tightened correctly before starting. Compatibility is extensive, spanning most portable and drill press equipment capable of handling large-diameter accessories. After use, clear out any packed debris or metal shavings from the gullets using a stiff brush. Store in a dry environment to prevent surface oxidation on the metal body, and apply a light coat of machine oil if storing for extended periods.
