Frequently Asked Questions

What is the 54mm holesaw used for?

A 54mm holesaw is a common choice for plumbing penetrations around 50mm pipe, for vent and grille openings, and for cable entries that sit between the smaller electrical sizes and the big duct sizes. It is a useful all rounder for plumbers and electricians.

Is 54mm a standard plumbing knockout?

It is in the family of sizes used for drainage and vent pipe penetrations, giving a hole that clears a 50mm pipe with a little room to spare. If you are chasing a specific fitting, check the outside diameter of the pipe or duct you are running.

What is the best way to cut sheet metal with this saw?

Mark the centre, start the pilot, and let the rim begin cutting at low speed before feeding normally. Keep the drill square and use a lubricant. Back the saw out to clear swarf on deeper cuts, and ease right off as the teeth break through.

Can this saw cut timber framing?

Yes. It cuts through timber studs, joists and plywood cleanly, which is handy when you are chasing pipe or cable through a floor or wall cavity. Use a steady feed and let the saw do the work; timber cuts much faster than steel.
