Versatile hole-saw range

The Big Horn 19239 adjustable hole saw covers diameters from 40mm to 300mm in a single tool. It is aimed at woodworkers, electricians and plumbers who need multiple hole sizes without carrying a full set of fixed cutters.

Thermal and power behaviour

The accessory runs on the host drill's power, so heat and noise depend entirely on the motor used and the material being cut. No internal cooling or power regulation is built into the saw itself.

Included accessories expand utility

An extra brad-point drill bit is supplied for starting clean holes in thin sheet stock. The provided Allen wrench allows quick diameter changes on site without hunting for a separate key.

Questions about this item

How do I install the 19239 adjustable hole saw and what step is often missed?

Mount the saw on your drill, set the diameter between 40mm and 300mm using the included Allen wrench, then tighten both locking screws — the step most people miss is securing the second screw after the first adjustment.

What maintenance or replacement will the 19239 adjustable hole saw need over time?

The cutting teeth will dull with use and the brad-point drill bit may wear out; both can be replaced individually without buying a new saw body.

What limit appears first when using the 19239 adjustable hole saw continuously?

Heat buildup in the blade and drill motor becomes the limiting factor before the 300mm maximum diameter is reached, especially in dense materials.
