Overview:

The Silverline Adjustable Hole Cutter 447132 is a versatile, size-adjustable cutter for producing clean circular holes from 30mm to 120mm in wood, plasterboard and plastic. Its twin cutter design runs on a horizontal shaft with a central pilot drill bit to help guide the cut, making it a practical choice when you need multiple hole sizes without carrying a full set of fixed hole saws. The cutter arms are secured using a hex key fixing, and a hex key adjuster is supplied for quick setup. With a maximum cutting depth of 30mm and a recommended maximum speed of 500rpm, it’s ideal for controlled cutting in suitable materials using rotary mode only.
