The tool that draws square holes set to debut at Toolfair 2017

QUADSAW, the tool that drills square holes, will be demonstrated in public for the first time, at the Toolfair tradeshow in Harrogate, UK on 24-25 May.

Almost every construction project requires square holes for electrical sockets and other boxes but for years electricians have struggled to create them with rulers, pencils and handsaws. QUADSAW solves this problem thanks to its unique four-blade technology that cuts square holes in seconds and with absolute precision.

QUADSAW is a simple attachment to a power drill that uses patented technology to convert rotary motion into linear motion – in four planes at once. It has built-in spirit levels and the blades can be changed in seconds at the push of a button enabling the user to switch between single and double socket sizes.

The product is the brainchild of Michael Sebhatu, an Eritrean refugee turned engineer, who saw a tradesman installing electrical boxes and decided there had to be a faster, more accurate way than marking and cutting by hand.

He said: “I’m looking forward to showing people the QUADSAW in action. We think it will save construction companies a huge amount of time and money, as well as offering a perfect finish every time.”
