Woodworkers know that hardened glue will prematurely dull planer blades and gums drum sander paper, so a quality wood glue scraper is necessary for any workbench. A bench grinder also does the job, but extensive time and concentration is required – honestly, it’s largely advantageous to replace instead of re-sharpen. Despite the name, this tool looks more akin to a drill bit than a saw – in fact, its cutting edge rests at the end of a large diameter cylinder, and this is spun on a power drill to cut through your chosen material. That covers the basics, but what if you need to drill holes deeper than your hole saw allows or widen an existing hole? Their function is to create a pilot hole, anchoring the hole saw in place to decrease any ‘wandering’ as the cut is made.

Also known as a hole cutter, and sometimes spelled ‘holesaw’, the hole saw is easy to understand but deceptively tricky to master. Blades with a lower TPI cut faster, but they do tend to tear at fibres to produce a more ragged edge. It’s the type of tool bit used to grip other moving tool components, essentially the connecting part between your hole saw and your power drill.

When using a more powerful drill to cut through a tougher material, the machine may experience ‘kick back’; under such conditions, you’re well advised to use a drill with a side-handle to afford additional stability and control.
