Standard Marxman – Box of 30 – 13ml

The Marxman standard hole marker is one of those tools that sounds almost too simple until you use it on site and wonder how you managed without it. Push the tip into a fixture hole, press, and a burst of bright green chalk lands exactly where the drill needs to go. No pencil squinting through holes, no pilot punch guesswork, no fixtures that shift while you are marking through them. Just a clean, accurate chalk dot and you are done.

It works at depths up to 50mm, which covers the vast majority of surface-mounted fittings, brackets, back boxes, and frame fixings you will encounter day to day. The chalk is bright green and visible on most surfaces, and because it is chalk it brushes off cleanly once the fixing is in. No residue, no staining, no hunting for the marks later because they are invisible.

Where the Marxman Hole Marker Earns Its Keep

Originally seen on BBC’s Dragon’s Den, the Marxman went from concept to site staple pretty quickly. Electricians use it for back boxes and consumer units. Joiners use it for hinges and lock keep plates. Plumbers use it for pipe clips and bracket plates. If there is a pre-drilled hole and a surface behind it that needs a corresponding mark, the Marxman does the job faster than any alternative method you can think of.

Each pen gives approximately 250 bursts, which is a reasonable run for a busy fixer on a decent-sized job. The chalk refills the marker zone automatically between uses, so there is no pumping or priming required. Designed and manufactured in the UK, the tool itself is well made and fits naturally in a tool belt pocket or a trade bag side pocket.

Sold here in a box of 30, this is the sensible buy for trade use, stocking the van, or supplying a team where tools tend to walk off on their own.
