Marxman Pen Marx-1-1 Hole Marking Tool

Sometimes a tool comes along, that just does exactly what it's supposed to. This Marxman hole marker is one. Apparently, it was originally, a Dragon's Den project. That passed me by, but it has now become an essential part of my tool box. Some reviews mention that when they tried to use it nothing happened, and they had to send it back. It is possible that they did receive a duff one, but be aware, chances are, that when you receive yours, it will be in the 'locked' position. You have to twist the end, so that the plastic rib, lines up with the notch. Only then will it fire (Photo). Operation is simple. Just line up the nozzle with your hole and push down. You will hear a small whoosh of air, and that's it. This standard model is good for holes upto 45mm deep. There is a deep hole model for deeper holes, if you need it. The mark itself is a circle of green chalk. It looks like fluorescent paint, it's that bright, but it easily wipes (washes) off of surfaces. The manufacturers say each unit is good for approx 250 holes. I can't verify that, but they certainly last a long time. I have included a short video of me using it with a metal clad back box. The holes aren't deep, but quite often these are fitted to uneven walls, and trying to mark conventionally with a pen/pencil can be extremely difficult. Originally, they were £ 10.00 each. But, now that they halved in price to £ 5.00, they represent great value, even for occasional DIY use. Overall, I can't recommend this enough. On internal, nice white walls there are occasions where I still use a Pica marker, but for all other scenarios, this is unbeatable. I hope you found this review helpful.

Awesome idea in a great tool. The Marxman pen shoots a tiny amount of bright green chalk directly at the spot where you need to drill a hole. Each cartridge has about 300 shots in it, so lasts quite a while and is excellent value for the price. The bright green spots it leaves are very easy to spot, and if you use it right, it marks with an "X". Sometimes if your drilling a hole to attach wood to a wall, it can hard to mark the spot with a pen or pencil due to the depth of the wood. Not so with this device. I've yet to encounter a point where it couldn't or didn't mark the drill point accurately. Buy it and you won't be disappointed.

Love these pens for jobs, leave a super accurate mark for drilling etc and ink is really bright so you can actually see it !!

Certainly ok but doesn't make as clear a mark as I had hoped.

Awesome product. Does exactly what it says. Would never be without one of these in my toolbox. Buy one. You won’t regret it.

Brilliant product. After using a pencil on brick to mark holes then not being able find the mark you made, this is perfect. Small easy to use. One press leaves a bright green mark which is super easy to see. Has a twist lock on the nozzle so that it won’t go off in your pocket or tool bag. Not cheap but worth the money. Will definitely be buying another one, when my current one runs out.

This was recommended to me by a guy who came to do some tiling, so I thought if it's good enough for a professional, it'll do for me. He was right! This is a brilliant idea, making it much easier to mark drill holes especially in thicker items that you struggle to get a pen/pencil through. It's not at all expensive considering it should last a decent length of time, and it's now an indispensable item in my toolbox.

A must have for any diy er. Excellent especially on brick.
