Put down the pencil and pick up Marxman''s deep hole pen. This tool clearly and accurately marks a fixing point on your workpiece with a bright green dot. It will work on most materials, including brick, wood, metal, ceramic, porcelain and pebbledash, so you''ll be ready to cut or drill with precision on a variety of jobs. This pen dispenses 250+ bursts of green pigment, so you only need one in your toolbox to see you through plenty of drilling and mounting tasks. Using it is easy too, as all you need to do is push it on the surface and it will leave a single dot with no runs. The fluorescent colour means you''ll be able to see it clearly, even at a distance. This makes it particularly useful when inspecting overhead work surfaces at floor level, such as roof beams or a ceiling. • Suitable for marking a fixing point through various diameters and depths from 45mm to 100mm • Use on materials including stone, brick, wood, metal, ceramic, porcelain, pebbledash • Ideal for specialist jobs such as fixing fence posts • 250+ bursts of fluorescent green pigment in every pen • Easy to remove

Gives quite a thick cross shape dry powder mark so it’s good for drilling in brick and external wood etc. I don’t think it would be suitable for fine precision work where a smaller mark would be required i.e. cabinet making etc.

Great for me as been electrician for marking through back boxes and anything else I need to fix to walls at home and work. There are 2 different ones. 1 is for upto 50mm holes and 1 for upto 100mm holes makes marking where you need to drill very easy.

Works well and is more accurate than I thought it was going to be. Just hope it lasts for as long as it states.
