ChalkShot provides a quick and easy, high visibility, non-permanent marking solution when drilling blind holes on hard to mark surfaces. The applicator shoots chalk on to the surface to be marked – there is no tip or pen nib to get damaged or clogged or dry out over time. The chalk is high vis green and sits on top of the surface for the best visibility. It even works on grease, dirt, and rust covered surfaces. Uses a marking dye that is non-permanent, environmentally friendly, and wipes off easily if a mark needs to be moved. It is also long lasting – one unit can mark over 250 locations without drying out!
