Deep-Hole Marking Reach

This set supplies eight long-nib marker pens, each fitted with a 20 mm tip that reaches into deep holes, cracks and confined spaces. A built-in 6 cm ruler on the barrel aids accurate placement. The pack suits carpenters, metal fabricators, glaziers, auto technicians and DIY enthusiasts who need permanent, fade-resistant lines on wood, metal, concrete, plastic, glass and aluminium. Colours provided are black, red, green and blue, two of each.

Surface And Compatibility Check

Verify that the target surfaces are clean and dry before marking, as the waterproof, smear-resistant ink performs best under those conditions. Confirm that the 20 mm nib diameter can physically enter the holes or gaps you intend to mark. Ensure the four supplied colours meet your coding or identification needs, because no other shades are included in the pack.

Sustained Jobsite Use

The premium PP plastic barrel withstands repeated jobsite handling and the fine tip maintains crisp lines over extended marking sessions. Waterproof, fast-drying ink remains legible on most materials without smearing when exposed to moisture or friction. Responsive customer support is available within 24 hours if any pen fails to perform during prolonged projects.

Questions about this item

What comes in the 8-piece pack and do I need to buy anything extra to start marking?

The box contains eight long-nib markers — two each in black, red, green and blue — with built-in 6 cm rulers. No extra items are required; the pens are ready to use on wood, metal, concrete, plastic, glass or aluminium.

Which colour should I choose for the best visibility on dark metal and concrete?

The set includes black, red, green and blue ink. Lighter colours such as red, green or blue show up more clearly on dark metal or concrete, while black works well on pale surfaces.

How does the 20 mm nib perform when marking inside a deep drilled hole?

The 20 mm extra-long nib reaches into deep holes, cracks and tight spaces, while the fast-drying waterproof ink lays down permanent, smear-resistant lines on clean, dry surfaces.
