Deep-Hole Marker 20 mm

This marker features a 30 mm long nib that reaches into deep holes and tight spaces where standard pens cannot. It suits carpenters, plumbers, metalworkers and DIY users who need clear reference marks on concealed surfaces. The 20 mm body diameter gives a secure grip during extended layout tasks. Ink adheres to wood, metal, glass and plastic without bleeding.

Sustained Use Performance

Quick-drying ink prevents smudging when multiple holes are marked in rapid succession. Waterproof formulation keeps lines legible on damp timber or after exposure to cutting fluids. Colour remains vivid over time so layout marks stay readable through the full project cycle. The pen continues to write consistently without skipping during long sessions.

Build Quality and Daily Handling

ABS barrel resists cracking when dropped on concrete or carried in a tool belt. Slim round nib slides through 20 mm drill holes without binding. Clip and cap stay secure during transport between job sites. No special storage orientation is required; the pen is ready to mark whenever pulled from a pocket.

Questions about this item

Does the 30 mm nib stay cool and write cleanly when marking dozens of deep holes in one session?

The 30 mm tip is made from ABS and designed for repeated deep-hole marking without overheating, and the quick-drying ink prevents smudging during continuous use.

What surface must be ready before using this 20 mm marker for the first time?

The waterproof ink works on wood, metal, glass and plastic straight from the pen; no primer or special coating is required.

Will the 1.1 inch tip fit through the chuck of a standard drill guide when marking hole centres?

The 30 mm long nib reaches through deep holes and tight spaces, letting you mark hole centres directly without removing the guide.
