8-Piece Deep Hole Marker Set (20mm Long Nib) Waterproof Metal Marking Pen for Woodworking & DIY

Ever try to mark a spot inside a screw recess or tight joint—only to smear ink or miss the target? This 8-piece long-nib marker set is made for makers, installers, and DIYers who want clean, accurate marks in the places regular pens can’t reach. The 20mm extended tip slides into gaps, holes, and corners so you can mark the exact point the first time. With quick-drying, water-resistant ink, your lines stay readable on busy job sites and messy workbenches. Ideal as a Woodworking Marker Set for layouts, fittings, and punch/mark tasks across common materials.

Key Features

• 20mm extra-long nib reaches into deep holes, narrow channels, and hidden edges for precise placement.

• Waterproof, quick-dry ink helps reduce smudges from moisture, oil, and handling.

• Multi-surface marking for workshop and home projects (great for tile/bathroom tasks, too).

• 8-piece set keeps spares within reach—grab, mark, and keep moving.

Why Choose Our 8-Piece Deep Hole Marker Set
Standard markers are fine on flat boards, but they struggle in recesses and tight assemblies. This long-nib design reaches where a typical tip stops short—so you don’t waste time disassembling parts just to mark one point. Plus, the water-resistant ink is built to stay visible longer in real working conditions.

Perfect For
Carpenters, metalworkers, electricians, HVAC installers, DIY homeowners, furniture builds, drill-point marking, hinge/handle placement, bathroom/tile marking, and general layout work.
