Marker for deep holes Pica Pica-Ink, red — deep-hole marking ink marker

Pica Pica-Ink is a red ink marker engineered for marking in deep holes and other hard-to-reach places. The marker dispenses a vivid red ink intended to produce visible, long-lasting marks on a range of substrates where conventional markers cannot reach. It is designed for construction, installation and workshop environments to mark measurements, drill points and alignment inside drilled cavities and recessed openings.

Advantages

The marker provides a compact dispensing tip and a fluid formulation that penetrates into narrow, deep recesses to leave clear, visible marks. Its red ink offers good contrast on many materials, while the applicator allows controlled placement without the need to insert a full-length pen. The design supports one-handed use in confined spaces and helps reduce the need for temporary plugs or improvised marking tools.

Suitable for

• Marking drill points and alignment inside drilled holes and sockets
• Making visible reference marks in tight or recessed spaces during installation
• Use on construction sites, workshops and during assembly tasks where access is limited

Key specifications

• Ink color: red
• Intended application: deep-hole and recessed-area marking
• Formulation: fluid ink for narrow recess penetration
• Typical substrates: wood, metal, concrete and many common construction materials
• Applicator type: narrow-diameter tip for access into confined spaces

How to use

Extend the narrow applicator tip and insert it carefully into the deep hole or recessed area to the required depth. Depress the ink dispenser gently to apply a small amount of ink where the mark is needed. For best results, move the applicator slightly to ensure the ink contacts the substrate surface inside the recess. Allow the mark to dry before moving parts or performing further work; drying time will vary with substrate and ambient conditions.

Usage recommendations

Use the marker sparingly to avoid excess pooling of ink in the hole. Test on a representative material if substrate sensitivity or washout is a concern. Store capped in a horizontal position to maintain tip readiness and avoid prolonged exposure to extreme temperatures or direct sunlight.
