Marker PICA MARKER Deep Hole 150/41/SB — blue ink, refillable marker for deep holes

Deep Hole Marker PICA MARKER 150/41/SB — blue ink, refillable marker for deep holes is a refillable marking tool designed to place visible blue marks inside narrow openings and deep holes. The slim, elongated tip assembly reaches confined spaces where standard markers cannot, while the ink formulation provides clear, contrasting lines on metal, plastic, concrete and other common construction materials. The refillable body and replaceable tip reduce waste and ensure continuous use on job sites, inspection tasks and workshop operations.

Advantages

The marker combines a long, narrow tip with a reliable blue ink that adheres well to a range of surfaces and remains visible in low-light or enclosed conditions. Its refillable design lowers long-term operating costs and reduces downtime compared with disposable markers. The ergonomic barrel offers controlled handling for precise placement of marks in deep or hard-to-reach areas, and the cap secures the tip when not in use to prevent drying.

Suitable for

• Marking inside deep holes, bores and cavities
• Plumbing and pipework alignment marks
• Metal fabrication and welding layout
• Construction site measurements and inspection labels
• Maintenance checks in machines and confined assemblies

Key specifications

• Ink colour: blue for high contrast on light and dark substrates
• Tip type: slim elongated tip assembly for deep access
• Body: refillable marker housing for repeated use
• Cap: secure closure to reduce drying of the tip
• Suitable surfaces: metal, plastic, concrete and painted surfaces

How to use

Shake the marker briefly before use if recommended by the manufacturer, then remove the cap and insert the elongated tip into the deep hole or narrow opening until the tip contacts the surface to be marked. Apply gentle, consistent pressure while moving the marker to lay down a visible blue line or dot. After marking, replace the cap securely to protect the tip and preserve ink. For best results on very smooth or oily surfaces, clean and dry the area prior to marking.

Usage recommendations

Store the marker horizontally when not in use to maintain even ink distribution. Keep spare refills and replacement tips available on site to ensure uninterrupted marking capability during extended projects.
