Pica Powder Deep Hole Spray Marker PICA2020 – High-Vis Green Chalk, 3mm–25cm, 1,500 Shots

Meet the Pica Powder Deep Hole Spray Marker PICA2020, a precision tool built for professionals who need clear marks in tight spaces. It emits bright, green-fluorescent chalk through drill holes as small as 3 mm and up to 25 cm deep. The result is a high-visibility line that helps you align, verify, and plan with confidence, without direct contact with the work surface.

Designed for one-handed use, the marker features a 360° spray nozzle that reaches around corners and into awkward spots. The refillable cartridge extends the tool’s life, delivering up to 1,500 marks per fill, so teams can keep moving without frequent interruptions. The chalk is formulated for vivid contrast on a wide range of materials, from wood to metal to plaster, making it a flexible choice for construction, electrical, plumbing, and engineering tasks.

Core benefits at a glance

• Through-hole marking: works through drill holes up to 25 cm deep with sharp visibility.
• All-diameter compatibility: marks through hole sizes starting from 3 mm for versatile use.
• One-handed control: quick, deliberate spraying with minimal tool handling.
• Long-term use: refillable cartridge system supports up to 1,500 marks per fill.
• Moisture and dust protection: designed to withstand dusty or damp sites without premature failure.

The marker adheres to a wide range of surfaces—dry, wet, rough, or smooth—and the chalk can be removed from most non-porous surfaces when needed. In practice, technicians appreciate how it clarifies hole locations before drilling, capturing the moment when a mark is made and keeping it visible as work proceeds. For professionals who need rapid alignment verification, this marker offers a practical balance of clarity, durability, and ease of use.

Use cases and scenarios

• Construction: verify alignment behind fixtures or within framed cavities, then confirm before drilling or cutting.
• Electrical and plumbing: mark through conduit holes or access points while maintaining control with one hand.
• Engineering and fabrication: annotate components in tight assemblies where space is limited.

Care and longevity

• Keep the nozzle free of obstructions; store in a dry environment for best performance.
• Refill when the 1,500-mark lifespan becomes apparent to maintain consistent visibility.
