Description

Marks Deep Holes

Hits the center of the hole without dragging a pencil around the surface. Marks through drilled holes up to 250 mm deep.

360 Degree Spray Arm

The swivel spray arm helps you mark in tight spots where you cannot get a straight shot, like cabinets, framing pockets, and behind mechanicals.

Refillable, Long Run

Chalk-based dot marking with up to 1,500 shots per fill, plus a long-life pump mechanism that marks without aerosol gas.

Pica 2020 Deep Hole Spray Marker, 1-Pack Overview

The Pica 2020 Deep Hole Spray Marker, 1-Pack is a marking tool designed for contactless layout through drilled holes when a pencil, scribe, or marker tip cannot reach. This is a deep-hole spray marker designed for transferring hole locations quickly and accurately on real job materials.

The big win is depth and accuracy: it can mark through drill holes up to 250 mm (25 cm / 10 in) deep, helping you transfer a hole center without guessing or widening the hole just to fit a marker. The chalk-based spray makes a green fluorescent dot that is easy to see while you are lining up anchors, dowels, plumbing penetrations, or electrical pass-throughs.

Because it is a spray burst, it can create a more complete “footprint” of the drilled hole location instead of just a faint edge mark. That matters when you are drilling the mating part and need the hole location to be obvious and repeatable.

The 360 degree spray arm is there for the spots that slow you down: inside a cabinet, between studs, near conduit, or against a wall where you cannot hold a straight marker body inline with the hole. Rotate the arm, line it up, and mark without fighting tool clearance.

This marker is built for jobsite use, with dust and moisture protection and adhesion on a wide range of surfaces including dry, damp, rough, and smooth. When you are done, the marking is designed to be easy to remove from smooth surfaces, which is useful when you are working on finished materials and want less cleanup time.

For cost of ownership, it is refillable for long-term use and rated for up to 1,500 shots. The “zero gas” pump mechanism means it marks without an aerosol propellant, so it is a straightforward, hand-powered solution for layout work.

If you do wood, electrical, plumbing, or general construction layout where hole transfer comes up all the time, this tool is made to speed up that step and reduce rework from misaligned holes.

• Tool Type: Marking tool (deep-hole spray marker)
• Primary Use: Contactless marking through drilled holes for accurate hole transfer
• Power Source: Manual pump (no aerosol gas)

• Works across drill hole sizes from 3 mm
• Helps reduce layout time when you are doing repetitive hole transfers

Marks through deep drill holes

If you have ever tried to transfer a hole location through a thick member, you know the struggle. This tool is built specifically to mark through depth, not just around the rim.

• Precise markings through drill holes up to 250 mm deep
• Designed for full-surface imaging of the drill hole location
• Adheres to surfaces that are dry, damp, rough, or smooth

High-visibility dots, long run

The chalk-based mark is bright and easy to see while you are lining up the next step. The pump mechanism is rated for lots of cycles, and the marker is designed to be refilled instead of tossed.

• Up to 1,500 shots
• Refillable for long-term use

Pro Tip

For the cleanest hole transfer, keep the spray arm centered in the drilled hole and give one quick pump. On smooth finished surfaces, wipe the chalk mark soon after layout so it comes off easier.

Tool Nut’s Take

The fast way to transfer holes

The Pica 2020 Deep Hole Spray Marker, 1-Pack is the kind of niche layout tool you buy once and then wonder why you waited, especially if you do installs where holes need to line up the first time.

• Who it’s for: Electricians, plumbers, and carpenters doing hole transfer work through thick materials or tight access spots.
• Why it stands out: Deep marking reach (250 mm) with a 360 degree spray arm, so you can mark where a regular marker cannot physically fit.
• Worth knowing: The marking is chalk-based and high visibility; it is designed to adhere across a lot of surface conditions and be easier to remove on smooth surfaces.
