The Pica 170/46/SB Black Ink Marker For Deep Hole w/ Quiver Holder, 1-Pack is a permanent deep hole marker made for trade work where a normal marker cannot reach. This is a deep hole marker designed for precise marking on most dry surfaces. Model Number 170/46/SB. If you install hardware, lay out sheet metal, mark wood, or work around pipe and brackets, this marker gives you a clean black mark exactly where you need it.

What makes this marker different is the combination of a deep access tip and permanent ink. The 2 to 4 millimeter tip gives you enough visibility for layout marks while still staying controlled for more accurate work. Instead of switching between a standard permanent marker and a specialty layout tool, this one covers both jobs in a single body.

The reversible nib is the feature that matters most over time. When one end starts to wear, you can flip it and keep going. That means better value from each marker and less downtime when you are in the middle of installation or fabrication work. It is a practical design choice, especially for contractors who burn through markers fast.

The included quiver cap is another jobsite-friendly detail. It helps keep the marker on your belt, pocket, or tool bag so it is easy to grab and easy to stow. For layout tools, convenience matters more than people think. If a marker is not easy to carry, it tends to disappear or get left behind. This setup solves that problem.

Pica rates this marker for use on most dry surfaces, and the listed compatible materials cover the stuff pros actually run into: stone, concrete, metal, wood, dry lumber, pvc pipe, glass, wet and dry tile, dry rubber, and cardboard. That wide surface range makes it a solid fit for general construction, remodeling, mechanical work, and shop use where one marker needs to handle different materials during the same day.

Physically, it stays compact enough to carry without being too small to control. The overall length is 6.22 inches, width is 1.18 inches, and diameter is 0.67 inches. Those dimensions give you a marker that is easy to handle while still long enough to reach through hardware openings and into recessed marking points.

If you are a contractor, installer, fabricator, carpenter, electrician, plumber, or serious DIYer who regularly marks through drilled holes or around mounted parts, this is the kind of marker that earns its spot quickly. It is not just a writing tool. It is a layout tool built for real jobsite conditions, especially when access is tight and the mark still needs to be easy to see.
