Tracer Marking Kit with Deep Hole Pencil, Lead Set and 2 Clog Free Markers

The Tracer AMK4 marking kit solves the deep hole marking problem that standard pencils can’t touch. Up to 145mm deep in a 6mm width hole — that’s nearly 6 inches of marking depth for electrical conduit runs through studs and joists. Up to 100mm deep in a 3mm width hole for tighter spaces. The complete kit delivers specialized marking capability that electrical contractors, plumbers, and HVAC techs need when running lines through framing.

This kit shines in log home construction, metal fabrication shops, and anywhere dust and oil make standard markers useless. The AMK4 kit is noted for its value as it bundles both the mechanical pencil and specialized clog-free markers, whereas many competitors sell these separately.

Deep Hole Marking That Actually Works

The marking depth specs tell the story. Up to 100mm deep in a 3mm width hole means marking pilot holes for wire runs without losing your pencil in the cavity. Up to 145mm deep in a 6mm width hole handles the deeper penetrations needed for plumbing and HVAC rough-ins.

Specification	Value
Maximum depth (6mm hole)	145mm
Maximum depth (3mm hole)	100mm
Lead type	2B graphite replacement leads (6 pieces included)
Marker tip size	1-2mm bullet-point
Weight	0.5 lb

The fully extendable lead for marking blind holes means no more guessing where that hole emerges on the other side of a beam. The integrated in-built sharpener located in the pencil cap keeps lines precise without hunting for a separate sharpener.

Its ability to mark on a wide variety of surfaces—including concrete, brick, wood, metal, and even shiny or dusty surfaces—is highly valued, especially given its deep hole marking capability up to 100mm or 145mm depending on the hole size. That versatility matters when you’re switching between materials throughout the day.

Markers That Don’t Quit on Dusty Surfaces

Standard markers clog within minutes on dusty lumber or oily steel. The clog-free markers designed to mark through dust and oily surfaces without clogging solve that problem. 1-2mm bullet-point tip delivers clean lines whether marking fresh-cut lumber covered in sawdust or greasy equipment parts.

Works on metal, steel, concrete, drywall — the surface versatility contractors need. Additionally, it contains two clog-free permanent markers (black and red) that perform well on dusty surfaces without clogging, suitable for marking on tiles, concrete, brick, glass, and shiny surfaces. Red for hot, black for everything else. Simple system that works.

Complete Kit Components

1 x Tracer Deep Hole Construction Pencil (with built-in sharpener) 1 x Replacement Lead Set (6 x 2B graphite leads in anti-snap dispenser) 2 x Tracer Clog-Free Permanent Markers (1 Black, 1 Red) 4 x Tracer Site Holsters (for pencil, lead set, and both markers)

The Tracer Site Holsters included for every component to allow easy storage on-site and belt attachment matter more than they should. Tools that stay on your belt get used. Tools in the truck don’t. Four holsters mean everything has a home.

The anti-snap dispenser for replacement leads prevents the most common field failure — broken leads in your pouch. Maintenance includes sharpening the pencil lead using the built-in cap sharpener and replacing leads via the extendable mechanism. Standard 2B replacement leads are compatible with the pencil.

Users often choose Tracer for its holster system and marker performance on dusty surfaces. That’s the real-world feedback that matters — not marketing claims but what contractors actually value after months of use.
