The Milwaukee INKZALL™ Medium Chisel Black Marker (48-22-3103) is built for the demands of professional electricians, contractors, and serious DIYers who need reliable marking on the toughest job-site surfaces. Whether you're scribing conduit runs on concrete, marking junction box locations on OSB, or labelling rough framing in wet or dusty conditions, the INKZALL™ delivers crisp, fast-drying lines every time. Its clog-resistant chisel tip writes through oily, wet, and dusty surfaces without skipping, and the ink dries quickly to prevent smearing — keeping your layout marks legible from rough-in through inspection. A built-in hard hat clip means this marker is always within reach, so you spend less time hunting for tools and more time getting the job done.
