Yato YT-69931 writing chalk 12 pc(s)

Yato YT-69931 writing chalk set contains 12 white sticks designed for marking on a variety of surfaces including metal, wood, stone and concrete. Each stick is approximately 120 x 12 mm and manufactured in a gum-based composition that leaves clear, durable marks suitable for technical and construction applications. The pack is intended for professionals and hobbyists who need reliable, visible lines for cutting, welding, measuring and layout tasks.

Advantages

The gum-based formulation provides strong adherence to smooth and rough surfaces, reducing smudging and improving mark visibility in dusty or rough environments. The uniform dimensions ensure consistent handling and line thickness, while the compact pack of 12 offers convenient storage and replacement frequency for workshops or job sites. White pigment offers high contrast on darker materials, making it suitable for a wide range of materials and conditions.

• Marking metal sheets and pipes prior to cutting or welding

How to use

Hold the chalk stick like a pencil and apply firm, even pressure to produce a clear line. For precise marks, use the edge of the stick; for broader lines, press the flat face against the surface. On very smooth or oily surfaces, clean the area first to improve adhesion. Replace sticks from the pack as they wear down; store unused sticks in a dry place to maintain consistency.

Usage recommendations

Use the white gum chalk for temporary markings that need to be visible but removable; avoid using on freshly painted surfaces where pigment transfer is a concern. For best results on metal, wipe the surface to remove oil and dust before marking. Keep away from moisture to prevent degradation of the gum binder.
