Bold, reliable marks - with a 6.5mm x 2.7mm graphite core
A wide graphite core lays down a heavier line than standard pencil leads, making marks clear on rough timber and plasterboard. Core dimensions indicate a substantial diameter that resists crumbling under pressure.
Visible, consistent lines speed up measuring and cutting and reduce the need to retrace marks.
Fewer breakages on site - with a hardwood outer casing
Hardwood surrounding the graphite adds structural strength and helps prevent snap fractures during aggressive marking or when pressed against hard edges. The outer material absorbs side stresses that typically break standard pencils.
Greater durability means fewer replacements and less interruption when working at height or in awkward positions.
Choice of mark darkness - thanks to Medium and Hard grades
Two hardness grades are colour coded for quick identification, with Medium offering darker marks and Hard producing firmer, crisper lines. Colour coding uses red for Medium and green for Hard.
Select the grade suited to layout or cutting needs without guessing the pencil hardness on a busy job.
