CONTENTS - 10x refills (3x red, 4x grey, 3x yellow) for professional deep hole marker HDM by Hultafors in practical dispenser. PRACTICAL - The graphite refill in grey, red, yellow is very easy to replace and thanks to the practical push mechanism, it can withstand pressure up to 5 kg. This prevents the refill from being pushed in. FOR ALL SURFACES - the refill of the blue pencil is suitable for drawing on a variety of surfaces, such as wood, metal or concrete. The pencil refill writes on virtually all surfaces, even if they are moist, oily, dusty or rough. WORK MADE EASIER - The practical rollaway protection allows you to work on uneven surfaces. The teeth on the clip of the construction site pencil give it a firm and secure hold. The dispenser only releases one refill at a time, making work easier.
