Wet sanding system NTS 255, 250/200 mm, 200 W, 230 V

The HOLZKRAFT NTS 255 is a slow‑speed wet grinding and honing system designed for precise sharpening of knives, chisels, plane irons, axes and other cutting tools. Thanks to its low rotational speed and integrated water cooling, tools are sharpened without overheating, preserving material hardness and extending tool life.

The system is equipped with a 250 mm wet grinding wheel made of fine aluminium oxide (K 220) and a 200 mm leather honing wheel for removing burrs and polishing edges after sharpening. A powerful 200 W induction motor ensures quiet, low‑vibration operation, making it suitable for workshops, training facilities and craft use.

The powder‑coated steel housing, shatter‑proof water tank, and splash‑proof motor and switch provide durability and safe operation. The supplied accessories allow accurate angle setting and versatile sharpening, even for beginners.
