Precision you can measure. Consistency you can repeat.

Conko is a carbide cutting tool brand created specifically for international markets. Established in 2026, Conko may be a new name, but we are not a company starting from scratch.

Behind the Conko brand is Changzhou Huarui Tool Co., Ltd., a carbide cutting tool manufacturer established in 2011. This manufacturing foundation gives Conko the technical experience, production capability and quality control needed to serve professional buyers worldwide.

We are a manufacturer, not a trading company. From incoming carbide rods and precision grinding to fluting, coating, inspection, packing and dispatch, every stage is completed in our own workshop.

We work with overseas tool distributors, machine shops and manufacturers that purchase cutting tools directly for parts production. Our product range focuses on solid carbide cutting tools, including four-flute square end mills, ball nose end mills, corner-radius end mills, three-flute end mills for aluminum, carbide drills and chamfer mills. We also manufacture diamond-coated cutters for dental CAD/CAM applications and supply solid carbide rods.
