About Harttek
Specialized solutions and technical services for cemented carbide button bits.
Our Story
Harttek was founded by Eric Lau, who brings over 20 years of hands-on experience across the cemented carbide value chain — from tungsten raw materials and powder metallurgy to finished button bit products.
That depth of knowledge enables Harttek to serve as more than a supplier. We function as a technical partner, helping customers select the right carbide grade and button geometry for their specific drilling conditions.
