Holemaking

Depending on your application, a number of holemaking tools may give you consistent and precise results. For some jobs, a multi-task tool or holemaking mill may do the trick, while others require a high-performance indexable bit or tap. Regardless of your business objectives, Kennametal continues to lead the industry in offering hole-making solutions using tough and durable tungsten carbide-based materials.  

At Kennametal, we have an extensive selection of state-of-the-art inserts, bits and tools for making accurate and clean holes of any diameter. These include modular and solid carbide drills, counterboring tools, hole finishers, indexable inserts and combination tools. We also offer improvement strategies and testing to help you enhance the quality of your product.
