For flat-bottom drilling of structural aerospace parts, the patented FBX drill delivers superior stability and up to 200% higher metal removal rates when machining high-temperature alloys, stainless steel, and other materials. The modular drill is the first step in a three-part tooling concept—including the HARVI Ultra 8X and the HARVI end mill series—specifically designed by Kennametal to decrease cycle time for these types of applications.
The FBX drill is part of a tooling concept specifically developed to maximize metal removal rates and decrease cycle times when machining aerospace structural components. Quickly removing large amounts of material remains a challenge for these types of components. Traditionally, the first process step is to enter the material by using ramping techniques. This is a time-consuming process and low metal removal rates are the norm. Once the drill has shaped the basic structure of the component, roughing and finishing with indexable and solid end mills are the next process steps.
Four effective cutting edges provide stability in challenging applications like chain hole drilling, while large chip flutes ensure a hassle-free chip evacuation. Supported by a series of exchangeable coolant nozzles to help eliminate heat buildup, the drill point is characterized by a center insert with two effective cutting edges and chip splitters for maximum feed capabilities. The drill bodies are available in diameters 60, 75, and 90 mm, and come in long and short versions (150 and 95 mm). This modular drill connects to Kennametal’s bolt taper flange (BTF) mount adapters, available in various spindle connection styles.
