USA — The new FBX drill is the first step in a three-part tooling concept offered by Kennametal. The series includes the Harvi Ultra 8X and the Harvi end mill series, 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.
The FBX drill speeds up the machining process by combining the advantages of a flat bottom drill and a z-axis plunge mill. The flat bottom design eliminates radial forces while four effective cutting edges provide increased feed and speed rates, leading to up to 200 % higher metal removal rates than traditional ramping techniques and freeing up capacity for aerospace manufacturers, the manufacturer states. 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 a long and short version (150 mm and 95 mm). This modular drill connects to Kennametal’s bolt taper flange (BTF) mount adapters, available in various spindle connection styles. The design of the FBX flat bottom drill directs cutting forces into the machine spindle, minimizing deflection while increasing tool life and metal removal rates.
The drill is suited for drilling into solid, chain hole drilling and plunging in a variety of materials such as high temperature alloys, stainless steel, and steels and cast irons. It is equally suitable for similar applications for the general engineering and power generation markets.
