Widia’s Victory Top Drill M1 modular drill, part of the company’s Victory platform of advanced milling, turning and hole making tools, is said to combine the economic benefits of modular drilling systems with the machining performance and hole quality of solid carbide tools.
Available over a standard diameter range of 0.3150" to 0.8264" (8 to 20.99 mm) and at length-to-diameter ratios of 3×D and 5×D, drill bodies are available in either flanged-shank (metric) or round-shank (inch) configurations. They feature solid coupling for consistent performance from insert to insert, and a front-clamping mechanism is said to ease insert changes.
Inserts are offered with an UP(M) geometry in a K20FTiAlN grade. Also, the inserts feature an application-oriented differentiated point design for efficient hole making in steel and cast iron components, the company says.
The modular tool offers feeds, speeds and performance levels similar to solid carbide drills. According to the company, the drills increases tool life and improves hole quality while offering increased metal-removal rates. Non-regrindable inserts eliminate the logistical and tool-life challenges associated with using reconditioned inserts, the company says. The drill is also said to provide an alternative to HSS, spade and brazed drills in tough applications.
Hitting the Coolant Sweet Spot
Toolholders with integrated cutting fluid delivery channels offer threaded, fixed-position nozzles that direct parallel streams of coolant to pre-defined positions at the top of the cutting tool.
