Modular & Solid-Carbide Drills

The new Top Drill M1 Modular Drill from Widia gives users the best of both worlds by combining the economic benefits of modular drilling systems with machining performance and hole quality comparable to solid-carbide tools. Available over a standard diameter range of 8.00 to 20.99 mm (0.3150 to 0.8264 inches), and in length/diameter ratios of 3× and 5×, drill bodies come in either flanged-shank (metric) or round-shank (inch) configurations. They feature solid coupling for consistent performance from insert to insert and easy insert changes on the machine due to a front-clamping mechanism. Inserts are offered with a UP(M) geometry in grade K20FTiAlN, featuring an application-oriented differentiated point design aimed at cost-efficient hole making in steel and cast-iron components. The modular tools offer feeds/speeds and performance levels commonly achieved with solid-carbide drills. Metal-removal rates are up to 50 percent higher than competitive modular drills while providing longer tool life and improved hole quality. Non-regrindable inserts eliminate the logistical and tool-life challenges associated with using reconditioned inserts. Widia’s new Top Drill M1 even provides an alternative to competitors’ HSS, spade and brazed drills in tough applications, allowing speed and feed increases of 40 to 50 per cent with longer tool life and improved hole quality.
