The solid-carbide Universal Drill from Niagara Cutter combines a multi-purpose geometry with advanced coating technology to provide reliable, predictable tool life and a lower cost per hole, especially in high-volume production environments. The drill’s rigid, four-facet point geometry provides good centering capability tolerance and is easy to regrind, according to the company. A polished aluminum-chromium-nitride coating gives the drill high abrasion resistance, toughness and good chip evacuation capabilities. Well-suited for hole-making applications in a variety of workpiece materials, including steels, stainless steels and cast irons, the Universal Drill’s versatility can reduce required tooling inventories.
Available drill diameters range from 3 to 20 mm in increments of 0.1 mm. For efficient chip evacuation, the 5×D- and 3×D-length drills with cylindrical shanks offer the option of through-tool coolant. All of these drills are compatible with Seco shrink-fit toolholders, hydraulic chucks and high-precision collet chucks.
