Diameter Up to 6. Drilling Depth Up to 8. Standard sizes, metric sizes, and kits available. Pilot pins included up to 4 depth. See Replacement Pilot Pins. Benefits. Available in sizes up to 6 dia., 8 depth. Cutters up to 4 depth come with corresponding pilot pin. Made from premium HSS for long service life and reliable performance in demanding drilling applications. Resharpenable cutting edges deliver consistent performance across varied job site conditions. No time-consuming pilot holes and step drilling, engineered for smooth cutting action and precise hole geometry. Produces burr free holes, reducing the need for secondary finishing. Applications and Usage. HSS Annular Cutters (High-Speed Steel) are ideal for drilling holes in beams, columns, and steel plate used in construction and industrial steelwork. Perfect for onsite drilling tasks using magnetic drills, including equipment mounting, steel erection, and infrastructure work. Ideal for structural steel, mild steel, aluminum, and other common fabrication materials. Useful for repetitive holemaking in production environments where accuracy and tool life matter. Enables clean, precise holes for conduit, supports, hangers, and mechanical installations. Suitable for shops producing brackets, frames, assemblies, and custom metal components.
