step drill for sale
A step drill represents a versatile cutting tool designed for creating precise holes of varying diameters in multiple materials. This professional-grade instrument features a unique stepped cone design that allows users to drill different sized holes with a single bit, eliminating the need for multiple conventional drill bits. Modern step drills are crafted from high-speed steel or cobalt steel, often enhanced with titanium coating for superior durability and heat resistance. The cutting edges are precision-ground to ensure clean, accurate holes without burrs or rough edges. These drills typically range from 1/8 inch to 1-3/8 inch in diameter, with clear size markings etched onto the surface for easy reference. The self-starting tip prevents walking or wandering during initial contact, while the fluted design efficiently channels debris away from the cutting surface. Step drills excel in working with sheet metal, plastic, wood, and thin aluminum, making them indispensable in automotive work, HVAC installation, electrical projects, and general construction applications. The hex shank design ensures secure fitting in both standard and quick-change drill chucks, preventing slippage during operation.
