13-piece HSS Drill Bit Set — Straight Round Shank Key benefits Wide compatibility: Straight round shank fits standard hand drill chucks, bench drills, radial drills and most drilling machines, so you can use this set with existing tools without adapters. Reliable performance: Made from high-speed steel (HSS) for good wear resistance and long service life, suitable for repeated use. Cleaner, faster drilling: Smooth surface and precision-ground flutes reduce friction and improve chip evacuation, producing cleaner holes with less effort. Versatile material use: Designed for drilling in metals and wood, including aluminum and iron, so one set covers a range of common jobs. What this set solves Eliminates wandering and binding: The straight round shank and precise cutting geometry help maintain stable drilling and reduce slipping in the chuck. Reduces downtime and rework: Smooth cutting and efficient chip removal create cleaner holes, lowering the need to re-drill or finish holes. Lowers tool replacement cost: HSS construction resists wear, extending bit life compared to low-grade steel bits. Features Set quantity: 13 drill bits for a range of drilling tasks. Shank type: Straight round shank for broad compatibility with drilling tools. Material: High-speed steel (HSS) for wear resistance and durability. Performance: Precision-ground blades and smooth finish for reduced friction, efficient cutting, and clean hole edges. Typical applications Metalworking: Drilling pilot holes and through-holes in aluminum panels, iron brackets, and sheet metal for fabrication or repair. Carpentry and joinery: Creating precise holes in wood for fasteners, dowels, or installations where clean edges matter. Workshop and maintenance: General-purpose drilling for assembly, mounting, and maintenance tasks using hand drills, drill presses, or radial drills. What to expect in use Fit the straight round shank into your drill chuck, secure firmly, and use appropriate speed and lubrication for the material being drilled. Expect smoother cutting and improved chip evacuation compared with lower-quality bits, with consistent hole size and appearance. Durable HSS construction supports regular use; for heavy production work, follow standard best practices for cooling and bit maintenance to maximize life.
