HSS Drill Bits are widely used cutting tools designed for drilling metal and other suitable materials in industrial, workshop, manufacturing, and maintenance applications.
High-speed steel provides a practical combination of hardness, toughness, heat resistance, and wear resistance, making it suitable for repeated drilling operations under appropriate cutting conditions.
Kaining Tools manufactures a range of HSS drilling tools, including Twist Drill Bits, Straight Shank Drill Bits, Silver & Deming Bits, Taper Shank Drill Bits, Step Drill Bits, Center Drill Bits, and Double End Drill Bits.
With an integrated manufacturing system, selected materials, precision processing, mature heat-treatment technology, and final inspection, Kaining Tools supports both standard products and customized drilling-tool requirements.
KEY FEATURES
HIGH-SPEED STEEL CONSTRUCTION
Selected high-speed steel provides hardness, toughness, wear resistance, and reliable cutting performance for general industrial drilling applications.
CONTROLLED HEAT TREATMENT
Mature heat-treatment processes help improve hardness, wear resistance, strength, and overall tool durability.
PRECISION CUTTING GEOMETRY
Accurately processed drill points, cutting edges, and flute structures help support stable penetration, consistent drilling, and reliable hole quality.
EFFICIENT CHIP REMOVAL
Optimized flute structures help evacuate chips from the cutting area and support smoother drilling performance.
WIDE PRODUCT RANGE
Multiple HSS Drill Bit designs are available for different hole sizes, drilling equipment, workpiece materials, and industrial applications.
CUSTOM MANUFACTURING OPTIONS
Custom diameters, lengths, shank structures, cutting geometries, materials, surface finishes, product markings, branding, and packaging can be supplied according to confirmed customer requirements.
TYPES OF HSS DRILL BITS
TWIST DRILL BITS
General-purpose drilling tools with spiral flutes for efficient chip removal and stable metal drilling.
STRAIGHT SHANK DRILL BITS
Designed with cylindrical straight shanks for convenient clamping in compatible standard drill chucks.
SILVER & DEMING BITS
Reduced-shank drilling tools designed for larger-diameter holes while fitting compatible standard-capacity drill chucks.
TAPER SHANK DRILL BITS
Designed for secure mounting in compatible machine tools and stable drilling in demanding industrial applications.
STEP DRILL BITS
Multi-diameter drilling tools designed for drilling, enlarging, and deburring different hole sizes with a single tool.
CENTER DRILL BITS
Short, rigid drilling tools designed for accurate center-hole preparation and precise positioning before machining.
DOUBLE END DRILL BITS
Compact drill bits with cutting points at both ends, providing two usable drilling ends and high rigidity.
