About HSS Twist Drill Bits
As a specialized HSS drill bit manufacturer based in Hangzhou, China, Wryno Global produces high-speed steel twist drill bits engineered for consistent performance across general-purpose drilling applications. Our HSS drill bits are manufactured from premium high-speed steel (HSS 4341 / HSS 6542), delivering the hardness and heat resistance required for drilling through mild steel, aluminum, brass, wood, and plastic materials.
The twist drill bit is the most widely used drill bit type worldwide, and our manufacturing line covers the full range — from micro-diameter precision bits to large-diameter industrial bits. Each HSS twist drill bit features a precisely ground 118° or 135° point angle, optimized flute geometry for efficient chip evacuation, and surface treatment options (black oxide, bright, or TiN-coated) to match your market requirements.
Whether you need standard DIN 338 jobber-length bits, DIN 1869 extra-long bits, or custom OEM specifications with private labeling, our factory can deliver. We support bulk orders with MOQ starting from 500 pieces per size, and offer competitive factory-direct pricing for importers, distributors, and OEM buyers worldwide.
