HSS Twist Drill Bits
HSS twist drill bits for application-matched metal drilling, maintenance and OEM orders. Specify the workpiece, diameter, length and shank so the material grade and point geometry can be confirmed.
HSS Drill Bit Selection
Choose HSS Twist Drill Bits by Material, Size and Coating
HSS twist drill bits are the default choice for mild steel, aluminum, wood, plastic and general workshop drilling. The right quote depends on steel grade, point angle, coating, shank and packaging level.

About HSS Twist Drill Bits
Wryno supplies HSS twist drill specifications for general metal drilling and OEM procurement. Start with the workpiece and required hole rather than choosing only by a coating name.
For mild steel and non-ferrous applications, confirm the HSS grade, point geometry, flute length and surface treatment. Stainless steel and heat-sensitive drilling may call for a different grade or cutting strategy; compare HSS and cobalt drills before ordering.
Metric, fractional, number and letter sizes are distinct nominal systems. Use the drill size chart as a reference and send the exact required size. Availability, tolerances, MOQ and lead time are quotation-specific.
Applications & Materials
Mild Steel Drilling
Ideal for drilling mild steel plates, tubes, and structural components. HSS drill bits handle standard steel drilling with reliable performance.
Aluminum & Non-Ferrous
HSS twist drill bits work well on aluminum, copper, and brass. Sharp point angle reduces grab and delivers clean holes.
Wood & Plastic
Versatile HSS drill bits for wood, MDF, plywood, and plastic materials. Suitable for construction and DIY applications.
General Maintenance
Essential for maintenance workshops and repair operations. A cost-effective choice for general-purpose drilling needs.
Technical Specifications
- Diameter: specify the exact metric, fractional, number or letter size.
- Length: flute length and overall length; identify jobber, stub or long-series requirements.
- Shank: straight or reduced shank, with holder dimensions.
- Point: request the required point angle and split-point preparation; confirm against the application.
- Surface: confirm bright, oxide or coated requirements with the selected grade.
