HSS step drill bit for precise hole drilling across wood, steel, metal, aluminium and plastic. Titanium-coated 4241 high-speed steel construction reduces friction and heat, delivering longer tool life compared to uncoated alternatives.
Drill holes from 4mm up to 32mm diameter without changing bits or repositioning your workpiece. The double fluted edge design enables faster, smoother cutting with automatic deburring as you work. No pilot holes or pre-drilling needed—simply align and drill.
Built from high-quality 4241 HSS material with nitrogen surface treatment for durability. The 10mm triangular round handle ensures stable grip and secure mounting in drilling tools and bench drills. Use with water cooling to further extend drill life and improve cutting performance.
Suitable for spot processing of large holes and accommodates the full range of scale sizes: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 and 32mm.
Ideal for metalwork, carpentry, fabrication and general workshop drilling tasks. Check your drill compatibility before purchase and select this bit to streamline your hole-making workflow.
