Product description
- 11-Step Sizes for 6-24mm Hole Diameters in One Bit With 11 precision steps 6, 8,10 24mm), this drill bit replaces 11 individual bits, letting you drill or expand holes effortlessly in stainless steel brackets, cast iron machinery parts, copper busbars, and aluminum alloy frames. Ideal for industrial maintenance, automotive repairs, and electrical installations, it saves up to 30% more time by eliminating frequent bit changes
- 118 Split Point & Spiral Flute for Precision & Efficiency The 118 X-type cutting tip self-centers to eliminate wandering, allowing precise hole starts without a pilot hole even on uneven surfaces of stainless steel pipes or cast iron fixtures. The spiral flute design efficiently evacuates metal shavings from copper plates, aluminum panels, and thin steel sheets, preventing clogs and delivering burr-free holes in half the time of traditional drills
- Universal 1 4" Hex Shank for Tool Compatibility The 6.35mm hex shank fits securely in all standard drills, impact drivers, and bench drills no slippage during high-speed operation on hard metals like stainless steel or soft metals like aluminum. It works seamlessly with cordless drills, drill presses, and hand tools, making it a versatile choice for professional workshops and DIY projects alike
- Multi-Material Mastery for Diverse Metalworking Needs Engineered for hard metals (stainless steel, cast iron, spring steel) and soft metals (copper, aluminum, brass), this step bit handles thicknesses from 1mm (copper foil) to 5mm (stainless steel plate) with consistent precision. Perfect for metalworkers, electricians, and DIY enthusiasts tackling projects from stainless steel kitchen installations to aluminum sheet metal fabrication no need for multiple tools
