Gühring 9501 HSS Spiralbohrer StepPower Drills Set (Made in Germany)

HIGHLIGHTS:

The Gühring StepPower HSS-TiN Twist Drill (9501) is a premium, titanium-coated drilling solution engineered for maximum tool life and superior speed in manual applications. Featuring a revolutionary multi-step tip geometry, this drill acts as its own pilot bit, gradually enlarging the hole to ensure perfectly circular, burr-free results even in thin-walled materials. The addition of a Titanium Nitride (TiN) coating significantly increases surface hardness and heat resistance, making it the ideal choice for high-volume drilling and tough steel alloys.

Specifically optimized for cordless drills and handheld power tools, the StepPower geometry reduces cutting resistance by up to 50% compared to standard drills. This efficiency allows for faster drilling progress while drastically extending battery runtime. Its unique tip design prevents "walking" on smooth or curved surfaces like pipes, ensuring instant centering without a center punch. From 4.0 mm diameters and above, the bit features a 3-flat shank for a positive mechanical lock, preventing any spinning in the chuck under high torque.

Constructed from high-grade HSS and enhanced with a wear-resistant TiN layer, the 9501 series excels in steel, cast iron, aluminum, and plastics. Whether you are performing precision installs or heavy-duty site work, the StepPower TiN provides a cooler-cutting, longer-lasting, and more precise drilling experience than traditional twist drills.

FEATURES:

• Titanium Nitride (TiN) Coating for increased surface hardness and significantly longer tool life
• Innovative Step Technology creates clean, circular holes with up to 8 steps depending on diameter
• Self-Centering Split Point ensures precise positioning and prevents "walking" on smooth surfaces
• 3-Flat Anti-Slip Shank (from Ø 4.0 mm) provides maximum torque transfer and prevents chuck damage
• Energy Efficient Design reduces cutting force, maximizing the battery life of cordless tools
• Superior Heat Resistance allowed by the TiN coating, enabling higher cutting speeds
• Burr-Free Results at the hole exit, eliminating the need for secondary deburring tasks
• Multi-Material Versatility highly effective in steel, non-ferrous metals, and reinforced plastics
• DIN 338 Standard dimensions for compatibility with standard jobber-length applications
• Optimized Chip Clearance via the stepped geometry which breaks material into manageable chips

Ideal for industrial professionals and tradespeople who require a high-speed, long-life drill bit that delivers industrial-grade precision with the portability of handheld tools.
