Gühring 9503 HSCO Spiralbohrer StepPower Drills Set (Made in Germany)

HIGHLIGHTS:

The Gühring StepPower HSCO-TiN Twist Drill (9503) is the pinnacle of handheld drilling technology, combining a 5% Cobalt-alloyed body with a premium Titanium Nitride (TiN) coating. This "best-of-both-worlds" construction provides extreme red-hardness for drilling tough alloys and a high-lubricity surface to prevent heat build-up. Featuring the patented multi-step tip geometry, this drill operates as its own pilot bit, ensuring perfectly concentric, burr-free holes in the most challenging materials, including Stainless Steel (Inox) and high-tensile steels.

Engineered to maximize the performance of cordless drills and portable power tools, the StepPower geometry significantly reduces axial force and cutting resistance. This results in faster penetration speeds and drastically extended battery life per charge. The self-centering tip allows for immediate starts on curved or polished surfaces without "walking" or the need for center punching. For diameters 4.0 mm and above, the 3-flat shank provides a secure mechanical lock in the chuck, eliminating slippage and ensuring maximum torque transfer during heavy-duty applications.

Constructed for the highest industrial standards, the 9503 series offers the longest tool life in the Gühring manual drilling range. It is the ultimate solution for professionals requiring industrial-grade precision in stainless steel, acid-resistant steel, and hard castings, while maintaining the flexibility of handheld operation.

FEATURES:

• HSCO Cobalt Base provides exceptional heat resistance for drilling hard and abrasive materials
• TiN Coating increases surface hardness and reduces friction for significantly longer tool life
• Innovative Step Technology eliminates the need for pilot drilling, creating clean holes in one pass
• Self-Centering Split Point ensures 100% accurate positioning on rounded or smooth surfaces
• 3-Flat Anti-Slip Shank (from Ø 4.0 mm) prevents chuck damage and ensures reliable torque transfer
• Energy Efficient Geometry reduces physical effort and extends cordless tool battery runtime
• Burr-Free Exit ensures high-quality finishes without the need for additional deburring tools
• Heavy-Duty Versatility optimized for Stainless Steel (Inox), high-alloy steels, and non-ferrous metals
• DIN 338 Standard dimensions for universal compatibility in all standard drill chucks
• Advanced Chip Breaking via the stepped cutting edges, preventing long, dangerous swarf

Ideal for maintenance and industrial professionals who require the maximum possible performance and longevity when drilling tough metals with portable equipment.
