Guhring 9005490017000 Jobber Drill Bit 51 Hss 130 Deg

Product Description

The GUHRING 9005490017000 is a jobber-length drill bit in wire gauge size 51, with a decimal diameter of 0.0669 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, it features a parabolic flute design that efficiently evacuates chips during drilling. The 130-degree point angle is optimized for fast, accurate entry into aluminum and other non-ferrous or soft materials. With a right-hand cut, web-thinned standard point, and straight-cylindrical shank, this bit is suited for precision drilling operations in production or maintenance environments. It conforms to DIN 338 standards and carries a high-performance grade designation. Installation is handled by machinists, tool-and-die techs, and HVAC or plumbing tradespeople requiring small-diameter hole work.

This drill bit is designed for use in aluminum, non-ferrous metals, and thermoplastic materials, consistent with its primary workpiece material codes K, N, and P. It is well-suited for light-production drilling, fixture work, and field service tasks requiring consistent small-bore holes. The 5xD flute-to-diameter ratio supports drilling depths up to 0.687 inches, making it appropriate for through-hole and shallow blind-hole applications in thin-wall or plate stock. It fits standard drill chucks accepting a 0.0669-inch straight shank. Sold individually; minimum order quantity is 10 units.

Key Features

• Wire size 51 with a decimal diameter of 0.0669 inches for precise small-bore drilling
• 130-degree point angle for reduced thrust and clean entry in aluminum and soft materials
• Parabolic flute geometry promotes efficient chip evacuation and reduces heat buildup
• Web-thinned, tapered-web construction lowers cutting resistance at the point
• Conforms to DIN 338 standard for consistent dimensional tolerances
• High-speed steel construction with bright, uncoated finish for general-purpose service life

Compatibility

Designed as an OEM-compatible replacement or standard jobber-length drill bit for use with any drill chuck or drilling machine accepting a 0.0669-inch straight-cylindrical shank. Primary workpiece material compatibility includes aluminum (K), non-ferrous metals (N), and thermoplastics (P) per material code classification.

Installation Notes

This drill bit is installed by machinists, maintenance technicians, and trade professionals using benchtop drill presses, hand drills, or CNC equipment with compatible chuck sizes. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant when drilling production quantities, even though the bit does not support through-coolant. Inspect the cutting edges for wear regularly, as small-diameter HSS bits are sensitive to overheating and side-loading.
