Guhring 9005490097000 Jobber Drill Bit 9.7mm Hss

Product Description

The GUHRING 9005490097000 is a jobber length drill bit designed for professional metalworking and machining applications. Built from high speed steel with a bright uncoated finish, this bit features a parabolic flute geometry and a web-thinned, tapered web configuration that improves chip evacuation and reduces thrust when drilling. The 130-degree split point is optimized for clean entry on aluminum and other non-ferrous materials. At 9.7 mm in diameter and 5-15/64 inches overall length, this bit conforms to DIN 338 standards and is rated as a high performance grade tool suited for production-level use by machinists and tool and die professionals.

This drill bit is primarily intended for use in aluminum and similar non-ferrous and thermoplastic workpiece materials, making it a practical choice for aerospace, automotive, and general fabrication shops. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. The parabolic flute profile with a 5xD flute-to-diameter ratio supports deeper chip clearing relative to standard jobber geometry, reducing heat buildup during through-hole drilling operations on CNC machines, drill presses, and handheld power tools.

Key Features

• 9.7 mm diameter with a decimal inch equivalent of 0.3819 inches for precise sizing reference
• Parabolic flute design with web thinning improves chip flow and reduces cutting resistance
• 130-degree point angle optimized for aluminum and non-ferrous materials
• High speed steel construction with bright uncoated finish for general-purpose durability
• Straight-cylindrical shank fits standard chucks and collet systems without adapters
• Conforms to DIN 338 specification for consistent dimensional tolerancing

Compatibility

Designed as an OEM-spec replacement or new-installation drill bit for use in standard jobber-length drill applications on aluminum, non-ferrous metals, and plastic workpiece materials per DIN 338 Series 549 classification.

Installation Notes

This bit is installed by machinists and drill press operators using standard drill chucks or collet holders compatible with a 0.3819-inch straight-cylindrical shank. Ensure the workpiece is securely fixtured before drilling to prevent walkout. Use appropriate cutting fluid or coolant when drilling aluminum at production feed rates to preserve tool life, noting this bit does not include through-coolant capability. Inspect the cutting edges for wear before each use, as a dull point on a bright-finish HSS bit can cause work hardening in certain alloys.
