Guhring 9005490020800 Jobber Drill Bit Wire 45 Hss

Product Description

The GUHRING 9005490020800 is a high speed steel jobber-length drill bit sized to wire gauge No. 45, with a decimal diameter of 0.0820 inches. It features a 130-degree split point angle with web thinning for accurate self-starting and reduced thrust on entry. The parabolic flute geometry promotes efficient chip evacuation during deep hole drilling. The bright, uncoated finish suits general-purpose use across a range of workpiece materials. With an overall length of 1.9375 inches and a flute length of 0.9375 inches, this bit is built to DIN 338 standards and carries a heavy-duty grade rating. It is installed by machinists, tool-and-die technicians, and maintenance tradespeople working with precision drill presses and CNC equipment.

This drill bit is designed for drilling steel, cast iron, aluminum, and other non-ferrous metals in production and maintenance environments. The parabolic flute with a 5xD flute-to-diameter ratio makes it well suited for through-hole drilling at depths up to 0.8220 inches in these materials. The straight cylindrical shank with a diameter of 0.0819 inches fits standard Jacobs-style and precision keyless chucks. It is commonly used in light manufacturing, fabrication shops, and field maintenance applications requiring repeatable small-diameter hole geometry.

Key Features

• Wire gauge No. 45 size at 0.0820 inches decimal diameter for precise small-hole applications
• 130-degree point angle with web thinning reduces walking and entry thrust
• Parabolic flute design improves chip flow and reduces heat buildup
• High speed steel construction provides toughness across steel, cast iron, and non-ferrous workpieces
• Conforms to DIN 338 specification for consistent dimensional tolerancing
• Bright, uncoated finish compatible with cutting fluids and standard HSS service conditions

Compatibility

Designed as an OEM-style replacement or standard tooling selection for any drill press, CNC machining center, or hand drill with a chuck accepting a 0.0819-inch straight cylindrical shank, suitable for steel, cast iron, and non-ferrous material applications per DIN 338 Series 549 specifications.

Installation Notes

This bit is installed by machinists or maintenance technicians using a calibrated chuck with appropriate clamping pressure for the shank diameter. Ensure the spindle is fully stopped and locked before changing tooling. Use a cutting fluid or lubricant appropriate for the workpiece material to extend tool life and maintain hole tolerance. Follow applicable shop safety standards and machine manufacturer guidelines for small-diameter tooling speeds and feeds.
