Guhring 9005490043700 Jobber Drill 11/64 in Hss 130 Deg

Product Description

The GUHRING 9005490043700 is an 11/64 inch (0.1719 inches) high speed steel jobber drill bit designed for general-purpose drilling in a wide range of materials. Built to DIN 338 standards, it features a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduces thrust force at entry. The straight cylindrical shank measures 0.1719 inches in diameter, and the overall length is 3-5/32 inches (3.1563 inches). The bright, uncoated finish is the factory standard for this heavy-duty HSS grade. Right-hand cutting direction. Licensed HVAC, plumbing, electrical, and mechanical contractors as well as machinists will find this drill appropriate for production and service work alike.

This Series 549 jobber drill is suited for drilling steel, cast iron, aluminum, and other non-ferrous materials in both shop and field applications. The parabolic flute design with a 5xD flute-to-diameter ratio and web-thinned, tapered web configuration makes it particularly effective when drilling deeper holes where chip packing is a concern. With a maximum drilling depth of 1.5930 inches (40.45 mm) and a flute length of 1-27/32 inches (1.8438 inches), it handles standard through-hole and blind-hole work in light structural and sheet metal components.

Key Features

• 130-degree split point reduces walking and lowers thrust force on entry
• Parabolic flute geometry with web thinning promotes fast chip evacuation
• High speed steel construction provides good toughness for a broad range of base materials
• DIN 338 standard ensures consistent dimensional tolerances and interchangeability
• Bright uncoated finish — no coating buildup to affect close-tolerance hole sizing
• Straight cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as an OEM-style jobber-length drill bit conforming to DIN 338, suitable for use in standard 3-jaw drill chucks, collet chuck systems, and CNC toolholders accepting a 11/64 inch straight shank. Rated for steel, cast iron, aluminum, and non-ferrous workpiece materials per manufacturer specifications.

Installation Notes

Install in a properly sized chuck or collet and confirm secure clamping before operation. Ensure the workpiece is firmly fixtured before drilling to prevent movement and bit breakage. Use appropriate cutting fluid or coolant when drilling ferrous materials to extend tool life, noting that this drill is not configured for through-spindle coolant delivery. Follow applicable shop safety practices and OSHA standards for rotating tool use.
