Guhring 9005490028700 No. 33 Hss Jobber Drill Bit

Product Description

The GUHRING 9005490028700 is a high-speed steel jobber-length drill bit in wire gauge size No. 33, measuring 0.113 inches in diameter. Built to DIN 338 standards, it features a 130-degree split point with web thinning for reduced thrust and cleaner entry. The parabolic flute geometry promotes efficient chip evacuation at higher feed rates. With a bright uncoated finish and straight cylindrical shank, this is a workhorse drill for production and maintenance work. Licensed machinists, tool and die technicians, and general metal fabricators reach for this bit when drilling through steel, cast iron, and non-ferrous materials in standard bench and CNC drilling operations.

This bit is sized for wire gauge No. 33 drilling in metals including steel, cast iron, aluminum, and other non-ferrous materials. The parabolic flute design and web-thinned point make it well suited for deeper hole applications where chip packing is a concern. The 5xD flute-to-diameter ratio gives adequate depth capacity for most through-hole and blind-hole setups on production floors and maintenance shops. It ships individually and is compatible with standard drill chucks accepting 0.113-inch straight shanks.

Key Features

• Wire gauge No. 33 diameter: 0.113 inches with tolerance of -0.014 to 0.000 mm for consistent hole sizing
• 130-degree split point with web thinning reduces walking and entry thrust on hard materials
• Parabolic flute geometry accelerates chip evacuation in deeper holes
• High-speed steel construction rated for steel, cast iron, aluminum, and non-ferrous workpieces
• Tapered web configuration adds rigidity and extends cutting edge life under heavy-duty use
• Conforms to DIN 338 specification for dimensional consistency

Compatibility

Designed as an OEM-specification replacement or production-use drill bit for applications requiring wire gauge No. 33 sizing in standard drill chucks with straight-shank collets or keyless chuck systems.

Installation Notes

Installation is performed by machinists, maintenance technicians, and metalworking professionals using standard bench drill presses, drill motors, or CNC machining centers. Secure the straight shank fully within the chuck before operation and verify chuck runout is within acceptable limits for the hole tolerance required. Always wear appropriate eye protection and secure the workpiece firmly before drilling. Follow applicable shop safety standards and equipment manufacturer guidelines for spindle speed and feed rate selection.
