Guhring 9005490145000 Jobber Drill Bit 14.5mm Hss

Product Description

The GUHRING 9005490145000 is a jobber-length drill bit designed for high-performance drilling in a range of workpiece materials. 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 promotes efficient chip evacuation and reduces thrust during entry. The 130-degree point angle suits aluminum and a broad range of ferrous and non-ferrous materials. With an overall length of 6.6563 inches and a flute length of approximately 4.484 inches, this bit fits standard drill chucks and drill presses used in machine shop and maintenance environments.

This bit is suited for production drilling and maintenance applications in metalworking environments. The parabolic flute design at a 5xD flute-to-diameter ratio supports deeper hole drilling with reduced chip packing. Primary workpiece material classifications include aluminum, general non-ferrous metals, and steel (material codes K, N, and P). It conforms to DIN 338 standards, making it interchangeable with other DIN-spec jobber-length tooling in metric sizes. It is used by machinists, tool and die technicians, and maintenance trades working with ferrous and non-ferrous stock.

Key Features

• High speed steel construction with bright uncoated finish for general-purpose metalworking
• 130-degree split point angle reduces walking and suits aluminum and mixed-metal applications
• Parabolic flute geometry promotes fast chip evacuation and reduces heat buildup
• Web-thinned tapered web lowers thrust and improves hole entry performance
• Straight-cylindrical shank at 0.5709 inches diameter fits standard three-jaw chucks
• Conforms to DIN 338 specification for consistent dimensional interchangeability

Compatibility

Designed as an OEM-style jobber-length drill bit conforming to DIN 338, compatible with standard straight-shank drill chucks and drill presses accepting a 0.5709-inch shank diameter. Suitable for workpiece material codes K, N, and P as classified under DIN 338 Series 549.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with metal drilling operations. Secure the shank fully in the chuck before operation and verify chuck jaw engagement across the full shank contact length. Power down and de-energize the drill press or CNC spindle before bit changes. Do not exceed the recommended maximum drilling depth of 3.632 inches without retracting to clear chips.
