Guhring 9005490039700 Jobber Drill 5/32 Inch Hss

Product Description

The GUHRING 9005490039700 is a 5/32 inch diameter jobber-length drill bit built for high-performance drilling in a range of materials. Manufactured from high speed steel with a bright, uncoated finish, it features a parabolic flute geometry that promotes efficient chip evacuation and reduces heat buildup during the cut. The 130-degree split point with web thinning allows the bit to start on contact without walking, reducing the need for a center punch on most setups. With a 2-flute design and straight-cylindrical shank, this bit is compatible with standard drill chucks and collet-style toolholders. It is built to DIN 338 specifications and carries a high-performance grade designation from GUHRING, making it a reliable choice for machinists and maintenance technicians working in production or job-shop environments.

This jobber drill is suited for drilling aluminum and a range of other workpiece materials where a parabolic flute geometry improves chip flow and reduces chip packing in deeper holes. The Series 549 designation places it in GUHRINGs high-performance jobber line. With an overall length of 2-15/16 inches and a flute length of 1-11/16 inches, it handles typical through-hole and blind-hole applications at depths up to approximately 1.459 inches. The straight-cylindrical shank diameter matches the drill diameter at 5/32 inch, allowing direct chucking in most standard drill presses, CNC machining centers, and hand drills used in trade and manufacturing settings.

Key Features

• Parabolic flute design promotes chip evacuation and reduces heat in aluminum and similar materials
• 130-degree split point with web thinning for self-starting, reduced thrust drilling
• High speed steel construction, bright/uncoated finish for versatile material compatibility
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Right-hand cutting direction, 2-flute configuration

Compatibility

Designed as an OEM-style jobber drill built to DIN 338 standards, suitable for use in standard drill chucks and collet toolholders that accept a 5/32 inch straight-cylindrical shank. Primary workpiece material classification includes aluminum and non-ferrous materials (material codes K, N, P).

Installation Notes

This drill bit is installed by machinists, tool and die technicians, and maintenance trades using drill presses, CNC machining centers, or hand-held power drills. Secure the shank fully in the chuck or collet and verify runout before operation. Always bring spindle speed to a full stop before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not support through-coolant delivery.
