Guhring 9005490027000 Jobber Drill Bit 2.7mm Hss

Product Description

The GUHRING 9005490027000 is a jobber-length twist drill bit designed for accurate, repeatable hole-making in light-metal and non-ferrous applications. It measures 2.7 mm (0.1063 inches) in diameter with an overall length of 61.00 mm (approximately 2-13/32 inches) and a flute length of 33.00 mm. The bit is manufactured from high-speed steel with a bright, uncoated finish and features a parabolic flute geometry that promotes efficient chip evacuation. The 130-degree split point with web thinning reduces walking and entry force, making this bit well suited for production drilling and field service work performed by machinists, maintenance technicians, and mechanical contractors.

This drill bit is rated for primary use in aluminum, non-ferrous metals, and plastics, aligning with its DIN 338 Series 549 designation and high-performance grade classification. The parabolic flute profile with a 5xD flute-to-diameter ratio supports drilling to a maximum depth of 28.95 mm (1.14 inches) without coolant-through capability. Right-hand cutting direction and a straight-cylindrical shank sized at 0.1063 inches make it compatible with standard drill chucks and collet holders used in both bench-top drill presses and handheld power tools across light manufacturing, HVAC fabrication, and plumbing rough-in work.

Key Features

• 2.7 mm (0.1063 inches) diameter, DIN 338 Series 549 jobber-length geometry
• 130-degree drill point angle with web thinning reduces thrust force and prevents bit walk
• Parabolic flute design promotes chip clearing at depths up to 28.95 mm (1.14 inches)
• High-speed steel construction with bright, uncoated finish suitable for aluminum, non-ferrous metals, and plastics
• Straight-cylindrical shank fits standard drill chucks without adapters
• Tapered web configuration adds rigidity while maintaining cutting efficiency

Compatibility

Designed as an OEM-specification replacement or stock drill conforming to DIN 338 standards, this bit fits any standard drill chuck or collet holder accepting a 0.1063-inch straight-cylindrical shank. Primary workpiece material compatibility includes aluminum, non-ferrous metals, and plastics per the manufacturer-assigned material codes K, N, and P.

Installation Notes

Install the shank fully and evenly into a keyed or keyless chuck before tightening to prevent runout. Power down and de-energize any drill press or power tool before bit changes. Follow applicable shop-safety and OSHA general-industry standards when operating rotating cutting tools. Do not exceed the rated maximum drilling depth of 1.14 inches in a single pass without retracting to clear chips.
