Guhring 9005490011900 3/64 Inch Hss Jobber Drill Bit

Product Description

The GUHRING 9005490011900 is a jobber length drill bit designed for precision drilling in a range of materials. Built from high speed steel with a bright uncoated finish, this bit features a parabolic flute geometry and a 130-degree point angle optimized for chip evacuation and reduced thrust. The straight-cylindrical shank measures 3/64 inch in diameter, matching the drill diameter for secure chuck engagement. Overall length is 1.5 inches with a flute length of 0.625 inches. Web thinning is applied at the tip to ease penetration, particularly in softer metals. This is a Series 549 tool rated as high performance grade per DIN 338 standards. It is suited for use by machinists, HVAC fabricators, electricians, and plumbers requiring accurate small-diameter hole placement.

This drill bit is rated for use in aluminum as its primary workpiece material, with material codes K, N, and P indicating suitability across non-ferrous metals and some plastics. The 5xD flute-to-diameter ratio supports deeper drilling relative to diameter, with a maximum drilling depth of 0.56 inches. Right-hand cut geometry is standard. The parabolic flute profile improves chip flow compared to standard twist geometry, reducing clogging in gummy materials like aluminum. This bit is sold individually per package with a minimum order quantity of 10 units.

Key Features

• High speed steel construction with bright uncoated finish for general-purpose durability
• 130-degree split point reduces walking and lowers required entry force
• Parabolic flute design improves chip evacuation in aluminum and non-ferrous metals
• Web-thinned tip with tapered web configuration for easier penetration
• DIN 338 standard compliance ensures dimensional consistency
• Right-hand cut, straight-cylindrical shank for compatibility with standard drill chucks

Compatibility

Designed as a DIN 338 jobber length drill bit for use in standard drill chucks and drill presses accepting a 3/64-inch straight-cylindrical shank, suitable for drilling aluminum, non-ferrous metals, and select plastics.

Installation Notes

This bit is installed and operated by machinists, fabricators, and trade professionals using handheld drills, drill presses, or CNC equipment. Secure the shank fully in the chuck before operation and verify chuck tightness. Coolant-through is not supported on this bit; use external cutting fluid when drilling in materials that generate heat or galling. Replace the bit at first sign of dulling to maintain hole diameter tolerance within the specified range of -0.014 to 0.000 mm.
