Guhring 9006520084300 Jobber Drill Bit Letter Q Hss Tin

Product Description

The GUHRING 9006520084300 is a jobber length drill bit sized to Letter Q (0.3319 inches) and manufactured from high speed steel with a titanium nitride (TiN) coating. It features a 130-degree split point, a parabolic flute geometry, and a web-thinned, tapered web configuration. The overall length is 4-19/32 inches with a flute length of 2-15/16 inches. Right-hand cut with a straight-cylindrical shank, this bit is engineered for high-performance drilling in production and maintenance environments. It is installed by machinists, tool-and-die professionals, and trade technicians requiring consistent hole quality in a standard jobber format.

This drill bit is rated for use in aluminum and non-ferrous materials, with primary workpiece material codes K, N, and P. The parabolic flute profile promotes efficient chip evacuation in these materials, reducing heat buildup and extending tool life. The 5xD flute-to-diameter ratio supports drilling depths up to 2.455 inches. It is suited to CNC machining centers, drill presses, and hand-held power tools where a straight-cylindrical shank is the standard interface. Individual packaging makes it appropriate for tool-crib stocking or single-replacement use.

Key Features

• Letter Q size at 0.3319 inches diameter with a diameter tolerance of -0.022 to 0.000 mm for precise hole sizing
• TiN coating over high speed steel substrate reduces friction and extends tool life in aluminum and non-ferrous applications
• 130-degree drill point angle with web thinning promotes self-centering and reduces thrust force at entry
• Parabolic flute geometry improves chip flow and reduces chip packing at deeper drilling depths
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Conforms to DIN 338 specification for jobber length geometry and tolerances

Compatibility

Designed as a DIN 338 jobber length replacement drill bit for use in standard drill chucks and collet holders accepting a 0.3319-inch straight-cylindrical shank. Primary workpiece material compatibility is rated for aluminum and non-ferrous materials per material codes K, N, and P as specified by the manufacturer.

Installation Notes

Installation is performed by machinists or qualified trade professionals. Ensure the drill press, CNC spindle, or hand-held drill is powered off and locked out before inserting or removing the bit from the chuck or collet. Confirm shank seating and chuck tightness before initiating a cut. Coolant-through is not supported on this bit, so external cutting fluid or misting should be used when drilling deeper holes to manage heat.
