Guhring 9005350032500 Taper Length Drill Bit 0.1280 in

Product Description

The GUHRING 9005350032500 is a taper length twist drill bit designed for precision hole-making in metal fabrication and machining applications. It carries a 0.1280-inch (3.25 mm) diameter with a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduced cutting force. The overall length is 4.172 inches (106 mm) with a flute length of 2.719 inches (69 mm). Manufactured from high-speed steel with a bright/uncoated finish, this bit is intended for use by machinists, tool-and-die professionals, and industrial maintenance technicians who require consistent dimensional accuracy in production drilling operations.

This drill bit is suited for right-hand drilling in aluminum alloy, cast iron, and steel. The taper length format provides additional reach compared to a jobber-length bit, making it practical for deeper-hole applications in structural components and machined parts. It conforms to DIN 340 specification, which defines taper length drill geometry. The cylindrical shank fits standard drill chucks and collet holders. A maximum drilling depth of 2.525 inches (64.13 mm) makes it appropriate for through-hole and deep-hole work within its rated capacity.

Key Features

• Parabolic flute design promotes fast chip removal and lowers heat buildup during extended drilling cycles
• 130-degree point angle with web-thinned tip reduces thrust force and improves self-centering on entry
• High-speed steel construction provides toughness across aluminum alloy, cast iron, and steel workpieces
• DIN 340 taper length configuration extends reach beyond standard jobber drills without sacrificing rigidity
• Cylindrical shank with 0.1280-inch diameter fits directly into standard drill chucks and collet systems
• Bright/uncoated finish suits general-purpose metal drilling where coating adhesion is not a requirement

Compatibility

Rated for use in aluminum alloy, cast iron, and steel. Fits standard drill chucks and collet holders sized for a 0.1280-inch cylindrical shank. Conforms to DIN 340 taper length drill specification.

Installation Notes

Installation is performed by machinists and industrial maintenance technicians using standard drill press, milling machine, or hand-held power drill equipment. Ensure the spindle and workpiece are fully secured before engaging the cutting edge. Power down and de-energize all equipment before bit changes or chuck adjustments. Do not exceed the rated maximum drilling depth of 2.525 inches in a single pass without withdrawing to clear chips.
