Guhring 9005350047000 Taper Length Drill Bit Hss

Product Description

The GUHRING 9005350047000 is a taper length twist drill bit in the Series 535 line, manufactured from high-speed steel (HSS) with a bright, uncoated finish. It is sized to wire gauge No. 13, corresponding to a decimal diameter of 0.1850 inches. The 130-degree standard point angle and web-thinned, parabolic flute geometry promote aggressive chip evacuation and reduce thrust force during drilling. With a flute length of 3-7/32 inches and an overall length of 4-31/32 inches, this bit handles deeper hole applications where a jobber-length drill would fall short. It is intended for use by machinists, tool-and-die technicians, and maintenance professionals working in production or job-shop environments.

This drill bit is rated for use in aluminum alloy, cast iron, and steel. The straight cylindrical shank allows it to seat in standard drill chucks and collet-style toolholders without modification. The taper length format makes it well suited for drilling deeper holes in structural components, fixture plates, and machined assemblies where standard-length bits cannot reach. It conforms to DIN 340 specification, which governs taper length drill geometry, ensuring dimensional interchangeability with other DIN 340 compliant tooling. This bit is sold individually and must be ordered in multiples of 10.

Key Features

• Wire size No. 13, 0.1850 inches decimal diameter with diameter tolerance of +0.000 to -0.018 mm
• 130-degree standard point angle with web-thinned tip for reduced entry force
• Parabolic flute with parallel web configuration promotes efficient chip removal
• Taper length OAL of 4-31/32 inches for deeper reach than jobber-length equivalents
• Bright uncoated HSS construction — suitable for regrinding and general-purpose metal drilling
• Conforms to DIN 340 specification for dimensional consistency

Compatibility

Rated for drilling aluminum alloy, cast iron, and steel. Straight cylindrical shank is compatible with standard three-jaw drill chucks and ER-style collet holders sized for 0.1850-inch shank tooling.

Installation Notes

Installation and use of this tooling should be performed by qualified machinists or maintenance technicians familiar with drill press, milling machine, or lathe-mounted drilling operations. Secure the workpiece firmly before drilling and confirm the chuck or collet is torqued to the toolholder manufacturer's specification. Ensure spindle speed is appropriate for the material and diameter being drilled — excessive speed in cast iron or steel will shorten tool life. Inspect the cutting edges and web before each use; a chipped or worn point should be reground or the bit replaced before continuing production.
