Guhring 9005010029500 Taper Length Drill Bit 0.1160 in

Product Description

The GUHRING 9005010029500 is a taper length twist drill bit designed for precise through-hole drilling in metalworking applications. Built from high speed steel (HSS) with a bright/uncoated finish, it features a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduces walking at entry. The 0.1160-inch (No. 32 wire gauge) diameter and 10xD flute-to-diameter ratio make it well suited for deeper hole applications where a jobber-length bit falls short. This is a general-purpose, right-hand-cut drill intended for use in manual or CNC drilling operations by machinists and maintenance technicians.

This bit is sized for work in aluminum alloy and steel across light manufacturing, maintenance, and fabrication environments. The cylindrical shank fits standard drill chucks without modification. The Series 501 designation follows DIN 340 specification, placing it in the taper length category with a flute length of approximately 2.594 inches and an overall length of approximately 3.9375 inches. It is sold individually and is appropriate for production drilling where chip clearance and hole quality are priorities over maximum tool life coating.

Key Features

• 130-degree point angle with web-thinned tip reduces entry force and minimizes walking on flat stock
• Parabolic flute with 10xD ratio supports deep-hole chip evacuation without pecking cycles in many applications
• High speed steel construction provides adequate toughness for aluminum alloy and steel drilling
• Bright/uncoated finish allows visual wear inspection during service life
• Parallel web configuration and DIN 340 standard geometry ensures consistent performance and replaceability
• Right-hand cut, cylindrical shank fits standard keyless and keyed drill chucks

Compatibility

Designed as a DIN 340 taper length drill bit with a cylindrical shank for use in standard drill chucks accepting a 0.1161-inch shank diameter. Rated for general-purpose drilling in aluminum alloy and steel per the manufacturer specification.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with metalworking practices. Secure the workpiece fully before drilling and confirm chuck runout is within acceptable limits for the diameter being used. Follow applicable shop safety standards including eye protection and chip guarding. Do not exceed the rated material applications stated by the manufacturer.
