Guhring 9005350049800 Taper Length Drill Bit 0.1960 in

Product Description

The GUHRING 9005350049800 is a taper length twist drill bit designed for production and maintenance drilling in metal fabrication environments. Built to DIN 340 specification, this high-performance high speed steel (HSS) bit features a 130-degree split point and a parabolic flute geometry that improves chip evacuation and reduces heat buildup during extended cutting cycles. The cylindrical shank measures 0.1961 inches in diameter with a web-thinned, parallel web configuration for reduced thrust force at entry. It is sold individually and suits shops that need reliable, tight-tolerance hole quality in ferrous and non-ferrous metals.

This drill bit is rated for use in aluminum alloy, cast iron, and steel. The taper length body — overall length of 5-3/16 inches with a flute length of 3-7/16 inches — gives it reach beyond what a jobber-length bit provides, making it well suited for deep-hole drilling in flanges, structural members, brackets, and similar work. The 10xD flute-to-diameter ratio supports drilling to a maximum depth of 3.131 inches in a single pass under appropriate cutting conditions. It carries a bright uncoated finish, which is typical for HSS tooling used across a wide range of general metalworking applications.

Key Features

• DIN 340 taper length specification with 5-3/16 inch overall length for extended reach applications
• 130-degree standard point angle with web-thinned parallel web for reduced entry thrust
• Parabolic flute geometry promotes efficient chip clearance in deep-hole drilling
• High performance HSS construction rated for aluminum alloy, cast iron, and steel
• Right-hand cut, cylindrical shank — compatible with standard drill chucks and collet holders
• Bright uncoated finish; no coolant-through requirement for general metalworking use

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit for Series 535 tooling applications. Rated by the manufacturer for use in aluminum alloy, cast iron, and steel workpieces.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or toolroom technician. Secure the cylindrical shank fully in a properly sized drill chuck or collet before operation and confirm runout is within acceptable limits for the application. Always match spindle speed and feed rate to the workpiece material per standard HSS drilling guidelines. Inspect the cutting edges and web for wear before each use and replace the bit when dimensional tolerance or surface finish degrades.
