Guhring 9050200016000 Single-flute Carbide Drill Bit

Product Description

The GUHRING 9050200016000 is a straight single-flute drill bit designed for precise, controlled drilling in demanding applications. Built from solid carbide in an uncoated finish, this bit delivers the hardness and rigidity required for clean hole production in materials that challenge conventional high-speed steel tooling. The single-flute geometry supports efficient chip evacuation in confined cutting zones, making it well-suited for small-diameter work where chip packing is a common failure point. With an 80 mm flute length and 125 mm overall length, the bit provides reach and stability for deep-hole applications while maintaining dimensional accuracy within h5 tolerance on the 1.6 mm diameter.

This drill bit is used in precision machining environments where tight tolerances and clean bore walls are required. Typical applications include circuit board drilling, small-diameter hole production in hard or abrasive materials, and any operation where a standard two-flute geometry would generate excessive heat or chip congestion. It is appropriate for use in CNC machining centers, drill presses, and precision manual spindles equipped to handle small-diameter carbide tooling. The Series 5020 designation places it within a recognized GUHRING product family for solid carbide single-flute drills.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• Single-flute geometry promotes efficient chip evacuation in small-diameter holes
• 1.6 mm diameter held to h5 tolerance for repeatable, accurate bore sizing
• Uncoated finish suitable for applications where coating is not required or preferred
• 80 mm flute length supports deep-hole reach relative to diameter
• 125 mm overall length provides shank engagement depth for secure tool holding

Compatibility

Designed as an OEM-style replacement or direct-specification drill bit for precision machining setups requiring a 1.6 mm solid carbide single-flute drill within the GUHRING Series 5020 product line.

Installation Notes

Installation of small-diameter carbide drill bits should be performed by a qualified machinist or tooling technician. Ensure the spindle and collet or chuck are clean and properly sized for the shank diameter before seating the bit to avoid runout. Carbide is brittle relative to high-speed steel — avoid side loading or impact during handling and setup. Confirm spindle speed and feed rate settings are appropriate for the material and diameter before initiating the cut.
