Guhring 9055250095200 Extra Length Drill Bit 0.375in Carbide

Product Description

The GUHRING 9055250095200 is a solid carbide extra length drill bit engineered for demanding drilling applications in ferrous and non-ferrous materials. Measuring 0.375 inches in diameter with an overall length of approximately 6.38 inches (162 mm), this bit features a 140-degree split point and a FIREX coating finish that reduces friction and extends tool life under high-cycle production conditions. The straight-cylindrical shank diameter measures 0.3937 inches, making it compatible with standard chucks and collets. Built to DIN 6537 standards and classified as a high-performance grade tool, it is suited for use by machining professionals, tool-and-die shops, and maintenance technicians working with cast iron, steel, aluminum, and titanium alloy workpieces.

This Series 5525 drill bit is designed for deep-hole drilling with a flute-by-diameter ratio of 12xD, providing a maximum drilling depth of 4.162 inches (105.72 mm). The spiral flute design with a regular spiral type promotes consistent chip evacuation. Coolant-through capability supports high-feed-rate operations where heat buildup is a concern. Typical applications include facet point grinding setups and self-centering operations in production machining environments across both CNC and manual drilling equipment.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in hard materials
• FIREX coating finish reduces friction and improves tool life in ferrous and non-ferrous workpieces
• Coolant-through design supports high-feed-rate deep-hole drilling
• 140-degree standard point with web-thinned, tapered web for improved self-centering and reduced thrust
• 12xD flute-by-diameter ratio with a maximum drilling depth of 4.162 inches (105.72 mm)
• Built to DIN 6537 standard with right-hand cutting direction and two-flute spiral configuration

Compatibility

Designed for drilling cast iron and steel as primary workpiece materials (ISO material codes K and P), with secondary compatibility for aluminum and titanium alloys (ISO material codes H, M, N, and S). Suitable for use in standard chucks and collets accepting a 0.3937-inch straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool-and-die professionals familiar with carbide tooling. Ensure the machine spindle and workpiece are fully secured before initiating the drilling cycle. When using the coolant-through feature, verify that the coolant supply system is properly connected and pressurized per machine specifications. Carbide tooling is brittle and should not be subjected to lateral loading or interrupted cuts beyond the tool's rated application range.
