Guhring 9055110115000 Carbide Drill Bit 0.4528 in

Product Description

The GUHRING 9055110115000 is a solid carbide jobber-length drill bit designed for precision drilling in ferrous materials. Built to DIN 6537L standards, it features a 140-degree split-point (SU) geometry with web thinning for self-centering entry, reducing the need for a center punch on flat or curved surfaces. The cutting flutes are finished with FIREX coating, a multilayer physical vapor deposition finish that extends tool life and resists heat buildup in demanding production environments. With a 5xD flute-to-diameter ratio and through-coolant capability, this bit is suited for CNC machining centers and deep-hole drilling applications where chip evacuation and thermal management are critical. Licensed machinists, tool-and-die shops, and production machine operators are the primary users.

This drill bit is built for cutting cast iron and steel workpieces in both job-shop and production settings. The straight-cylindrical shank seats directly into standard drill chucks and collet holders without modification. Its regular spiral flute geometry maintains consistent chip flow at moderate to high spindle speeds. Applications include through-hole and blind-hole drilling in structural steel, ductile iron, and gray cast iron components typical of manufacturing, fabrication, and maintenance machining operations.

Key Features

• FIREX multilayer coating for extended tool life in ferrous materials
• 140-degree SU split point with web thinning for self-centering, walk-free entry
• Through-coolant capable for deep-hole drilling and heat management
• Submicron solid carbide construction for rigidity and edge retention
• DIN 6535 and DIN 6537L compliant straight-cylindrical shank
• 2-flute regular spiral design optimized for cast iron and steel chip evacuation

Compatibility

Designed for use in CNC machining centers and drill presses with standard straight-shank collet or chuck toolholding rated for the 0.4724-inch shank diameter. Primary workpiece materials are cast iron (ISO material code K) and steel (ISO material code P) per the manufacturer specification.

Installation Notes

Installation and use of this tool should be performed by qualified machinists familiar with carbide tooling requirements. Ensure the machine spindle and toolholder are fully de-energized and locked out before inserting or removing the bit. Confirm the collet or chuck bore matches the 0.4724-inch shank diameter before tightening. When running through-coolant, verify that the coolant supply pressure and flow rate are appropriate for the application before initiating the cut.
