Guhring 9007300045700 Stub Drill Bit 0.18in Carbide 118deg

Product Description

The GUHRING 9007300045700 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in production and machining environments. Built to DIN 6539 standards, it features a 118-degree faceted point angle and a web-thinned tip geometry that reduces thrust and improves chip clearance at entry. The micrograin carbide construction delivers hardness and wear resistance suited for consistent hole quality at higher feed rates. At 0.18 inches (4.57 mm) in diameter, this bit covers wire gauge size 15 applications. It is intended for use by machinists and tool-and-die professionals requiring tight-tolerance drilling in general-purpose applications.

This drill bit is well suited for drilling aluminum and other non-ferrous or light-alloy workpieces in production shop environments. The stub-length format provides added rigidity compared to jobber-length bits, making it a reliable choice for CNC machining centers, drill presses, and screw machine operations where deflection control matters. The bright/uncoated finish is compatible with flood coolant or cutting oil use, though coolant-through capability is not supported on this model. The 3xD flute-to-diameter ratio supports chip evacuation in short-to-medium depth holes up to 0.675 inches.

Key Features

• Solid micrograin carbide construction for extended tool life in abrasive and non-ferrous materials
• 118-degree faceted point angle with web-thinned geometry reduces entry thrust and improves centering
• DIN 6539 standard, Series 730 — consistent dimensional conformance for tooling compatibility
• Stub length design increases rigidity and reduces deflection in short-hole drilling
• Bright/uncoated finish suitable for use with cutting fluids and oils
• Right-hand cut, 2-flute spiral configuration for standard CNC and manual drill applications

Compatibility

Designed as an OEM-style replacement or direct tooling selection for applications requiring a DIN 6539 stub-length carbide drill bit in the 0.15 to 0.20 inch diameter range, with a straight-cylindrical shank diameter of 4.57 mm.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists familiar with toolholder runout specifications and appropriate cutting parameters for carbide tooling. Ensure the drill press, CNC spindle, or screw machine chuck is clean and properly sized for a straight-cylindrical shank before seating the bit. Carbide tooling is brittle and should not be used in applications with significant vibration or interrupted cuts without verifying suitability. Always follow applicable shop safety procedures and machine manufacturer guidelines when setting feeds and speeds.
