Guhring 9014520043000 Carbide Jobber Drill Bit No. 18

Product Description

The GUHRING 9014520043000 is a solid carbide jobber-length drill bit in wire size No. 18, measuring 0.1693 inches (4.30 mm) in diameter. Built to DIN 6539 standards, it features a 150-degree split point, a three-flute spiral configuration, and a web-thinned, tapered web design for self-centering entry without a center punch. The submicron carbide grade provides hardness and edge retention suited for drilling ferrous and non-ferrous metals, plastics, and composites. The bright uncoated finish leaves the carbide surface bare, making it a solid baseline for applications where a specific coating is not required. Machinists, toolroom technicians, and precision fabricators install this bit in CNC machining centers, drill presses, and handheld drilling fixtures.

This drill bit is designed for precision hole-making in production and toolroom environments where tight diameter tolerances are required. The 5xD flute-to-diameter ratio and a maximum drilling depth of 1.006 inches (25.55 mm) make it well-suited for through-hole and blind-hole work in medium-depth applications. The straight-cylindrical shank seats directly in standard drill chucks and collet holders without modification. Series 1452 from GUHRING is positioned for general-purpose and semi-precision drilling where carbide rigidity outperforms high-speed steel in harder or abrasive workpiece materials.

Key Features

• Solid submicron carbide construction for hardness and edge retention in demanding materials
• 150-degree standard point angle with web thinning for self-centering entry
• Three-flute spiral design improves chip evacuation compared to standard two-flute geometry
• Bright uncoated finish — no added coating layer to affect dimensional accuracy
• Straight-cylindrical shank compatible with standard chucks and collet systems
• Conforms to DIN 6539 specification for consistent dimensional and geometric standards

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for any machine tool accepting a straight-cylindrical shank drill in the No. 18 wire size (0.1693 inch / 4.30 mm) diameter range.

Installation Notes

Installation of this drill bit is performed by qualified machinists or toolroom technicians. Ensure the spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet holder. Verify chuck or collet bore matches the shank diameter of 0.1693 inches before seating. Follow the machine tool manufacturer recommended speeds and feeds for solid carbide tooling in the specific workpiece material being drilled.
