Guhring 9055110119100 Carbide Jobber Drill Bit 15/32 in

Product Description

The GUHRING 9055110119100 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and hard materials. It carries a FIREX coating that extends tool life in abrasive applications and features a 140-degree split point (SU geometry) for self-centering entry without a center punch. The 2-flute spiral design with a web-thinned, tapered web core reduces thrust requirements and improves chip evacuation. Overall length is 4.65 inches with a flute length of 2.80 inches and a maximum drilling depth of 2.09 inches. Built to DIN 6537L standards using submicron carbide grade, this bit is appropriate for production and precision drilling environments.

This drill bit is intended for professional machining applications where tool life and hole accuracy matter. Primary workpiece materials are cast iron and steel. The straight-cylindrical shank and 0.4724-inch shank diameter allow direct chuck mounting in standard drill chucks, machining centers, and CNC drill presses. The coolant-through design supports internal coolant delivery when used in compatible spindle setups, making it suitable for deeper holes or higher feed rates in production environments. The 5xD flute-to-diameter ratio (Series 5511) positions this bit in GUHRING's line for general-purpose to demanding ferrous drilling work.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in steel and cast iron
• FIREX coating provides thermal and abrasion resistance in demanding cutting conditions
• 140-degree SU split point is self-centering, eliminating the need for a center punch
• Coolant-through design compatible with internal coolant delivery spindles
• Web-thinned tapered web reduces axial thrust and improves chip flow
• Meets DIN 6535 and DIN 6537L standards for consistent dimensional accuracy

Compatibility

Designed for use in steel (material code P) and cast iron (material code K) workpieces. Compatible with standard straight-cylindrical shank tool holders, drill chucks, and CNC machining center spindles that accept a 0.4724-inch shank diameter. Coolant-through capability requires a spindle with internal coolant delivery.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling professional. Secure the shank fully in a compatible chuck or tool holder before operation and verify runout is within acceptable tolerance for the application. Power down and de-energize the machine spindle before changing tooling. Do not exceed the recommended maximum drilling depth of 2.09 inches without retracting to clear chips.
