Guhring 9055110047600 Carbide Jobber Drill Bit 3/16 in

Product Description

The GUHRING 9055110047600 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built to DIN 6537 L standards, it features a 3/16 inch (0.1875 inch) diameter, a 140-degree split-point (SU) tip, and a FIREX coating for extended tool life in abrasive materials. The straight-cylindrical shank and web-thinned, tapered web geometry reduce entry force and improve chip evacuation. With coolant-through capability and a 5xD flute-to-diameter ratio, this bit is engineered for precision and productivity in production environments. Licensed machinists and toolroom technicians are the primary users.

This bit is suited for drilling cast iron and steel in both CNC machining centers and manual drilling operations. The self-centering SU point eliminates the need for a center punch in many setups, making it well-suited for close-tolerance work. The regular spiral flute pattern and right-hand cut are standard for most vertical and horizontal drilling configurations. It is appropriate for both job-shop and production-line use where consistent hole quality is required across multiple workpiece materials.

Key Features

• 140-degree SU self-centering split point reduces walkout and eliminates pre-drilling in most setups
• FIREX coating provides heat and wear resistance for extended service life in ferrous materials
• Coolant-through design supports high-speed drilling with through-spindle coolant systems
• Solid submicron carbide construction maintains edge integrity in cast iron and steel
• Web-thinned, tapered web reduces thrust load and improves chip flow
• Conforms to DIN 6535 and DIN 6537 L standards for consistent dimensional accuracy

Compatibility

Designed for use in drilling cast iron and steel workpieces. Straight-cylindrical shank is compatible with standard drill chucks and collet holders sized for 0.2362 inch shank diameter. Suitable for CNC machining centers equipped with through-spindle coolant.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state per OSHA lockout/tagout procedures. Secure the shank fully within the chuck or collet to the recommended engagement depth before tightening. Verify coolant-through passages are clear and coolant pressure is set per machine specifications before initiating a drilling cycle. Do not use this bit in hand-held drilling applications; it is intended for machine-tool use only.
