Guhring 9012430055600 Jobber Drill Bit 7/32 in Carbide

Product Description

The GUHRING 9012430055600 is a jobber length drill bit engineered for high-performance drilling in demanding trade and industrial applications. Built from submicron-grade solid carbide and finished with a Titanium Nitride (TiN) coating, this bit delivers extended tool life and resistance to wear when cutting through cast iron and steel. The 140-degree split point (SU type) with web thinning promotes self-centering entry and reduces thrust force. The overall length is 81 mm with a 41 mm flute length, and the straight-cylindrical shank diameter matches the 7/32 inch drill diameter. This bit is sold individually and is suited for machinists, tool and die technicians, and maintenance mechanics working on precision metal fabrication.

This drill bit is designed for use in cast iron and steel workpieces, covering a drill size range of 0.2000 to 0.2500 decimal inch. The 5xD flute-to-diameter ratio supports drilling to a maximum depth of 1.29 inches (32.66 mm). Its regular spiral flute geometry and right-hand cutting direction make it compatible with standard drill presses, CNC machining centers, and hand-held power drills with appropriate chucks. The Series 1243 designation places it within a recognized GUHRING product family for solid carbide jobber bits.

Key Features

• Submicron-grade solid carbide construction for hardness and wear resistance in ferrous metals
• Titanium Nitride (TiN) coating reduces friction and extends cutting life
• 140-degree SU split point with web thinning enables self-centering without a center punch
• Right-hand cut, regular spiral flute geometry provides consistent chip evacuation
• Straight-cylindrical shank for secure seating in standard drill chucks and collets
• Diameter tolerance of 0.004 to 0.016 mm for precise hole sizing

Compatibility

Designed for drilling cast iron and steel workpieces. Compatible with standard drill chucks and collets sized for a 7/32 inch straight-cylindrical shank, including use in drill presses, CNC machining centers, and power hand drills. Primary workpiece material codes K and P apply.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety practices. Ensure the drill is fully secured in the chuck or collet and the workpiece is clamped before operation. Solid carbide tooling is brittle and should not be subjected to side loads or used in flex-shaft applications. Coolant-through is not supported on this bit; apply external cutting fluid appropriate for the workpiece material when drilling steel or cast iron.
