Guhring 9005150011000 Stub Drill Bit 0.0433in Pm

Product Description

The GUHRING 9005150011000 is a stub-length (screw machine length) twist drill bit designed for precision drilling in ferrous materials. Built from powdered metal (PM) with a coated finish, this bit delivers consistent cutting performance in cast iron and steel. The 130-degree split point with web thinning reduces thrust and improves centering without a pilot hole. At 0.0433 inches in diameter and 1.1024 inches overall length, it fits tight-clearance applications where standard jobber-length bits cannot be used. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup during extended drilling operations. Machinists, tool and die technicians, and maintenance mechanics are the primary users of this bit.

This drill bit is suited for production and maintenance drilling in cast iron and steel workpieces. The stub-length design provides added rigidity compared to jobber-length bits, making it appropriate for use in drill presses, CNC machining centers, and screw machines where short overhang is required. The straight cylindrical shank ensures compatibility with standard drill chucks and collet holders. The Series 515 designation follows DIN 1897 standards, common in precision metalworking and industrial maintenance environments where tight dimensional tolerances are required.

Key Features

• Powdered metal construction with coated finish for extended tool life in ferrous materials
• 130-degree standard point angle with web thinning reduces entry thrust and improves hole accuracy
• Parabolic flute geometry promotes chip evacuation in deep and interrupted cuts
• Stub length design adds rigidity and reduces deflection in tight setups
• Straight cylindrical shank fits standard drill chucks and collet systems
• Conforms to DIN 1897 specification for consistent dimensional standards

Compatibility

Designed as a DIN 1897 stub-length drill bit for use in cast iron and steel workpieces. Compatible with standard drill chucks and collet holders accepting a straight cylindrical shank in the applicable diameter range.

Installation Notes

This bit is installed and used by machinists, CNC operators, and maintenance technicians. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not have through-coolant capability. Follow shop safety protocols and machine guarding requirements when operating drilling equipment.
