Guhring 9055100095200 Screw Machine Drill Bit 0.375in

Product Description

The GUHRING 9055100095200 is a screw machine length solid carbide drill bit designed for high-performance drilling in demanding shop and production environments. Built to DIN 6537 K standards, it features a 0.375 inch (3/8 inch) diameter, a 140-degree split point (SU type), and a web-thinned, parallel web construction that reduces entry force and improves chip evacuation. The straight-cylindrical shank measures 10 millimeters in diameter. With coolant-through capability and a regular spiral flute design, this bit is suited for high-cycle CNC and screw machine applications where heat and chip management are critical. It is installed and run by machinists and tool-and-die professionals in production machining settings.

This drill bit is engineered for primary use in cast iron and steel workpieces. The screw machine length profile — shorter overall length for increased rigidity — makes it appropriate for tight-tolerance hole production in CNC machining centers, turret lathes, and screw machines. The 3xD flute-to-diameter ratio and coated submicron carbide grade support consistent performance in repetitive drilling cycles. The Series 5510 designation places this bit in a high-performance solid carbide product line built for precision metalworking applications.

Key Features

• Solid carbide construction with submicron carbide grade for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces thrust and improves self-centering
• Coolant-through design channels cutting fluid directly to the cutting edge for thermal control
• Screw machine length body provides added rigidity over jobber-length bits in high-cycle operations
• Regular spiral flute with parallel web promotes reliable chip evacuation in cast iron and steel
• Meets DIN 6537 K specification for consistent dimensional accuracy and interchangeability

Compatibility

Designed as an OEM-specification solid carbide screw machine drill for production metalworking in cast iron and steel. Primary workpiece materials listed by the manufacturer are cast iron and steel.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling requirements. Confirm spindle speed, feed rate, and coolant flow settings are appropriate for solid carbide before running. Carbide tooling is brittle — avoid side loading, interrupted cuts without verified parameters, or hand-feeding in rigid setups. Inspect the shank and collet or chuck bore for runout before mounting to protect the cutting edge and maintain hole tolerance.
