Guhring 9055100119100 Carbide Drill Bit 0.4688 in

Product Description

The GUHRING 9055100119100 is a solid carbide screw machine length drill bit designed for high-performance drilling in cast iron and steel. Part of the Series 5510 line and conforming to DIN 6537K, this bit features a 140-degree split point (SU type), two spiral flutes, and a web-thinned parallel web configuration for reduced entry force and improved chip evacuation. The straight-cylindrical shank measures 12.00 mm in diameter, and the overall length is 102.00 mm. Coolant-through capability supports high-speed production drilling where tool life and hole quality are critical. Licensed machinists, tool-and-die technicians, and industrial maintenance mechanics are the primary users.

This drill bit is suited for screw machine operations and short-hole drilling applications in ferrous materials, specifically cast iron and steel. The 3xD flute-to-diameter ratio and screw machine length body make it appropriate for CNC machining centers, turret lathes, and automatic screw machines where rigidity and repeatability matter. The coated carbide construction supports dry or through-coolant cutting cycles in production environments where cycle time and dimensional consistency are priorities.

Key Features

• Solid carbide construction rated for high-performance drilling in cast iron and steel
• 140-degree SU split point with web thinning for reduced thrust and accurate entry
• Coolant-through design supports high-speed and extended-run applications
• DIN 6537K compliant with straight-cylindrical shank for broad machine compatibility
• 3xD flute ratio in screw machine length format for rigidity in short-hole work
• Diameter tolerance held to +0.007 to +0.025 mm for consistent hole sizing

Compatibility

Designed as an OEM-style replacement or direct-application drill bit for use in CNC machining centers, turret lathes, and automatic screw machines accepting a straight-cylindrical shank; primary workpiece materials are cast iron and steel as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with carbide tooling handling. Secure the straight-cylindrical shank in a precision collet or drill chuck to the machine manufacturer's specified clamping torque range. Confirm coolant-through passages are clear before beginning a cutting cycle. Carbide tooling is brittle — avoid side loading, interrupted cuts without proper feed compensation, or dropping the bit on hard surfaces.
