Guhring 9055100125000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100125000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding production environments. Built to DIN 6537 K standards, this right-hand cut bit features a 140-degree split point (SU type) with web thinning that reduces entry thrust and improves centering. At 12.50 mm (0.4921 inches) in diameter, it runs a 2-flute regular spiral configuration with coolant-through capability, making it well suited for deep-hole drilling cycles where chip evacuation and heat management are critical. Machinists and tool-room technicians working in high-volume metal removal applications rely on submicron carbide grade tooling like this for consistent hole quality and extended tool life.

This drill bit is designed for use in CNC machining centers, screw machines, and production drilling operations targeting cast iron and steel workpieces. The screw machine length format provides a compact, rigid setup that minimizes deflection at higher feed rates. Coolant-through channels allow high-pressure coolant delivery directly to the cutting edge, supporting elevated spindle speeds and extended run times between tool changes. The straight-cylindrical shank seats securely in standard drill chucks and collet systems.

Key Features

• Solid submicron carbide construction for high-performance drilling in cast iron and steel
• 140-degree SU split point with web thinning reduces thrust and improves self-centering
• Coolant-through design supports high-pressure internal coolant delivery
• 2-flute regular spiral configuration promotes efficient chip evacuation
• Screw machine length (3xD flute-to-diameter ratio) for rigid, low-deflection setups
• Built to DIN 6537 K specification for consistent dimensional accuracy

Compatibility

Designed for use in CNC machining centers and screw machines with primary workpiece materials of cast iron and steel. Fits standard straight-cylindrical shank drill chucks and collet systems accepting a 14.00 mm shank diameter. Part of GUHRING Series 5510.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom personnel with the machine in a full stop and lockout-tagout procedures followed. Confirm the spindle bore and collet or chuck accepts the 14.00 mm straight shank before seating the tool. When using the coolant-through feature, verify that machine coolant pressure and flow rate are compatible with the tool before running production cycles. Do not exceed the drill point geometry recommendations for the workpiece material being cut.
