Guhring 9055100059500 Screw Machine Drill Bit 15/64

Product Description

The GUHRING 9055100059500 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding industrial applications. Built to DIN 6537K standards, this 15/64 inch (0.2344 inch) diameter bit features a 140-degree split point with SU geometry and web thinning for reduced thrust and self-centering entry. The straight-cylindrical shank measures 6.00 mm in diameter, and the overall length is 66.00 mm. Coolant-through capability makes it suitable for high-speed production environments where heat management is critical. Licensed machinists, tool-and-die workers, and CNC operators are the primary users of this tooling.

This drill bit is designed for cutting cast iron and steel in screw machine length applications, where a shorter flute-to-diameter ratio of 3xD keeps the tool rigid and reduces deflection. The regular spiral flute with parallel web configuration channels chips efficiently during through-hole and blind-hole operations. A maximum drilling depth of 25.00 mm suits typical production drilling cycles on CNC machining centers, drill presses, and screw machines running in right-hand rotation. The coated carbide substrate extends tool life in abrasive ferrous workpiece materials.

Key Features

• Solid submicron carbide construction for wear resistance in ferrous materials
• 140-degree SU point with web thinning reduces entry thrust and improves hole accuracy
• Coolant-through design supports high-speed and high-feed production drilling
• Screw machine length body (3xD flute ratio) maximizes rigidity and minimizes deflection
• Straight-cylindrical shank compatible with standard collet and drill chuck toolholding
• Conforms to DIN 6537K specification for consistent dimensional tolerancing

Compatibility

Designed as an OEM-style replacement and standard tooling option for right-hand rotation CNC machining centers, screw machines, and drill presses requiring a 15/64 inch diameter screw machine length carbide drill bit. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and tool changes must be performed with the machine powered down and the spindle fully stopped. Secure the straight-cylindrical shank in a properly sized collet or drill chuck to the toolholder manufacturer's specified clamping torque range. Verify coolant-through passages are clear before initiating a cutting cycle. Handling carbide tooling requires care to avoid chipping the cutting edges during setup.
