Guhring 9055140103200 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140103200 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding shop and field environments. Built to DIN 6537K standards, this bit features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank measures 12.00 millimeters in diameter, and the overall length is 102.00 millimeters with a flute length of 55.00 millimeters. The 2-flute regular spiral configuration with parallel web promotes efficient chip evacuation. This bit is installed and used by machinists, tool and die workers, and maintenance mechanics running screw machine or short-hole drilling operations.

The 9055140103200 is suited for drilling cast iron and steel in production and maintenance environments. The screw machine length profile makes it appropriate for drill press, CNC, and screw machine setups where a shorter, more rigid bit reduces deflection. The 3xD flute-to-diameter ratio supports drilling up to a maximum depth of 1.556 inches (39.52 millimeters). The coated submicron carbide construction holds up under the elevated heat and feed rates common in ferrous metal drilling applications.

Key Features

• Solid submicron carbide construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces entry thrust and walking
• DIN 6537K standard compliance for dimensional consistency
• Regular spiral, 2-flute design promotes chip clearance in cast iron and steel
• Straight-cylindrical shank for compatibility with standard collet and chuck systems
• High-performance series rated for production drilling at aggressive feed rates

Compatibility

Designed as an OEM-style replacement or direct-application screw machine drill bit for use in drill presses, CNC machining centers, and screw machines accepting a straight-cylindrical shank with a 12.00-millimeter shank diameter. Primary workpiece materials are cast iron and steel per manufacturer specification.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle and chuck or collet are fully powered down and locked out before changing tooling. Confirm shank seating depth and runout with a dial indicator before production use. Do not exceed the manufacturer-rated maximum drilling depth of 1.556 inches without retracting to clear chips.
