Guhring 9012420035700 Screw Machine Drill Bit 0.1405 in

Product Description

The GUHRING 9012420035700 is a screw machine length solid carbide drill bit engineered for high-performance drilling in demanding production environments. Built to DIN 6539 standards, it features a 140-degree split point (SU point type) with web thinning for improved penetration and reduced thrust. The 0.1405-inch diameter corresponds to a 9/64-inch or Number 28 wire gauge size. The submicron carbide substrate and coated finish deliver extended tool life in abrasive materials. Right-hand cut with a regular spiral flute, this bit is the choice of machinists and maintenance technicians working with high-tolerance drilling applications.

This drill bit is suited for drilling cast iron and steel in screw machine, CNC, and general machining operations. The screw machine length designation means a shorter overall body for maximum rigidity in close-tolerance work. With a 3xD flute-to-diameter ratio and parallel web configuration, it maintains straightness in short-depth holes. Typical applications include production line drilling, fixture work, and precision component fabrication where hole location and diameter tolerance are critical.

Key Features

• Solid carbide submicron substrate with coated finish for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces entry thrust and improves hole accuracy
• Screw machine length body provides added rigidity over jobber-length bits
• Right-hand cut, 2-flute regular spiral design for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet systems
• Meets DIN 6539 specification for consistent dimensional and performance standards

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for screw machine and CNC drilling operations requiring a 0.1405-inch diameter hole in cast iron or steel workpieces.

Installation Notes

Installation and use of this drill bit is performed by machinists, toolroom technicians, or maintenance mechanics. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation. Ensure the spindle and workpiece are fully stopped before changing tooling. Do not exceed the recommended maximum drilling depth of 0.577 inches without retracting to clear chips.
