Guhring 9006590019300 Screw Machine Drill Bit 0.076in Cobalt

Product Description

The GUHRING 9006590019300 is a stub-length screw machine drill bit engineered for demanding drilling applications in hard and abrasive materials. Built to DIN 1897 standards, this heavy-duty bit measures 0.076 inches (Wire Size 48) in diameter with an overall length of 1.4961 inches. The cobalt construction provides elevated heat resistance, making it well suited for cutting titanium alloys and other high-strength workpiece materials. A 130-degree split point and parabolic flute geometry promote fast chip evacuation and self-centering entry. Licensed HVAC techs, machinists, and industrial tradespeople reach for bits in this class when standard HSS tooling falls short.

This bit is designed for screw machine and stub-length drilling operations where reduced overhang improves rigidity and hole accuracy. The straight-cylindrical shank fits standard drill chucks without adapters. Primary workpiece material per specification is titanium alloy, though the cobalt grade handles stainless steel, hardened alloys, and other tough materials encountered in production machining and field service environments. The 2-flute parabolic design and web-thinned parallel web reduce thrust load and keep the bit tracking straight in short, precise holes.

Key Features

• Cobalt construction for heat resistance in hard and abrasive materials including titanium alloy
• 130-degree drill point angle with standard point type for self-centering entry
• Parabolic 2-flute design with web thinning for reduced thrust and improved chip evacuation
• Stub length per DIN 1897 for maximum rigidity in screw machine and short-hole applications
• Straight-cylindrical shank fits standard drill chucks directly
• Heavy-duty grade with diameter tolerance of +0.000 to -0.014 mm for consistent hole sizing

Compatibility

Designed as an OEM-style replacement or direct application bit for use in standard drill chucks and screw machine setups requiring a Wire Size 48 (0.076-inch) stub-length drill conforming to DIN 1897.

Installation Notes

Installation of small-diameter drill bits should be performed by qualified machinists or tradespeople familiar with rotating cutting tools. Secure the straight-cylindrical shank fully in a properly sized drill chuck before operation, and verify spindle runout is within acceptable limits to avoid premature breakage at this diameter. Disengage the machine and allow the spindle to come to a full stop before changing bits. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when drilling titanium alloy or hardened materials.
