Osg 8595462 Screw Machine Drill Bit 0.1819 in Hss

Product Description

The OSG 8595462 is a screw machine length drill bit designed for high-performance drilling in metalworking and fabrication applications. Built from high speed steel with a coated finish, this bit features a 120-degree faceted drill point and a web-thinned, tapered web configuration that reduces entry resistance and improves chip evacuation. The straight-cylindrical shank measures 6 millimeters in diameter, and the overall length is 68 millimeters (approximately 2.68 inches). With a 2-flute spiral design at a 5xD flute-to-diameter ratio, the 8595462 is suited for production drilling where consistency and tool life are priorities. It is sold individually.

This drill bit is engineered for drilling into steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length format — shorter overall length compared to jobber bits — provides added rigidity and is a standard choice in CNC machining centers, turret lathes, and drill press applications where stub-length tooling is specified. Wire size 14 (0.1819 inches, 4.62 mm) fits common tapping and clearance-hole requirements in precision metal fabrication and production shop environments.

Key Features

• High speed steel construction with coated finish for extended wear resistance
• 120-degree faceted drill point for clean entry on ferrous and non-ferrous metals
• Web-thinned, tapered web reduces thrust and improves chip flow
• Screw machine (stub) length adds rigidity over standard jobber-length bits
• Right-hand cut, 2-flute spiral design compatible with standard drill equipment
• Diameter tolerance of +0 to -0.018 mm for consistent hole sizing

Compatibility

Designed as a screw machine length replacement or production drill bit for use in applications requiring a wire size 14 or 0.1819-inch diameter hole in steel, stainless steel, aluminum, aluminum alloy, or aluminum silicate workpieces.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool-and-die professionals familiar with cutting tool setup and speeds-and-feeds selection. Secure the straight-cylindrical shank fully in the drill chuck or collet before operation, and verify chuck runout is within acceptable tolerance to protect the cutting edge. Disengage power and allow the spindle to come to a full stop before changing tooling. Follow the machine manufacturer and tool manufacturer guidelines for recommended speeds, feeds, and coolant use with high speed steel tooling.
