Osg HP245-2087 Solid Carbide Jobber Drill Bit 5.3 Mm

Product Description

The OSG HP245-2087 is a solid carbide jobber-length drill bit engineered for high-performance drilling in steel, alloy steel, and cast iron. It measures 5.3 mm in diameter with an overall length of 82 mm and a flute length of 44 mm. The 140-degree point angle and R-thinned web promote self-centering entry and reduce thrust force. WD1 coating extends tool life in abrasive ferrous materials. The straight-cylindrical shank measures 6 mm in diameter, fitting standard drill chucks and collet holders used by machinists and tool-and-die professionals.

This drill bit is suited for general-purpose and precision drilling operations in metalworking environments, including production shops, maintenance facilities, and machine shops. Rated tool applications include blind hole drilling, cross hole drilling, through drilling, and self-centering starts. The 5xD flute-to-diameter ratio and regular spiral geometry support consistent chip evacuation in short-to-medium depth holes. It is sold individually.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• WD1 coating for extended tool life in steel and cast iron applications
• 140-degree point angle with R-thinned web for self-centering and reduced thrust
• Right-hand cut with regular spiral flute for consistent chip flow
• Straight-cylindrical 6 mm shank compatible with standard chucks and collet holders
• Diameter tolerance of +0.004 to +0.016 mm for controlled hole sizing

Compatibility

Designed as a high-performance replacement or production drill in applications requiring 5.3 mm diameter holes in steel, alloy steel, and cast iron workpieces. Part of the OSG HP245 series covering the 5.00 mm to 6.00 mm diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with drill press, CNC, or manual milling equipment. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Power down the spindle completely before changing or inspecting tooling. Cutting parameters should be selected based on workpiece material hardness and machine rigidity — do not exceed the tool manufacturer's recommended feed and speed ranges for carbide tooling.
