Osg 519015017 Spotting Drill 90 Deg 1/2 in Solid Carbide

Product Description

The OSG 519015017 is a 90-degree solid carbide spotting drill designed to create accurate, burr-free center points before drilling operations. Part of the OSG Series 5190, this two-flute tool features a spiral flute geometry with a 12-degree helix angle and an EgiAs surface finish that promotes chip evacuation and reduces built-up edge. The cutting diameter is 0.5 inches (1/2 inch), and the overall length measures 111 millimeters (4.37 inches). It is intended for use by machinists and tool-and-die professionals working on precision drilling setups in production or job-shop environments.

This spotting drill is suited for general-purpose spotting operations on a wide range of workpiece materials. The 90-degree point angle is compatible with standard drill point geometries, making it useful for starting holes that will be followed by twist drills, carbide drills, or boring operations. The straight cylindrical shank fits standard drill chucks and collet holders. Single-ended construction means the full tool length is available for rigid, concentric hole location on mills, machining centers, and drill presses.

Key Features

• 90-degree drill point angle for accurate hole location and compatibility with standard follow-on drills
• Solid carbide construction for rigidity and wear resistance in production environments
• EgiAs finish reduces friction and helps extend tool life in general-purpose applications
• Two-flute spiral design with 12-degree helix angle promotes chip flow and clean entry
• Straight cylindrical shank fits standard collets and drill chucks without adapters
• Single-ended tool provides maximum rigidity and concentricity during spotting operations

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and collet systems accepting a 0.5-inch straight cylindrical shank. Suitable for machining centers, CNC mills, and manual drill presses performing spot drilling operations.

Installation Notes

Spotting drills are installed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the chuck or collet holder. Confirm shank seating depth and runout before beginning a production run. Follow machine tool manufacturer guidelines for spindle speed and feed rate selection appropriate to the workpiece material.
