Osg 63703 Spotting Drill 3mm 60deg Hss Tin Coated

Product Description

The OSG 63703 is a high-speed steel spotting drill designed to create precise, centered starter holes before through-drilling or reaming operations. With a 3 mm cutting diameter, a 60-degree point angle, and a titanium nitride (TiN) coating, this drill delivers accurate hole location and extended tool life in general-purpose machining environments. The spiral flute geometry and right-hand cut direction promote clean chip evacuation. Machinists and tool-and-die professionals use this drill when consistent hole positioning is critical before committing a larger drill to the workpiece. It is part of OSG Series 1200.

This spotting drill is suited for use on CNC machining centers, drill presses, and manual mills across light manufacturing, job shop, and production floor settings. The straight cylindrical shank provides reliable tool holding in standard collets and drill chucks. Its compact overall length of approximately 1.89 inches keeps the tool rigid during contact, minimizing walkout on flat or curved surfaces. It is sold as a single-ended tool, packaged individually.

Key Features

• 60-degree point angle for accurate spotting and center-starting before primary drilling
• TiN coating reduces friction and improves wear resistance for extended tool life
• High-speed steel construction handles a broad range of workpiece materials in general-purpose applications
• Spiral flute design with 20-degree helix angle supports efficient chip clearance
• Straight cylindrical shank fits standard collets and drill chucks without special toolholding
• Right-hand cut direction compatible with conventional spindle rotation

Compatibility

Designed as a general-purpose spotting drill for use in standard drill presses, CNC machining centers, and manual milling machines equipped with toolholding that accepts a 3 mm straight cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool from the chuck or collet. Verify the shank is fully seated and the toolholder is properly torqued or tightened before operation. Do not exceed the recommended speed and feed parameters for the workpiece material and tool diameter.
