Precision Twist Drill 6000081 Spotting Drill 5/8 in Hss

Product Description

The PRECISION TWIST DRILL 6000081 is a high speed steel spotting drill designed to accurately locate and start holes before finish drilling operations. Built to Series SPS-120 specifications, it features a 120-degree drill point angle and a 5/8-inch cutting diameter (0.6250 inches decimal). The bright, uncoated finish suits general-purpose metal cutting applications where coating is not required. With an overall length of 4.375 inches and a 1.625-inch flute length, this tool fits standard drill chucks and machining setups. Machinists, tool-and-die professionals, and maintenance technicians install this drill in CNC machining centers, drill presses, and manual lathes to create accurate, centered starting points for subsequent drilling or tapping operations.

This spotting drill is suited for general-purpose use in production and maintenance environments. The 5/8-inch straight cylindrical shank fits standard tool holders and drill chucks without modification. The two-flute spiral design promotes chip clearance during the brief contact time typical of a spotting operation. It is most commonly used on ferrous and non-ferrous metals in light to medium machining applications where consistent hole location is required prior to drilling, reaming, or tapping.

Key Features

• 120-degree drill point angle for accurate hole spotting and center location
• 5/8-inch cutting diameter (0.6250 inches) with matching straight cylindrical shank for direct chuck mounting
• High speed steel construction for durability across general-purpose metal cutting
• Bright, uncoated finish suitable for standard cutting fluids and dry cutting
• Two-flute spiral design promotes chip evacuation during spotting contact
• Single-ended design with 1.625-inch flute length and 4.375-inch overall length

Compatibility

Designed as a general-purpose spotting drill compatible with standard drill chucks and tool holders accepting a 5/8-inch straight cylindrical shank. Suitable for use on drill presses, CNC machining centers, and manual milling machines performing spotting operations on ferrous and non-ferrous metals.

Installation Notes

This tool is installed and operated by machinists, tool-and-die technicians, and maintenance professionals. Secure the straight cylindrical shank firmly in a drill chuck or collet holder before use, and verify runout is within acceptable limits for the application. Apply appropriate cutting fluid for the workpiece material unless performing dry cutting. Never exceed the recommended surface speed for high speed steel tooling in the material being machined.
