Precision Twist Drill 6000090 Spotting Drill 1/2 in Hss

Product Description

The PRECISION TWIST DRILL 6000090 is a high-speed steel spotting drill designed to create precise, accurately located starter holes before final drilling operations. Built to a 90-degree point angle, this tool establishes a clean center point that guides follow-up twist drills and reduces walking on flat or curved workpiece surfaces. The 0.5000-inch cutting diameter pairs with a straight cylindrical 0.5000-inch shank for secure chuck engagement. At 3.75 inches overall length with a 1.375-inch spiral flute, the 6000090 is sized for bench drill presses, CNC machining centers, and manual mill operations. Right-hand cutting geometry with a bright, uncoated finish suits general-purpose spotting across a wide range of base metals.

This spotting drill fits production and maintenance machining environments where hole location accuracy is critical. The SPS-90 series is suited for use on steel, aluminum, cast iron, and similar machinable materials in general-purpose shop settings. Typical applications include pre-spotting holes before twist drilling, countersinking pilot operations, and layout work on metal plate and structural shapes. Machinists, toolroom technicians, and maintenance tradespeople working in fabrication, HVAC equipment manufacturing, and mechanical shops will find this a standard go-to spotting tool.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the straight shank fully into a drill chuck or collet before operation and verify runout before beginning a cut. Power down and de-energize the machine spindle before changing or inspecting the tool. Follow the machine manufacturer's recommended speeds and feeds for the workpiece material and tool diameter.
