Micro 100 SPD-500-140 Spotting Drill 140 Degree 0.5 Inch

Product Description

The MICRO 100 SPD-500-140 is a solid carbide spotting drill designed to accurately locate and start holes before finish drilling operations. With a 140-degree point angle and a 0.5000-inch cutting diameter, it creates a precisely positioned divot that guides twist drills and reduces walking on flat or angled surfaces. The spiral flute geometry and 25-degree helix angle promote clean chip evacuation during the spotting pass. At 2.5 inches overall length and weighing 0.3 pounds, this tool is suited for use in CNC machining centers and manual drill press setups where positional accuracy is critical. Machinists and tool-and-die professionals are the primary users of this type of tooling.

This spotting drill is used in general-purpose metal cutting applications where a consistent, burr-free starting point is required before drilling, countersinking, or tapping. The 140-degree point angle matches common jobber drill geometry, minimizing any secondary step in the operation sequence. Its straight cylindrical shank fits standard collet chucks and Weldon-style holders commonly found in production and job-shop environments. Single-ended construction keeps the tool compact and easy to set in tool length offset workflows.

Key Features

• Solid carbide construction provides rigidity and wear resistance for consistent spot geometry
• 140-degree drill point angle matches standard jobber drill point geometry for minimal transition step
• Spiral flute design with 25-degree helix angle promotes chip evacuation during spotting
• Two-flute configuration balances cutting forces for accurate center location
• Straight cylindrical shank fits standard collet and chuck toolholders
• Right-hand cutting direction compatible with conventional CNC and manual spindle rotation

Compatibility

Designed as a general-purpose spotting drill for use in standard straight-shank collet chucks, drill chucks, and hydraulic toolholders accepting a 0.5000-inch shank diameter across CNC machining centers and manual drilling equipment.

Installation Notes

Installation and use of this tooling should be performed by qualified machinists familiar with cutting tool setup and machine operation. Always power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or chuck is tightened to the toolholder manufacturer's specified procedure before operation. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speeds and feed rates appropriate to the workpiece material.
