Accupro A-6140080R Spotting Drill 0.8mm 120 Deg Solid Carbide

Product Description

The ACCUPRO A-6140080R is a solid carbide spotting drill designed to create accurate, centered starting points for follow-on drilling operations. With a 0.8 mm cutting diameter and a 120-degree point angle, it produces a precise cone seat that guides twist drills and reduces walking on flat or curved workpiece surfaces. The overall length is 30 mm (1.1811 inches), making it well suited for use in CNC machining centers and precision drill presses. The bright, uncoated finish is compatible with a wide range of materials and cutting fluids. Machinists and CNC operators in production and job-shop environments rely on this tool for consistent hole location accuracy.

This spotting drill is intended for general-purpose spotting and center-marking applications in metalworking. It performs in both low-volume prototype work and higher-volume production runs. The small diameter makes it particularly useful in micro-machining contexts, electronics component manufacturing, and precision instrument fabrication where tight positional tolerances are required. The right-hand cutting direction is standard for conventional CNC spindle rotation, and the straight cylindrical shank seats directly into collet chucks or drill chucks without adapters.

Key Features

• 0.8 mm cutting diameter for micro and precision spotting applications
• 120-degree point angle provides a stable seat for standard twist drill points
• Solid carbide construction delivers rigidity and wear resistance over high cycle counts
• Spiral flute, 2-flute design promotes chip evacuation during the spotting operation
• Bright, uncoated finish works across dry, mist, and flood coolant setups
• Straight cylindrical shank fits standard collet and drill chuck toolholding systems

Compatibility

Designed as a general-purpose spotting drill for use in CNC machining centers, drill presses, and precision fixtures accepting a 1.5 mm straight cylindrical shank. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

This tool is installed and changed by machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool from the toolholder. Confirm collet or chuck bore matches the 1.5 mm shank diameter to avoid runout and tool slippage. At this diameter, use low feed rates and verify spindle RPM against the carbide grade and workpiece material recommendations before initiating the cut.
