Accupro A-6140100R Spotting Drill 1mm 2-flute Solid Carbide

Product Description

The ACCUPRO A-6140100R is a solid carbide spotting drill designed to create precise starting points for subsequent drilling operations. With a 120-degree drill point angle and a 1mm cutting diameter, this tool produces accurate, centered spots that guide follow-up drills and reduce walkout on both ferrous and non-ferrous materials. The bright uncoated finish suits general-purpose applications where coating compatibility is a concern. At 30mm overall length with a 1.5mm straight cylindrical shank, it fits standard small-bore collet and drill chuck setups. Two spiral flutes with a right-hand cut provide clean chip evacuation in tight spotting passes. Machinists and CNC operators in production and job-shop environments are the primary users.

This spotting drill is suited for general-purpose machining applications where precise hole location is required before drilling, countersinking, or tapping. Its 3.4mm flute length and 1mm cutting diameter make it appropriate for small-feature work in metals, plastics, and composites. Typical use cases include CNC machining centers, manual mills, and drill press setups where starting-point accuracy directly affects finished-hole quality and positional tolerance.

Key Features

• 120-degree drill point angle for accurate spot placement compatible with standard twist drill geometries
• Solid carbide construction for rigidity and wear resistance in general-purpose machining
• Bright uncoated finish suitable for a wide range of workpiece materials without coating interaction concerns
• Two spiral flutes with right-hand cut for efficient chip clearance during spotting passes
• Straight cylindrical shank at 1.5mm diameter for use with standard collets and small-bore chucks
• Single-ended tool design for straightforward tool-path programming and setup

Compatibility

Designed as a general-purpose solid carbide spotting drill for use in standard collet systems and drill chucks accepting a 1.5mm straight cylindrical shank. No specific machine model or system compatibility was provided by the manufacturer for this part number.

Installation Notes

Spotting drills are installed and operated by machinists and CNC technicians. Ensure the machine spindle is fully stopped and the tool is seated squarely in the collet or chuck before tightening. Verify runout with an indicator before first use, as concentricity directly affects spot accuracy at this diameter scale. Follow shop-standard speeds and feeds for solid carbide at this diameter, and avoid side-loading the tool, which can cause breakage at small diameters.
