Accupro A-6140300R Spotting Drill 3mm 2-flute Solid Carbide

Product Description

The ACCUPRO A-6140300R is a solid carbide spotting drill designed to create precise starter holes for follow-on drilling operations. With a 120-degree drill point angle and a 3mm cutting diameter, this tool accurately locates and seats subsequent drill bits, reducing walking and improving hole position accuracy. The 2-flute spiral configuration supports clean chip evacuation in a wide range of workpiece materials. The bright, uncoated finish makes this tool well suited for general-purpose spotting applications. Machinists and tool-and-die technicians working in CNC and manual machining environments are the primary users of this drill.

This spotting drill is intended for general-purpose use across common shop materials including steel, aluminum, and non-ferrous alloys. The straight-cylindrical shank allows direct installation into standard drill chucks, collet holders, and tool holders sized for 3mm shanks. With an overall length of 38mm and a flute length of 7.5mm, this drill fits compact tooling setups and short-reach applications. It is a single-ended tool designed for single-use orientation without repositioning.

Key Features

• 120-degree drill point angle for accurate hole location and compatibility with standard drill bit geometry
• Solid carbide construction provides rigidity and wear resistance for consistent spotting performance
• 2-flute spiral design promotes chip evacuation during the spotting operation
• Bright, uncoated finish suitable for general-purpose spotting across a range of materials
• Straight-cylindrical shank for direct mounting in standard collets and drill chucks
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as a general-purpose spotting drill for use in CNC machining centers and manual drill presses equipped with tooling that accepts a 3mm straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists familiar with rotating-tool setup procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool from the holder. Seat the shank fully into the collet or chuck and verify runout with a dial indicator before beginning production. Do not exceed the tool manufacturer's recommended spindle speed range for the workpiece material and tool diameter.
