Accupro A-6140270R Spotting Drill 2.7mm 120 Deg Carbide

Product Description

The ACCUPRO A-6140270R is a solid carbide spotting drill designed to create accurate center marks and pilot locations before drilling operations. With a 2.7 mm (0.1063 inch) cutting diameter and a 120-degree point angle, it produces consistent, repeatable spot locations that keep follow-on drills on target and reduce walking. The overall length is 38 mm (1.4961 inches), keeping the tool compact and rigid in the spindle. A spiral flute geometry and right-hand cutting direction promote smooth chip evacuation during the spot cycle. This tool is intended for use by machinists and CNC operators working in production or job-shop environments.

The A-6140270R is suited for general-purpose spotting applications across a range of workpiece materials where a bright, uncoated solid carbide tool is appropriate. The 3 mm (0.1181 inch) straight-cylindrical shank fits standard collets and drill chucks commonly found on machining centers, CNC lathes with live tooling, and bench drill presses. Single-ended construction keeps setup straightforward. It is appropriate for use in light-to-medium production runs where precise hole location is critical before reaming, tapping, or drilling to final diameter.

Key Features

• 120-degree point angle for accurate spot location and reduced thrust load on follow-on tools
• Solid carbide construction for rigidity and extended tool life compared to HSS alternatives
• 2.7 mm cutting diameter with 7.5 mm (0.2953 inch) flute length for shallow, controlled spotting
• Bright/uncoated finish suitable for a wide range of general-purpose materials
• Spiral two-flute design promotes chip clearance during the spot cycle
• Straight-cylindrical 3 mm shank for compatibility with standard collets and chucks

Compatibility

Designed as a general-purpose spotting drill for use in machining centers, CNC mills, and drill presses equipped with collets or drill chucks accepting a 3 mm straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully and evenly in the collet or chuck to the recommended grip depth before tightening to prevent runout. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting spindle speed and feed rate for the workpiece material.
