Accupro A-6140125R Spotting Drill 1.25mm Solid Carbide

Product Description

The ACCUPRO A-6140125R is a solid carbide spotting drill designed to create accurate, centered starting points for follow-up drilling operations. With a 120-degree drill point angle and a cutting diameter of 1.25mm (0.0492 inches), this tool establishes precise cone seats that improve hole location and reduce drill walking. The overall length is 30mm (1.181 inches), and the 2-flute spiral geometry supports clean chip evacuation during short spotting passes. The bright, uncoated finish is suitable for general-purpose applications where a coating is not required. Installed by machinists and toolroom technicians, this drill is a standard component in precision hole preparation workflows.

This spotting drill is suited for general-purpose spotting operations on a wide range of workpiece materials. The 1.25mm cutting diameter targets small-bore applications common in instrument manufacturing, electronics, medical device, and precision mechanical work. The straight-cylindrical shank with a 1.50mm diameter (0.0591 inches) mounts directly into standard collet chucks and small-bore tool holders on CNC machining centers, drill presses, and manual mills. Single-ended design simplifies setup and tool changes.

Key Features

• 120-degree drill point angle for accurate center spotting and countersink seating
• Solid carbide construction for rigidity and wear resistance in precision applications
• 1.25mm cutting diameter with 4.20mm flute length for controlled spotting depth
• 2-flute spiral geometry promotes chip clearance in small-diameter spotting operations
• Bright, uncoated finish for general-purpose use across common workpiece materials
• Straight-cylindrical shank compatible with standard collet systems

Compatibility

Designed as a general-purpose spotting drill for use in standard collet chucks and small-bore tool holders accepting a 1.50mm straight-cylindrical shank.

Installation Notes

This tool is installed by machinists in CNC or manual machining environments. Secure the straight shank in a properly sized, clean collet or drill chuck before operation. Confirm spindle speed and feed rate are appropriate for the workpiece material and tool diameter before engaging the cut. Inspect the cutting edges for wear or chipping before each use, particularly in high-cycle production settings.
