Accupro 89699078 Solid Carbide Spotting Drill 8mm 60 Deg

Product Description

The ACCUPRO 89699078 is a solid carbide spotting drill designed to create accurate starting points for subsequent drilling operations. With a 60-degree drill point angle and an 8mm cutting diameter (0.3150 inches), it establishes precise cone-shaped pilot spots that keep follow-up drills on center and reduce walking. The bright, uncoated finish suits general-purpose use across a wide range of workpiece materials. Overall length is 63mm (2.48 inches), with a 20mm (0.79 inch) spiral flute length. The straight-cylindrical shank measures 8mm (0.3150 inches) in diameter, compatible with standard collet chucks and drill chucks. This tool is installed and operated by machinists and toolroom personnel on CNC machining centers, drill presses, and manual mills.

This spotting drill is suited for general-purpose production and job-shop environments where accurate hole location is critical before drilling, reaming, or tapping. The single-ended, right-hand cut configuration is the standard setup for most vertical and horizontal machining center applications. Its 60-degree included angle matches common drill point geometries, helping to align the following drill accurately at the entry point. It is a practical choice for shops working in steel, aluminum, cast iron, brass, and similar machinable materials.

Key Features

• 60-degree drill point angle for accurate pilot spotting ahead of standard twist drills
• Solid carbide construction provides rigidity and wear resistance in general-purpose machining
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Spiral flute design with 2 flutes promotes chip clearance during spotting
• Straight-cylindrical shank fits standard collet chucks and drill chucks without special toolholders
• Right-hand cut, single-ended configuration for conventional CNC and manual machine setups

Compatibility

Designed as a general-purpose spotting drill for use with standard straight-shank collet chucks, ER collets, and drill chucks accepting an 8mm shank diameter on CNC machining centers, drill presses, and manual milling machines.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with cutting tool setup. Ensure the machine spindle is fully stopped and the machine is powered down or in a safe state before loading or removing the tool from the holder. Verify collet or chuck runout is within acceptable limits before use, as excessive runout will degrade spotting accuracy and reduce tool life. Follow the machine manufacturer and tooling manufacturer guidelines for appropriate feeds, speeds, and coolant application.
