Accupro 89698948 Solid Carbide Spotting Drill 7/8 in

Product Description

The ACCUPRO 89698948 is a solid carbide spotting drill designed to create accurate pilot indentations before full drilling operations. Built with a 60-degree drill point angle and a 7/8 inch (0.8750 inch) cutting diameter, this tool establishes precise center points that guide subsequent drill bits and reduce walk on flat and angled workpiece surfaces. The overall length is 4 inches with a 1-3/4 inch spiral flute length. It features a straight cylindrical shank at 7/8 inch diameter and a bright, uncoated finish. Right-hand cutting direction. Intended for machinists, tool-and-die professionals, and CNC operators working in general-purpose production environments.

This spotting drill is suited for general-purpose spotting applications in machine shops and fabrication environments. The single-ended design and straight shank make it compatible with standard drill chucks, collet holders, and toolholders used in CNC machining centers, drill presses, and manual mills. It is appropriate for use in metalworking operations where accurate hole placement is critical prior to twist drilling, reaming, or boring. The two-flute spiral configuration aids chip evacuation during the spotting pass.

Key Features

• 60-degree drill point angle for accurate pilot spotting and reduced drill walk
• Solid carbide construction for rigidity and wear resistance in general-purpose metalworking
• Bright uncoated finish — no coating buildup to affect dimensional tolerances
• Two-flute spiral design promotes chip clearance during spotting cycle
• Straight cylindrical shank fits standard chucks and collet systems
• Single-ended tool — consistent geometry from end to end

Compatibility

Designed as a general-purpose spotting drill for use in CNC machining centers, drill presses, and milling machines equipped with standard drill chucks or collet holders accepting a 7/8 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after tool installation to confirm concentricity before beginning a spotting cycle. Follow the machine manufacturer guidelines and applicable shop safety standards when securing tooling and setting feed and speed parameters.
