Accupro 89698666 Spotting Drill 1/2 in 90 Deg Solid Carbide

Product Description

The ACCUPRO 89698666 is a solid carbide spotting drill designed to create precise starter holes for follow-on drilling operations. With a 0.5 inch cutting diameter and a 90-degree point angle, it accurately locates drill starts and reduces walking on flat or curved workpiece surfaces. The 3 inch overall length and 1.25 inch spiral flute length make it suited for standard machining center and drill press setups. The bright, uncoated finish and straight-cylindrical shank allow direct installation into standard collets or drill chucks. This is a single-ended, two-flute tool intended for general-purpose spotting applications in a machine shop environment.

This spotting drill is used in general-purpose machining on mills, machining centers, and drill presses. It is suited for production and job-shop environments where accurate hole location is required before drilling, countersinking, or boring. The right-hand cut, straight shank, and 90-degree included angle make it a standard choice for operators working with steel, aluminum, cast iron, and similar materials. Machinists and CNC operators typically select this tool when pre-spotting to improve positional accuracy and extend the life of subsequent twist drills.

Key Features

• Solid carbide construction for rigidity and wear resistance in general-purpose spotting
• 90-degree point angle for accurate centering and compatibility with standard drill point geometry
• 0.5 inch cutting diameter with matching 0.5 inch straight-cylindrical shank for direct chuck or collet mounting
• Two spiral flutes promote chip clearance during spotting operations
• Bright, uncoated finish suitable for use with cutting fluids across a range of workpiece materials
• Single-ended, right-hand cut design for conventional spindle rotation

Compatibility

Designed as an OEM-style general-purpose spotting drill compatible with standard 0.5 inch collets, drill chucks, and tool holders used on CNC machining centers, knee mills, and drill presses.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is securely seated in a clean, properly sized collet or chuck before tightening. Verify runout with a dial indicator when positional accuracy is critical. Follow shop safety procedures and machine manufacturer guidelines for speeds and feeds when setting up this tool.
