Accupro 89699086 Spotting Drill 8mm 90 Degree Solid Carbide

Product Description

The ACCUPRO 89699086 is a solid carbide spotting drill designed to create accurate starter holes for subsequent drilling operations. With an 8 mm cutting diameter and a 90-degree point angle, it precisely locates hole centers and helps guide twist drills, reducing walkout and improving positional accuracy. The bright uncoated finish suits a wide range of workpiece materials used in general-purpose machining. At 63 mm overall length and a straight-cylindrical shank, it seats securely in standard drill chucks and collet holders. Two spiral flutes clear chips efficiently over the 20 mm flute length. This tool is intended for use by machinists and CNC operators in production and job-shop environments.

The 89699086 is suited for general-purpose spotting and center-locating work on ferrous and non-ferrous materials in both manual and CNC drilling setups. The 90-degree point angle matches the most common spot-drilling convention, producing a chamfer that guides standard jobber-length and stub-length drills. Its compact overall length helps maintain rigidity and reduces deflection when used in vertical machining centers, knee mills, or drill presses. Single-ended construction makes tool changes straightforward.

Key Features

• Solid carbide construction for rigidity and wear resistance in general-purpose spotting applications
• 90-degree point angle for accurate hole location and drill-guiding chamfers
• 8 mm cutting diameter with matching 8 mm straight-cylindrical shank for direct chuck or collet mounting
• Two spiral flutes over 20 mm flute length for efficient chip evacuation
• Bright uncoated finish compatible with a broad range of workpiece materials
• Right-hand cut, single-ended design for standard spindle operation

Compatibility

Designed as a general-purpose spotting drill compatible with standard drill chucks and collet holders accepting an 8 mm straight-cylindrical shank, suitable for use on CNC machining centers, knee mills, and drill presses.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before loading or changing the tool. Secure the shank firmly in a collet or drill chuck rated for the intended spindle speed and confirm runout is within acceptable limits before cutting. Follow machine manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
