Accupro 89698914 Spotting Drill 5/16 in 60 Deg Solid Carbide

Product Description

The ACCUPRO 89698914 is a solid carbide spotting drill designed to create accurate center points and chamfers before full-depth drilling operations. With a 60-degree point angle and a 0.3125-inch (5/16 inch) cutting diameter, it produces a precise conical seat that guides twist drills and reduces walkout on flat or angled surfaces. The bright/uncoated finish suits general-purpose work across a range of workpiece materials. At 2.5 inches overall length with a 1-inch flute length and a straight cylindrical shank, it fits standard drill chucks and collet holders used in CNC machining centers, manual mills, and drill presses.

This spotting drill is suited for general-purpose machining applications in job shops, production facilities, and maintenance departments. It is used to establish a precise starting point before drilling, countersinking, or tapping operations. The single-ended, right-hand cutting design is standard for use in rotating spindle setups. Machinists and CNC operators working with metals, plastics, and composite materials will find this tool appropriate for everyday hole-prep work where consistent entry angle and location accuracy are required.

Key Features

• 60-degree point angle for accurate spotting and chamfer creation prior to drilling
• Solid carbide construction provides rigidity and wear resistance compared to high-speed steel
• Bright/uncoated finish suitable for general-purpose cutting applications
• Spiral flute geometry with 2 flutes for chip clearance during spotting operations
• Straight cylindrical shank for compatibility with standard drill chucks and ER collets
• Right-hand cut, single-ended design for use in standard rotating spindle setups

Compatibility

Designed as a general-purpose spotting drill for use in CNC machining centers, manual mills, and drill presses equipped with standard straight-shank toolholders or collet systems accepting a 5/16-inch shank diameter.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or CNC operators familiar with rotating cutting tool setups. Ensure the machine spindle is fully stopped and the tool is securely seated in the holder before beginning any operation. Verify that runout is within acceptable limits after tool installation to maintain spotting accuracy. Follow applicable shop safety practices and machine manufacturer guidelines when selecting speeds and feeds.
