Accupro 89698633 Spotting Drill 90 Degree 3/16 Inch

Product Description

The ACCUPRO 89698633 is a solid carbide spotting drill designed to create precise, accurate starter holes for follow-on drilling operations. Built with a 90-degree drill point angle and a 3/16-inch cutting diameter, it establishes clean, centered entry points that reduce walking and improve hole location accuracy. The two-flute spiral design clears chips efficiently in general-purpose machining applications. With a 2-inch overall length and a bright, uncoated finish, this single-ended tool is suited for use in CNC machining centers, drill presses, and manual mills across production and job-shop environments. Machinists and tool-and-die professionals are the primary users.

This spotting drill is intended for general-purpose metal-cutting applications where accurate hole positioning is critical before reaming, tapping, or through-drilling. The straight cylindrical shank provides secure chuck or collet holding in standard toolholding systems. At 0.1875 inches in cutting diameter and 0.75 inches of flute length, it is sized for smaller-diameter work where precision spotting is required. It is well suited for production runs in steel, aluminum, and similar machinable materials where consistent center-point location is the priority.

Key Features

• 90-degree drill point angle for accurate spotting and center location
• Solid carbide construction provides rigidity and wear resistance over standard high-speed steel
• Two-flute spiral geometry promotes efficient chip evacuation
• Bright, uncoated finish compatible with a wide range of cutting fluids and materials
• Straight cylindrical shank fits standard chucks and collet systems
• Single-ended, right-hand cut configuration for conventional spindle use

Compatibility

Designed as a general-purpose spotting drill for use in CNC machining centers, drill presses, and milling machines that accept a straight cylindrical shank in 3/16-inch diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the drill from the chuck or collet. Confirm runout is within acceptable tolerance after seating the shank to maintain spotting accuracy. Use appropriate cutting fluid or coolant as recommended for the workpiece material to maximize tool life.
