Accupro 89698641 Spotting Drill 90 Degree 1/4 Inch Carbide

Product Description

The ACCUPRO 89698641 is a 90-degree solid carbide spotting drill designed to create precise starter points for follow-on drilling operations. With a 0.25-inch cutting diameter and a 2-flute spiral flute design, it seats accurately and reduces walk before the primary drill engages. The bright, uncoated finish suits general-purpose spotting across a wide range of materials. At 2.5 inches overall length with a 0.75-inch flute length, this is a compact, rigid tool built for machine shop and production-drilling environments. Machinists and CNC operators are the primary users.

This spotting drill is suited for use in CNC machining centers, knee mills, and drill presses where consistent, repeatable spot-drilling is required before through-hole or blind-hole drilling. The 90-degree included angle is a common standard that matches a large portion of drill point geometries in general-purpose metalworking and fabrication applications. The straight cylindrical shank fits standard collets and drill chucks without modification.

Key Features

• 90-degree drill point angle for general-purpose spot drilling
• Solid carbide construction provides rigidity and wear resistance
• 2-flute spiral design for efficient chip clearance during spotting
• Bright/uncoated finish compatible with dry and light-coolant applications
• Right-hand cutting direction with a straight cylindrical shank
• Single-ended design with 0.75-inch flute length for compact reach

Compatibility

Designed as a general-purpose spotting drill compatible with standard collet systems and drill chucks accepting a 0.25-inch straight cylindrical shank.

Installation Notes

Installation is performed by machinists or CNC operators. Secure the shank fully in a collet or drill chuck before running the spindle, and verify runout is within acceptable tolerance for the application. Use appropriate speeds and feeds for carbide tooling in the workpiece material. Avoid impact or side-loading forces that can chip carbide at the cutting edge.
