Micro 100 SPD-250-090 Spotting Drill 0.250 in 90 Deg Carbide

Product Description

The MICRO 100 SPD-250-090 is a solid carbide spotting drill designed to create precise starter locations for follow-up drilling operations. With a 90-degree point angle and a 0.250-inch cutting diameter, it establishes accurate, clean center spots that help prevent drill wander on subsequent operations. The 2-flute spiral flute geometry and bright/uncoated finish suit a wide range of general-purpose metalworking applications. At 2.5 inches overall length with a 0.75-inch flute length, this tool is well-proportioned for use in CNC machining centers, drill presses, and manual mills where precise hole location is critical.

This spotting drill is suited for general-purpose machining environments in both production and job-shop settings. It is typically used ahead of twist drills, taps, or reamers to establish a clean, accurately positioned entry point. The straight cylindrical shank at 0.250 inches fits standard collet chucks and drill chucks commonly found in light to medium-duty machine tool setups. Machinists, tool-and-die makers, and CNC operators working with steel, aluminum, and similar machinable materials will find this tool applicable to a broad range of workpiece materials.

Key Features

• 90-degree point angle for accurate hole spotting and drill alignment
• 0.250-inch cutting diameter with matching 0.250-inch straight cylindrical shank
• Solid carbide construction for rigidity and wear resistance
• 2-flute spiral geometry promotes chip clearance during spotting
• Bright/uncoated finish suitable for general-purpose applications
• Single-ended design for straightforward tool holding and setup

Compatibility

Designed as a general-purpose spotting drill for use in standard collet chucks and drill chucks accepting a 0.250-inch straight cylindrical shank, compatible with CNC machining centers, drill presses, and manual milling machines.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before mounting or changing tools. Secure the shank fully within the collet or chuck to the recommended grip depth before operation. Follow machine manufacturer guidelines and applicable shop safety standards when setting speeds and feeds for carbide tooling.
