Micro 100 SPD-375-100 Spotting Drill 3/8 in Solid Carbide

Product Description

The MICRO 100 SPD-375-100 is a solid carbide spotting drill designed to create precise starter locations for follow-on drilling operations. With a 100-degree point angle and a 0.375-inch cutting diameter, it produces accurate, centered spots that reduce walking and improve hole-location repeatability on a wide range of workpiece materials. The bright, uncoated finish suits general-purpose applications across ferrous and non-ferrous materials. Overall length is 2.5 inches with a 1-inch flute length. Right-hand cut geometry and a straight cylindrical shank make this drill compatible with standard toolholders and chucks. Machinists and tool-and-die professionals will find this part a reliable everyday spotting solution.

This spotting drill is suited for use on CNC machining centers, drill presses, and manual mills in both production and job-shop environments. The 100-degree included angle matches the geometry of many standard twist drills, helping seat the follow-on drill accurately before full-depth cutting begins. It is well-suited for general-purpose spotting on steel, aluminum, brass, and similar materials where a two-flute spiral design provides adequate chip clearance and stable entry.

Key Features

• 100-degree drill point angle for accurate spotting and reduced drill walk
• Solid carbide construction for rigidity and wear resistance
• Bright, uncoated finish suitable for general-purpose machining applications
• Two-flute spiral design promotes chip evacuation during spotting operations
• Straight cylindrical shank fits standard chucks and toolholders
• Right-hand cutting direction compatible with conventional spindle rotation

Compatibility

Designed as a general-purpose spotting drill for use with standard straight-shank chucks and toolholders in CNC and manual machining setups.

Installation Notes

This tool is installed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is secure in the holder before beginning any setup. Verify that runout is within acceptable limits before use, as excessive runout will reduce spotting accuracy. Follow shop-standard speeds and feeds for carbide spotting drills in the workpiece material being machined.
