Micro 100 QSPD-250-140 Spotting Drill 0.25in 140pt Carbide

Product Description

The MICRO 100 QSPD-250-140 is a solid carbide spotting drill designed to accurately locate and start holes before drilling operations. Featuring a 140-degree point angle and a 0.25-inch cutting diameter, it produces precise, centered starter spots that reduce walking and improve positional accuracy on the final drill. The tool is web-thinned for reduced thrust and cleaner entry, and it runs right-hand cut with a spiral two-flute geometry. With an overall length of 2.5 inches and a 0.75-inch flute length, it is sized for compact, controlled applications in CNC machining centers and manual mill setups alike.

This spotting drill is suited for precision machining environments where hole location accuracy is critical. The bright uncoated finish makes it appropriate for use in a wide range of base materials where coating buildup or reactivity is a concern. The MICRO 100 QSPD series with its Micro-Quik shank is commonly used in production shops, tool-and-die operations, and general machining applications where repeatable spotting is required before standard twist or carbide drill operations.

Key Features

• 140-degree point angle for accurate hole spotting and reduced drill wander
• Solid carbide construction for rigidity and wear resistance in demanding machining cycles
• Web-thinned geometry reduces cutting thrust and promotes clean entry
• Two spiral flutes with right-hand cutting direction for efficient chip movement
• Bright uncoated finish compatible with a broad range of workpiece materials
• Micro-Quik shank design for quick-change tooling compatibility

Compatibility

Designed for use in toolholders and quick-change systems compatible with the MICRO 100 QSPD series Micro-Quik shank profile. Verify shank interface compatibility with your toolholder before installation.

Installation Notes

Installation is performed by machinists and CNC setup technicians. Ensure the machine spindle is fully stopped and the tool is secured with proper torque to the toolholder manufacturer specifications before operation. Confirm runout with an indicator after installation to maintain spotting accuracy. Do not use this tool as a reamer or center drill substitute.
