Value Collection 91040 Spotting Drill 0.5in 90deg Solid Carbide

Product Description

The VALUE COLLECTION 91040 is a solid carbide spotting drill designed to create accurate starter holes and seat countersinks before full drilling operations. With a 90-degree point angle and a 0.5-inch cutting diameter, this tool establishes precise hole locations on a variety of materials, reducing walk-off and improving positional accuracy in machining applications. The bright, uncoated carbide construction provides rigidity and thermal resistance suitable for general-purpose shop use. At 4 inches overall length, it fits standard drill chucks and CNC tool holders without excessive overhang, making it a dependable choice for machinists and toolroom technicians.

This spotting drill is suited for general-purpose use in machine shops, production environments, and maintenance facilities. It is intended for use in CNC machining centers, manual mills, and drill presses where accurate hole spotting is required before running twist drills, gun drills, or boring operations. The straight-cylindrical shank provides straightforward setup in standard collets or drill chucks. Its single-ended configuration and right-hand cut make it compatible with conventional spindle rotation.

Compatibility

Designed as a general-purpose spotting drill compatible with CNC machining centers, manual knee mills, and drill presses using standard 0.5-inch collets or drill chucks.

Installation Notes

Spotting drills are installed and removed by machinists or toolroom technicians. Always power down and lock out the spindle before changing tooling. Secure the straight-cylindrical shank fully within the collet or chuck to the recommended grip depth before running the spindle. Use appropriate feeds and speeds for the workpiece material per standard machining practice.
