Factory Resharpened Carbide Drills

These solid carbide micro drills have been professionally factory resharpened to provide accurate drilling performance at a lower cost than comparable new carbide drills. Because they are resharpened tools, minor cosmetic differences and slight flute-length variation may occur.

Use Notes

• Solid carbide drills are hard and accurate but also brittle.
• Use in a stable drill press, CNC machine, milling machine, PCB drill holder, or other controlled setup.
• Not recommended for handheld electric drills or unstable setups.
• Secure the workpiece and keep the drill properly aligned.
• Use proper feed pressure, spindle speed, and chip clearing for the material being drilled.

Suitable Materials

• PCBs and composites: Printed circuit boards, fiberglass, carbon fiber, and similar materials
• Plastics and acrylics: Engineering plastics, acrylic, and similar non-metallic materials
• Non-ferrous metals: Aluminum, brass, bronze, copper, and similar soft metals
• Wood and hobby materials: Hardwood, model-making materials, and detailed small-hole work

Colored depth-stop rings are included; ring color may vary from the photo.
