High hardness of drills, typically between HRA89-93, far exceeds that of other common metals, allowing them to maintain excellent shape and dimensional accuracy during stamping processes, and resist wear and deformation. How should drills be maintained and cared for?

Regular cleaning

Drills can accumulate oil, dust, and other impurities during use, which can affect their performance and lifespan. Therefore, regular cleaning is necessary to remove surface impurities. You can wipe the drill surface with a clean cloth or brush, or use a cleaning agent for a thorough wash. Be cautious to avoid scratching the drill surface with hard objects to prevent damage.

2. Inspect cutting edge

Regularly inspect the cutting edge of the drill bit for sharpness and signs of wear or chipping. If the cutting edge is found to be dull or shows wear or chipping, it should be promptly sharpened or replaced. When inspecting the cutting edge, use a magnifying glass or microscope for a more accurate assessment of its condition.

3. Storage Management

When not in use, drills should be stored properly to avoid impacts, compression, and corrosion. They can be placed in a dedicated tool box or case, and stored in a dry, well-ventilated area. During storage, care should be taken to prevent the drill from coming into contact with other metal items to avoid chemical reactions that may damage it.

4. Regular lubrication

For drills that require frequent disassembly and installation, regular lubrication can be applied to reduce friction between the drill and the mold, thereby extending their service life. Specialized lubricants or greases can be used for lubrication, applied to the surface and installation areas of the drill. During the lubrication process, it is important to avoid the lubricant entering the cutting edge of the drill to prevent affecting the quality of stamping.
