Preventing corrosion in carbide drill bits
Corrosion can severely impact the performance and lifespan of carbide drill bits, making prevention a top priority in storage practices. To safeguard your valuable hard alloy scraper drill bit investments, consider the following strategies:
Control environmental factors
Maintain a stable, low-humidity environment to minimize moisture exposure. Use dehumidifiers or desiccants in storage areas to keep relative humidity below 50%. Ensure proper ventilation to prevent condensation, which can lead to oxidation and corrosion of the carbide material.
Protective coatings and packaging
Apply a thin layer of corrosion-inhibiting oil or specialized protective coating to the bit surface before storage. Use vapor corrosion inhibitor (VCI) packaging materials or bags to create a protective barrier against moisture and corrosive elements. These measures are particularly important for long-term storage or when transporting bits to different job sites.
Regular inspection and maintenance
Implement a routine inspection schedule to check for early signs of corrosion or damage. Clean bits thoroughly after each use, removing any debris or moisture that could contribute to corrosion. If corrosion is detected, address it promptly with appropriate cleaning and restoration techniques to prevent further damage.
Optimal humidity levels for bit storage
Maintaining the right humidity level is crucial for preserving the integrity of hard alloy scraper drill bits. Excessive moisture can lead to corrosion and deterioration of the bit's cutting edges, while extremely low humidity may cause brittleness in some materials. Here's how to achieve and maintain optimal humidity levels:
Ideal humidity range
Aim for a relative humidity (RH) between 30% and 50% in your storage area. This range helps prevent moisture accumulation without risking material desiccation. Use hygrometers to monitor humidity levels regularly, ensuring they remain within this optimal zone.
Humidity control methods
Employ dehumidifiers in storage areas to reduce excess moisture, especially in humid climates or during rainy seasons. In arid environments, consider using humidifiers to prevent the air from becoming too dry. Silica gel packets or other desiccants can be placed in storage containers to absorb excess moisture and maintain stable humidity levels.
Seasonal adjustments
Be prepared to adjust your humidity control measures based on seasonal changes. Increase dehumidification efforts during humid summer months and monitor closely during winter when indoor heating can create overly dry conditions. Regularly calibrate and maintain your humidity control equipment to ensure consistent performance year-round.
Should hard alloy bits be oiled before storage?
The question of whether to oil hard alloy scraper drill bits before storage is a common one among drilling professionals. While oiling can provide benefits, it's essential to understand the proper approach and potential implications:
Benefits of oiling
Applying a light coat of oil to hard alloy bits can create a protective barrier against moisture and atmospheric contaminants. This thin film helps prevent oxidation and corrosion, particularly important for long-term storage or in humid environments. Additionally, oiling can help maintain the bit's cutting edges, ensuring they remain sharp and ready for use.
Proper oiling techniques
When oiling hard alloy bits, use a specialized cutting tool oil or a light machine oil. Apply a thin, even layer using a clean cloth or brush, ensuring complete coverage of the bit's surface. Pay extra attention to cutting edges and threaded connections. Remove any excess oil to prevent dust accumulation and potential contamination of drilling fluids when the bit is next used.
Considerations and precautions
While oiling offers protective benefits, it's crucial to use the right type and amount of oil. Excessive oiling can attract dust and debris, potentially compromising the bit's performance. Some operators prefer to store bits dry, especially for short-term storage in controlled environments. If opting for dry storage, ensure bits are thoroughly cleaned and stored in a moisture-free area. Regardless of the chosen method, always clean and inspect bits before use to remove any storage oil or accumulated contaminants.
Conclusion
Proper storage of hard alloy scraper drill bits is essential for maintaining their performance and extending their operational life. By implementing these best practices for corrosion prevention, humidity control, and selective oiling, you can ensure your valuable drilling assets remain in optimal condition. Remember, the key to effective bit storage lies in creating a controlled environment that protects against moisture, corrosion, and physical damage.
