How to properly store and maintain drill bits?
Cleaning: After use, remove debris and dust from the drill bit using a cloth or brush.
Rust prevention: Apply a small amount of lightweight machine oil to the drill bit surface to protect against rust, especially in humid environments.
Organized storage: Use drill bit index boxes or magnetic strip holders for categorized storage, preventing drill bits from colliding and damaging their cutting edges.
Do you have a pre-shipment inspection procedure?
Yes, we always test the product before delivery.
Can I take a sample for testing?
Yes, samples can be sent for testing before placing a bulk order.
When is the delivery time?
Stock orders are fulfilled within 7–15 days; for OEM and ODM orders, the exact timeline depends on the specific situation.
What are the payment terms?
Wire transfer or letter of credit, Western Union, Alipay, and more.
Why does the drill bit slip and fail to grip metal or smooth surfaces?
You can use a center punch to create a small indentation at the drilling location, providing the drill bit with a starting point. For surfaces that are particularly smooth, you can also apply tape over them before marking, which helps increase friction.
