Product Specifications
PDC coreless drill bit is an efficient drilling tool that uses diamond composite (PDC) as the main cutting element and is widely used in the drilling field.
Working principle: PDC coreless drill bits break rock layers through scraping and shearing principles, without retaining rock cores during drilling, thereby reducing drilling resistance and improving drilling speed.
Structural features: Drill bits are usually designed with optimized chip removal grooves and coolant channels, which can effectively remove rock debris, reduce drill bit temperature, extend service life, and improve drilling efficiency.
Specification and model: PDC coreless drill bits come in various specifications, with common diameter ranges including Φ 59mm, Φ 75mm, Φ 94mm, Φ 113mm, and Φ 152mm, which can be selected according to different drilling needs.
Application areas: Mainly used for drilling gas drainage holes, discharge water holes, grouting holes, etc., it is also widely used in oil and gas drilling, geothermal development, water well drilling, engineering geological exploration and other fields, and can adapt to various geological conditions.
Performance advantage
High drilling efficiency: With a large amount of diamond exposed, the drill bit can always remain sharp and the drilling speed is fast.
Long life of drill bit: The cutting teeth are mainly composed of composite pieces, and its service life is more than 10 times that of hard alloy and 4-5 times that of ordinary diamond drill bits.
Low pressure and low-speed drilling: The drilling pressure is only about one-third of that of the same diameter diamond impregnated drill bit, which can reduce equipment load.
Good diameter retention effect: The composite drill bit can be embedded with diamond polycrystalline diameter retention inside and outside, with strong wear resistance, which can efficiently utilize the cutting teeth.

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 prevent rusting, especially in humid environments. Organized Storage: Store drill bits neatly by category using a drill bit index box or magnetic strip holder, ensuring they don’t collide with each other and risk damaging the 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 will be 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.
