Frequently Asked Questions

What materials are used in these tapered bits?

Our tapered bits are manufactured using high-grade Alloy Steel Bar 45CrNiMoV combined with premium Tungsten Carbide Tips (YK05 or T6) for maximum durability and drilling efficiency.

Which taper angles do you offer?

We provide a comprehensive range of tapered connections including 6, 7, 11, and 12 degrees to ensure compatibility with various drilling equipment and rock conditions.

What is the difference between short and long skirt bits?

Short skirt bits are generally used in very hard rock formations where maximum energy transfer is needed, while long skirt bits provide better hole straightness and are ideal for medium to hard ground.

Can I choose different button configurations?

Yes, we offer various button quantities (6, 7, 8, or 9 pcs) and shapes, such as semi-ballistic, to match the specific requirements of your drilling project.

How are the products protected during shipping?

All drilling tools are carefully packed in sturdy wooden cases to prevent any damage to the carbide tips or the bit body during international transit.

What surface treatments are applied to the tools?

Our bits undergo a professional spray-paint finish (available in red, black, yellow, or white) which provides a protective layer against corrosion and helps in easy identification.
