Overview

Our Thread Button Drill Bits are precision-engineered for high-performance rock drilling across a wide range of applications. Manufactured from premium alloy steel and fitted with top-grade tungsten carbide inserts, these bits deliver exceptional durability, energy efficiency, and penetration rates—even in the most demanding drilling environments. With customizable designs and comprehensive thread options, we provide tailored solutions for soft, medium, and hard rock formations.

Customization – OEM & ODM Services

We offer full customization to meet your specific project requirements. Our engineering team can design and manufacture thread button bits based on your samples or technical drawings, including:

Bit diameter
Number and layout of air/water holes
Carbide button shape and configuration
Face shape design

Whether you are drilling in soft formations or hard, abrasive rock, we can tailor the bit geometry and material selection to maximize performance and service life.

Optimized Flushing System

Strategically positioned side and front flushing holes ensure superior air or water flow directly to the hole bottom. This design:

Quickly evacuates drill cuttings
Prevents bit balling (clogging)
Maintains high penetration rates in both dry and wet drilling conditions

This flushing efficiency is especially critical for deep blast holes in quarrying and open-pit mining operations.
