Celebrating China’s National Day 2026
Chenghui Wishes Our Customers and Partners a Happy National Day
As China celebrates National Day in October 2026, all of us at Chenghui would like to send our warm greetings to customers, partners and friends around the world.
National Day is a good time to celebrate progress, look back at the road behind us, and look forward to the chances ahead.
However, for Chenghui it is also a good time to think about something that has not changed through our growth. That is our promise to make reliable drilling tools and to support customers in real drilling projects worldwide.
Quick summary: This National Day, we thank every customer and partner for their trust. In short, our focus stays the same — reliable tools, steady quality, practical customization and long-term teamwork around the world.
A Moment to Celebrate Progress
Over the years, China’s manufacturing industry has kept growing in technology, output and global teamwork. For drilling tool makers like Chenghui, this progress shows up in two ways. First, better machines and methods. Second, the rising hopes of customers worldwide.
Today, drilling customers expect more than a standard product. For example:
- Reliable product quality
- Steady batch consistency
- Accurate sizes
- Good drilling-tool selection
- Custom solutions
- Clear technical talks
- Reliable delivery
Because of this, every customer need is a chance for us to improve our products and our production skill.
From China to Drilling Sites Around the World
Drilling conditions differ in every market. For example, a PDC bit used for a water-well job in Africa may need a different cutting structure from a bit used for geological exploration in Russia.
In the same way, a tricone bit used in Middle East limestone may face different conditions from a tool used in Southeast Asia. Because of this, our work does not stop at making a bit.
Before we suggest or make a product, we try to understand:
- Hole diameter
- Formation
- Drilling use
- Drilling depth
- Thread connection
- Drilling rig
- Current bit performance
In short, the more we understand the real job, the better we can match the tool to the customer’s needs.
Our Main Drilling Tool Solutions
Chenghui supplies a wide range of drilling tools for global projects. Our main product groups are listed below.
PDC Drill Bits

- Steel-tooth tricone bits
- Roller cutter solutions
Different IADC structures and connections can be chosen based on drilling needs.
Diamond Core Drilling Tools
- Impregnated diamond core bits
- Electroplated diamond bits
- PDC core bits
- Reaming shells
- Wireline core drilling tools
Common core drilling systems include:
AQ · BQ · NQ · HQ · PQ · NTW · HTW
DTH Drilling Tools
- DTH hammers
- DTH drill bits
- DTH accessories
These products are widely used in hard-rock drilling, water wells, mining and construction.
Customization Is an Important Part of Our Work
Standard products cannot solve every drilling problem. Different customers may need different diameters, cutter layouts, blade counts, thread connections, waterway shapes, gauge protection and body designs.
Because of this, we support custom drilling-tool production based on drawings, samples and project needs. Customers can send us:
- Technical drawings
- Product photos
- Existing drill bits
- Used-bit photos
- Formation info
- Required sizes
Our goal is not just to copy the look of a tool. Instead, whenever possible, we want to understand how the product will really be used.
Quality Is Built Into the Process
A reliable drilling tool depends on more than final inspection. In fact, quality starts much earlier.
For PDC tools, key production stages may include:
Design → Material Prep → Machining → Cutter Installation → Wear Protection → Size Check → Final QC
Each step can affect field performance. For example:
- Accurate cutter position can improve load spread
- Reliable brazing can cut early cutter loss
- Correct waterway design can improve cuttings flow
- Accurate threads can ensure a solid drill-string joint
- Gauge protection can help keep borehole size
Therefore, we believe production quality should focus on two things: product accuracy and batch consistency.
Every Repeat Order Means More Than a Number
For a drilling-tool maker, repeat orders matter a lot. A first order may come from product info, a talk or a customer tip.
However, a repeat order usually means something more. The tool has already been tested in the field. It has entered the borehole, faced the real rock, and the customer has decided to use it again.
Because of this, we value long-term teamwork more than one-time deals. On top of that, each customer’s drilling feedback helps us see how different structures work under different conditions.
Thank You to Our Customers Around the World
During this National Day, we would like to give special thanks to the customers and partners who have backed Chenghui.
Some began with a small trial order. Others reached out with just a photo of a drill bit. A few sent drawings. Many shared worn-bit photos after drilling. On top of that, some have kept working with us across many projects.
In short, every talk and every field result adds to our growth. Therefore, we truly value the trust behind every order.
Our Commitment Continues During the Holiday
According to China’s official 2026 public holiday plan, National Day is observed from October 1 to October 7, 2026.
During this period, reply times from some teams may be a little different from normal work days. However, global customers are still welcome to send us:
| Item | Example |
|---|---|
| Product questions | PDC bits, tricone bits, core bits, DTH tools |
| Technical drawings | Custom sizes, cutter layout, thread spec |
| Required sizes | Diameter, core diameter, connection |
| Formation info | Rock type, hardness, abrasiveness |
| Purchase needs | Quantity, delivery time, packaging |
| Project details | Rig model, drilling depth, use |
Meanwhile, our team will keep following up on customer needs and arrange production or technical talks as needed.
Looking Forward to the Next Journey
National Day is a celebration. At the same time, it is a reminder that progress comes from steady work. For Chenghui, the next stage stays focused on several simple goals:
- Better drilling tools
- More steady quality
- More practical customization
- Better technical support
- Long-term teamwork with customers worldwide
We will keep improving our PDC bits, tricone bits, core drilling tools, DTH tools and custom drilling solutions for different markets and jobs.
Because of this, from China to drilling sites around the world, we look forward to backing more customers in the years ahead.
Prosperous Celebration, Shared by Nation and Family.
Chenghui wishes everyone a joyful, peaceful and successful National Day holiday.
