Reliable bits, stable supply, higher profits for your business.
As a procurement manager or tool importer, you know the frustration of "cheap" drill bits: unstable carbide quality, heads snapping under heat, and fluctuating lead times that ruin your reputation with contractors.
We are a leading masonry drill bits manufacturer offering wholesale and OEM solutions. We produce high-performance SDS, straight, and hex shank bits with premium YG8C carbide tips for durability and consistent supply for global distributors.

I understand how product failures and shipping delays hurt your business. That's why we built our factory to control quality and delivery. We want you to have a partner you can trust for strong, reliable bits that arrive on time. Let me show you how our product range and manufacturing process support your demands.
Industrial-Grade Masonry Drill Bits for Global Distributors & Importers
Your customers need bits that work in different materials and with different tools. You need a supplier that offers a complete range to cover all their needs.
We manufacture a full range of masonry drill bits, including SDS Plus, SDS Max, straight shank, and hex shank options. Our bits are designed for concrete, brick, and stone, providing reliable performance for professional and DIY users.

A complete catalog makes you a primary supplier for your customers. We provide that variety, so you can source for all masonry drilling applications.
Precision-Engineered SDS Plus & SDS Max Shank Series
Our SDS range is the backbone of heavy-duty construction. We use high-grade 40Cr alloy steel1 for the shank to ensure maximum energy transfer from the rotary hammer to the tip without deformation.
- SDS Plus: Ideal for general masonry, brickwork, and light concrete.
- SDS Max: Engineered for heavy-duty demolition and deep-hole drilling in stone.
Straight Shank and Hex Shank Options for Different Applications
For the retail and DIY sectors, our straight and hex shank bits offer universal compatibility with standard chucks and impact drivers. These bits feature a precision-ground flute to ensure rapid dust extraction, preventing overheating during continuous use.
High-Performance Carbide Tipped Technology for Concrete and Stone
The "heart" of our drill bit is the YG8C Tungsten Carbide tip. Unlike competitors who use recycled alloys, we use virgin carbide powder to ensure the tip stays sharp 20% longer. This means your customers get more holes per dollar spent.
Full OEM/ODM Solutions: Custom Branding and Packaging
We understand that for an importer, the brand is your most valuable asset. Our factory isn't just a production line; it’s your personal R&D and packaging department.
We provide complete OEM services, including private label laser marking and custom packaging. This allows you to build your own brand identity with unique products tailored to your market's needs.

Building a strong brand leads to customer loyalty and better margins. We help you create that brand by offering full customization, from the product itself to how it is presented on the shelf.
Private Label Laser Marking on Drill Bit Bodies
We offer high-precision laser etching2 for your logo, size markings, and "Made in China" or "Germany Standard" designations. This ensures your brand remains visible even after the bit has been used in the dirt and dust of a construction site.
Tailored Packaging Designs: From Bulk Packs to Retail-Ready Display Boxes
Your packaging needs to fit your sales channel:
- For Distributors: Industrial bulk packs (plastic tubes or bags) to minimize shipping costs.
- For Retailers: High-impact skin cards, sandwich hangers, or color-coded plastic cases designed to grab attention on the shelf.
- For E-commerce: Minimalist, sturdy packaging optimized for "last-mile" shipping to reduce breaking and returns.
Flexible MOQ for Custom Specifications and New Market Testing
While we operate at a massive scale, we remain flexible for our long-term partners. We offer manageable Minimum Order Quantities (MOQs) for new size launches or experimental coatings, allowing you to test market demand without heavy inventory risk.
Why Partner with Tenyu Tool: Our Manufacturing Excellence
In the B2B world, a "good price" is useless if the quality varies between batches. We focus on consistency.
Our manufacturing is ISO 9001 certified, and we use advanced vacuum brazing and strict quality control. This ensures every batch of bits meets high standards for performance, durability, and safety before shipment.

Consistent quality protects your reputation and reduces costly returns. We invest in certified processes and rigorous testing to give you confidence in every order you place.
Advanced Vacuum Brazing Process for Superior Tip Retention
The number one complaint in masonry drilling is the tip falling off. Tenyu Tool utilizes Automatic Vacuum Brazing technology. By bonding the carbide tip3 to the steel body in a controlled, oxygen-free environment at high temperatures, we create a bond that is virtually unbreakable under standard thermal stress.
Large-Scale Production Capacity to Ensure On-Time Delivery
With over 30 sets of fully automated CNC grinding and brazing machines, our monthly capacity exceeds 1.5 million pieces. For you, this means "On-Time Delivery" isn't a slogan—it’s a contractual guarantee. We help you avoid "out of stock" scenarios that drive your customers to competitors.

Metric and Imperial Size Availability
Whether you are serving the European market4 (Metric) or the North American market (Fractional/Imperial), we provide precise sizing to meet local building codes and fastener requirements.
FAQ: What Professional Buyers Ask
1. Can you match the performance of Tier-1 European brands?
Yes. Our premium 4-cutter SDS series is specifically designed to compete with high-end brands in terms of drilling speed and hole accuracy, but at a significantly lower manufacturing cost.
2. Do you support customized hardness for specific regional stones?
Absolutely. If your market deals primarily with high-quartz granite or volcanic rock, we can adjust the tungsten carbide cobalt content to optimize for impact resistance or abrasive wear.
3. What is your standard lead time for a 20ft container?
Typically 30-45 days. For repeat OEM orders with forecasted volumes, we can reduce this to 20-25 days by maintaining raw material buffers.
4. How do you handle quality claims?
We stand behind our tools. If a batch fails to meet the agreed-upon technical specs, we offer a 1:1 replacement or credit. Our defect rate is currently below 0.3%.
5. Is it possible to visit your factory?
We welcome all partners to visit our facility. If you cannot travel, we can arrange a live video tour of our production and QC departments.
