China Carbide Tool Manufacturer | OEM & Custom | Tenyu Tools

Stop overpaying middlemen. Get factory-direct tools today.

Are you struggling with inconsistent tool life, delayed shipments, or trading companies that cannot answer technical questions? You are not alone. As a procurement manager or distributor, your reputation depends on the quality of the tools you sell.

Tenyu Tools is your direct factory partner in China. We manufacture premium solid carbide cutting tools—end mills, drills, burrs, and custom solutions—that give you a competitive edge with your customers, protecting your profit margins through superior quality and direct pricing.

I speak with distributors every week who are frustrated. They're tired of promises that don't match the product they receive. At Tenyu, we built our business on transparency. What you see in our catalog is what we make on our machines. Let's get into the details of how our product lines can strengthen your offering.

Our Premium Solid Carbide Cutting Tool Product Lines

You need a complete catalog to satisfy your diverse customer base. From aerospace workshops to general mold making, our production lines cover the full spectrum of CNC cutting applications. We don't just "stock" these items; we engineer them using premium micro-grain tungsten carbide rods.

We offer a comprehensive range of application-specific carbide tools. Each line is engineered with distinct geometries, coatings, and edge preparations to maximize performance in its target material, ensuring your customers achieve longer tool life and better finishes.

Offering the wrong tool for the job damages your reputation. A drill meant for aluminum will fail in stainless steel. We eliminate this guesswork by designing for specific challenges.

High-Performance Carbide End Mills for Steel & Aluminum

Milling is the backbone of modern machining. Your customers demand end mills that don't chip prematurely and provide an excellent surface finish. We produce specific geometries optimized for different materials.

• For Steel & Stainless Steel (HRC 45-65):
  • Variable Helix Design: We use unequal indexing (35°/38°) to reduce vibration and chatter during heavy cutting. This allows your customers to run machines faster.
  • Coating: Our premier AlTiN and TiSiN coatings provide extreme heat resistance (up to 900°C), extending tool life in dry machining.
  • Edge Prep: Every tool undergoes a honing process to strengthen the cutting edge, preventing micro-chipping.
• For Aluminum (Non-Ferrous):
  • Polished Flutes: We use a specialized "Mirror Finish" grinding process on the flutes. This is critical for aluminum to prevent chip welding (material sticking to the tool).
  • High Helix Angle (45°/55°): Ensures rapid chip evacuation, allowing for high-speed machining (HSM) strategies.
  • Design: 3-flute geometry with U-shaped gullets for maximum material removal rates.

Tungsten Carbide Rotary Burrs & Die Grinder Bits

For your customers in fabrication, welding, and foundry industries, we offer a comprehensive range of rotary burrsFor your customers in fabrication, welding, and foundry industries, we offer a comprehensive range of rotary burrs¹.

• Cut Styles:
  • Double Cut (Cross Cut): The most popular choice for general steels. It produces small chips for better operator control.
  • Single Cut: For heavy material removal on hardened steel.
  • Aluma Cut (Aluminum Cut): Wide flute spacing to prevent clogging when grinding soft materials like aluminum and plastics.
• Shapes: A full library including Cylindrical (Shape A), Ball Nosed (Shape C), Tree (Shape F), and Conical (Shape M).

Expert OEM & Custom Tooling Solutions

This is where Tenyu Tools truly separates itself from a standard "stock seller." We know that many of our clients are distributors building their own brand. We operate as your Silent Partner. Your customers will never know the tools were made in Danyang; they will only see your brand's quality.

We function as your dedicated manufacturing arm. From private labeling to full custom design, we provide the flexibility and confidentiality you need to build a powerful, branded tooling business without the capital investment of a factory.

Custom Tool Design: From Blueprint to Production

When your end-user sends you a drawing for a weird step-drill or a form cutter, don't turn down the order. Send it to us.

• The Process:
  1. Send Drawing: Upload PDF or CAD (DWG/DXF).
  2. Engineering Review: Our engineers check feasibility. We advise on the best substrate and coating for the intended material.
  3. CAD Simulation: We simulate the grinding path to ensure the geometry is correct before a wheel touches the carbide.
  4. Production: We manufacture the tool exactly to your print.

Why Choose Tenyu Tools as Your Manufacturer?

The internet is full of "trading companies" posing as factories. They take your order, shop around for the cheapest workshop, and send you inconsistent products. Tenyu Tools is different. We invite you to visit our facility in Danyang or schedule a video tour. Here is the hardware backing our promises.

Our investment in world-class machinery and rigorous quality control is your guarantee of consistency. We manufacture precision into every tool, then verify it with automated inspection, ensuring every shipment meets the same high standard.

I tell every potential partner: "Judge us by our machines and our process, not just our price list." The tools are a result of the technology we use.

Quality Control: 100% Inspection with Zoller Genius

Quality is not "checked into" a part; it is manufactured into it. However, verification is mandatory. We do not do "random sampling" for critical dimensions.

• **The Zoller Genius Quality is not "checked into" a part; it is manufactured into it. However, verification is mandatory. We do not do "random sampling" for critical dimensions.
• The Zoller Genius³: This is our primary measuring device. It is a fully automated optical measuring machine. It measures:
  • Outer Diameter (OD) tolerance.
  • Runout / Concentricity.
  • Rake angles and relief angles.
  • Gash dimensions.
• The Promise: If a tool does not pass the Zoller check, it does not go into the box. We provide inspection reports with batch orders upon request.

Frequently Asked Questions (FAQs)

Q1: How do you ensure consistent quality across different batches? A: Consistency is our top priority. We use a strictly controlled "Fixed Process" method. This means once a tool design is approved, the grinding program, wheel selection, and raw material rod (e.g., from the same sintering batch) remain locked for all future re-orders. We also retain a "Golden Sample" from your first shipment to compare against future production runs, ensuring the 1000th tool performs exactly like the 1st.

Q2: Can you provide "Speeds and Feeds" data for my customers? A: Yes, absolutely. We act as your technical partner. For every series of end mills or drills, we provide detailed parameter charts including recommended cutting speed (Vc), feed per tooth (fz), and depth of cut (Ap/Ae) optimized for specific materials like Stainless Steel, Aluminum, or Hardened Steel. You can brand these charts with your logo to share with your end-users.

Q3: Do you offer free samples for performance testing? A: Yes, we encourage testing. For standard stock items (such as 4-flute end mills or standard twist drills), we offer free samples. You only need to cover the international shipping cost (or provide your DHL/FedEx account number). For custom-made tools, a small setup fee may apply, which is refundable upon placing a bulk order.

Q4: What file formats do you need for OEM laser marking? A: To ensure the sharpest logo reproduction on the tool shank, we require vector files. Please send your logo in .AI, .EPS, .CDR, or .PDF format. If you only have a JPG or PNG, our design team can help convert it to a vector format for you free of charge.

Q5: What are your payment terms for international orders? A: For small orders or sample costs (under $1,000), we accept PayPal or Western Union for speed. For standard commercial orders, our terms are typically T/T (Telegraphic Transfer): 30% deposit to start production, and 70% balance before shipment. For established partners with regular high-volume orders, we can discuss L/C (Letter of Credit) or open account terms after a credit review.

Q6: How do you handle shipping and customs for us? A: We offer flexible shipping terms based on your needs: EXW, FOB, CIF, or DDP.

• Express: For packages under 45kg, we use DHL/FedEx/UPS (3-5 days).
• Air Freight: For 45kg-100kg urgent orders (7-10 days).
• Sea Freight: For bulk stock orders (25-35 days). If you are new to importing, we recommend DDP (Delivered Duty Paid), where our forwarder handles all customs clearance and taxes, delivering the goods directly to your warehouse door.
