Source factory-direct hole saws. No middlemen.

You are likely a procurement manager, tool distributor, or brand owner. You deal with complaints about stripped teeth, wobbly arbors, or delayed shipments. You need a partner, not just a vendor.

At Tenyu Tool, we remove the trading company markup. We manufacture industrial-grade hole saws designed for heavy-duty performance. From M42 Cobalt Bi-Metal for steel to Diamond tips for ceramic, our factory delivers consistency your customers can trust.

We are a leading manufacturer of hole saws, offering OEM and wholesale solutions. We produce Bi-Metal, TCT, and Diamond hole saws for metal, wood, and masonry, ensuring durability and performance for professional and industrial applications.

Factory production line for hole saws

I understand how product failures and supply issues hurt your business. That's why we focus on material quality and manufacturing precision. We want you to have a partner that delivers reliable, high-performance tools that protect your brand reputation. Let me explain how our product range and engineering support your success.

Premium Hole Saw Series: Engineered for Durability & Speed

We don't just stamp metal; we engineer cutting solutions. Our product line covers every application, from general construction to industrial fabrication.

We offer three main types of hole saws: durable Bi-Metal for general use, long-lasting TCT for hard materials, and precise Diamond for masonry. This allows you to stock a complete solution for all your customers' cutting needs.

Assortment of Bi-Metal, TCT, and Diamond hole saws

A complete product line makes you a primary supplier. We provide that variety, so you can meet the demands of any job, from plumbing and electrical work to metal fabrication and tile installation.

Bi-Metal Hole Saws (M3 & M42 Cobalt)

This is the workhorse of the industry. But not all Bi-Metal is created in good quality.

  • M42 Grade (8% Cobalt)1: This is our flagship specification. The cutting edge contains 8% Cobalt, providing superior heat resistance.
  • Application: Essential for cutting stainless steel, cast iron, and hard metal.
  • Hardness: Heat-treated to HRC 63-65.
  • Life Span: Lasts 30% longer than standard M3 saws in high-heat applications.
  • M3 Grade: A cost-effective solution for general contractors.
  • Application: Mild steel, wood, plastic, and drywall.
  • Advantage: Excellent balance of flexibility and cutting power for non-industrial users.

TCT (Tungsten Carbide Tipped) Hole Saws

When Bi-Metal fails, TCT succeeds. Designed for materials that destroy standard steel teeth.

  • Carbide Technology: We use ultra-hard YG8 Tungsten Carbide tips brazed onto a high-strength alloy body.
  • Triple-Edge Tooth Geometry: Our specific tooth design splits the chip load.
  • Outer/Middle/Inner Teeth: This distribution reduces cutting resistance by 50% compared to standard flat teeth.
  • Target Materials: Thick Stainless Steel plate (up to 25mm), Fiberglass and FRP, Hard Plastics.
  • Why Buy TCT? For industrial users, the cost-per-hole is significantly lower than Bi-Metal due to the 10x lifespan extension.

Diamond Hole Saws & Core Bits

Precision tools for fragile and abrasive materials where impact must be minimized.

  • Electroplated Diamond: High diamond concentration on the edge. Best for glass and standard ceramic tiles. Fast cutting, smooth finish.
  • Vacuum Brazed Diamond: A premium option. The diamonds are chemically bonded to the metal.
  • Advantage: Can be used Dry (without water cooling) in many applications. High heat tolerance.
  • Application: Porcelain tile, granite, marble, and stone counter-tops.

Why Choose Tenyu Tool as Your Hole Saw Manufacturer?

Many suppliers are trading companies posing as factories. We are a real manufacturer. Here is the reality of our production floor and quality commitment.

We enforce strict quality control, including automatic laser welding and 100% inspection. This ensures you receive safe, high-performance hole saws that protect your customers and your brand reputation.

Automatic laser welding machine for hole saws

Consistent quality protects your business from costly returns and safety complaints. We invest in rigorous processes to give you a product you can trust and sell with confidence.

Advanced Manufacturing: Automatic Laser Welding Technology

The weakest point of a Bi-Metal hole saw is the weld process.

  • The Old Way: Manual welding often leads to uneven seams that crack under torque.
  • The Tenyu Way: We utilize Automatic Laser Welding Lines2.
  • Benefit 1: The seam is microscopic and perfectly fused.
  • Benefit 2: The Bi-Metal strip (HSS edge + Spring Steel back) is welded with uniform heat distribution, preventing the "brittle zone" that causes teeth to snap off.

Strict Quality Control: 100% Inspection Before Shipment

We don't rely on "batch checking" alone. Every single unit goes through critical checkpoints.

  1. Run-Out (Wobble) Test: We verify the concentricity of the saw base. A wobbly saw breaks drill bits and ruins workpieces. Our tolerance is stricter than industry standards.
  2. Torque Stress Test: We randomly select saws from the line and subject them to extreme torque until failure. This ensures the base plate will not detach from the cylinder under heavy load.
  3. Hardness Testing: We verify the HRC (Rockwell Hardness) of the teeth every hour to ensure the heat treatment oven is stable.

High-Grade Raw Materials Supply Chain

A saw is only as good as the steel it is made from.

  • We source our High-Speed Steel (HSS) and Spring Steel backing strips from top-tier suppliers.
  • We do not use recycled scrap steel for the cutting edge. This commitment ensures that a hole saw bought in January performs exactly like one bought in July.

Custom OEM & Private Label Solutions for Global Brands

Your brand is your asset. We are the silent engine behind it. We help you build a brand that stands out on the shelf and in the professional's toolkit.

We provide full OEM services, including custom laser marking, color coating, and branded packaging. This allows you to build a distinct, high-value product line under your own brand name.

Custom branded hole saws with laser etching and color packaging

A strong brand identity builds customer loyalty and profits. We help you create that identity with professional marking and attractive packaging, making your products memorable and desirable.

Custom Branding & Laser Marking

Stop using cheap stickers that peel off before the customer uses the tool.

  • Fiber Laser Marking3: We etch your Logo, Part Number, and Size directly onto the paint. It looks professional, permanent, and premium.
  • Custom Colors: Don't settle for generic red or white. Provide your Pantone code (e.g., Milwaukee Red, Makita Blue, DeWalt Yellow), and our automatic painting line will match your brand identity perfectly.

Customized Packaging Options (Color Box, Blister, Head Card)

Packaging drives retail sales. We offer flexible options based on your channel:

  • Double Blister: Best for hardware stores (Home Depot style). Prevents theft and protects the product.
  • Color Box: Ideal for kits and sets. High surface area for branding and instructions.
  • Plastic Tube/Hanger: Cost-effective for bulk sales to contractors.

Flexible Color Coating & Surface Treatment

  • Gloss/Matte Paint: Standard corrosion protection.
  • Sandblasting: For a rugged, industrial look.
  • TiN Coating (Titanium Nitride): Gold color. Increases surface hardness and reduces friction for premium product lines.

FAQ: Frequently Asked Questions for B2B Buyers

1. What is your Minimum Order Quantity (MOQ) for OEM?

We are flexible to support growing businesses. Generally, the MOQ for private label (laser logo) is 500 pcs per size. For fully custom color boxes, MOQ may vary. Contact us for a specific breakdown.

2. Can you provide samples for quality testing?

Yes. We encourage it. We can send free samples of our Bi-Metal or TCT saws so you can run comparative tests against your current supplier or big brands. You only cover the air freight.

3. What is the typical lead time for a bulk order?

For standard items in stock, we ship in 3-5 days. For OEM production orders (custom paint/packaging), the standard lead time is 25-35 days after artwork confirmation.

4. Do you sell directly to end-users (DIYers)?

No. We are a B2B factory focused on Wholesalers, Distributors, and Importers. This protects your market margins. We do not compete with our clients.

5. How do you handle defective products?

In the rare event of a manufacturing defect, we have a 1:1 replacement policy. We stand behind our quality 100%.
