Tired of late deliveries and dull drill bits?
You know the true cost of an unreliable supply chain. When your taper drill bits arrive late, or fail on your customer’s CNC machines, will destory your brand reputation . You need a taper drill bit manufacturer that guarantees industrial-grade precision, professional for OEM customization, and lighting-fast delivery. You need a partner who understands the strict demands of metalworking.
Here is exactly how partnering with a direct manufacturer transforms your B2B sourcing strategy.
We are a leading manufacturer of taper shank drill bits, offering wholesale and OEM solutions. We produce DIN 345 standard bits in HSS and M35 Cobalt for industrial metal drilling, ensuring precision, durability, and fast delivery for global importers.

I understand how supply chain delays and tool failures hurt your business and disappointed your customers. That's why we focus on strict standards, advanced materials, and efficient logistics. We want you to have a partner that delivers reliable, high-performance tools that keep your projects on schedule. Let me explain how our product range and engineering support your success.
Industrial Metal Drilling Standards: Core Specs of Taper Drill Bits
Your industrial clients do not buy on emotion; they buy on specifications. When you supply taper shank drill bits, you must meet strict international standards. Here is a breakdown of the core specifications you must demand from your manufacturer.
Taper shank bits follow DIN 345 standards and use Morse Taper (MT1-MT6) shanks for direct machine mounting. They are made from HSS or M35 Cobalt for different materials, and can have coatings like TiN or Black Oxide to extend tool life.

We invest in precise engineering to give you a product that fits your customers' machines and meets their expectations.
DIN 345 Standard and Morse Taper Sizes (MT1-MT6)
DIN 345 standard1 dictates the exact geometry, overall length, and flute length. The Morse Taper (MT) shank locks directly into the spindle of a drill press or lathe through friction, allowing for maximum torque transfer. You must match the drill diameter to the correct MT shank size.
High-Performance Materials: HSS vs. M35 Cobalt
The raw material dictates the lifespan of the tool. You must stock different grades for different applications.
- HSS 4241: Cost-effective for softer materials like aluminum and thin carbon steel.
- HSS 6542 (M2): The industrial standard for general metalworking, cast iron, and standard steel.
- HSS-Co M35 (Cobalt 5%): Essential for stainless steel, titanium, or hardened alloys. The cobalt allows the bit to stay hard at extreme temperatures.
Surface Coating Technology for Longer Tool Life
You can increase the value and life of your drill bits with the right surface treatment.
- Black Oxide: Reduces friction and holds lubricants. Prevents rust during shipping.
- TiN (Titanium Nitride): Gold-colored coating that increases surface hardness for high-speed production.
- Amber / Coffee Finish: A visual indicator of premium quality, favored in European and American markets for cobalt bits.
Professional OEM/ODM Services to Empower Your Hardware Brand
You are not just selling tools; you are building a brand. Buying generic tools leaves you vulnerable to price wars. You need a factory that acts as your invisible backbone, providing comprehensive OEM and ODM services.
We provide full OEM/ODM services including custom laser etching, non-standard size manufacturing, and branded packaging. This allows you to build a distinct brand identity and capture higher margins in your market.

Strong branding and customization protect your business from competition. We invest in flexible manufacturing to give you a product that carries your identity and meets your exact market needs.
Custom Laser Etching for Your Brand
Your logo needs to be on every tool. This builds long-term brand equity and prevents counterfeiting.
- High-Contrast Laser Marking: Your logo, SKU, material grade, and size are permanently etched onto the shank.
Flexible Non-Standard Size Customization
Your highest profit margins often come from supplying specialized sizes.
- Custom Diameters2: We can grind highly specific diameters like 28.7mm.
- Custom Overall Lengths (OAL): Extra-long flutes for deep hole drilling applications.
- Specific Point Angles: Request 135° split points for harder alloys to prevent the bit from "walking."
Custom Commercial Packaging Design to Boost Sales
Packaging dictates the first impression and must protect the product.
- Individual Protection: Bits are coated in anti-rust oil and packed in heavy-duty plastic tubes.
- Custom Color Labels: Tubes feature high-quality sticker labels with your brand colors and specs.
- Retail-Ready Display Boxes: Branded inner boxes for professional showroom displays.
Manufacturing Strength: ISO 9001 Certified Quality Control
Your reputation depends on the consistency of the factory you choose. A single batch of brittle drill bits can cost you your biggest client. You must partner with a facility that operates under strict quality control.
Our manufacturing follows ISO 9001 certified protocols, using precision CNC grinding, strict heat treatment, and 100% factory inspection. This ensures every drill bit meets exact hardness and concentricity standards before shipment.

Consistent quality protects your business from costly returns and machine damage. We invest in rigorous testing and controlled processes to give you a product that performs reliably every time.
Precision CNC Machining & Fully Ground Process
The manufacturing method defines the accuracy of the hole.
- Fully Ground (CNC Machined)3: For premium lines. Carved from a solid hardened blank for perfect symmetry and superior chip evacuation.
- Roll Forged: For budget-friendly, high-volume markets. Less precise but highly economical.
Strict Heat Treatment & Production Control
Heat treatment is the invisible differentiator. Incorrect treatment leads to instant dulling or shattering.
- Computer-Controlled Furnaces: Ensures exact Rockwell Hardness (HRC): M2 at HRC 63-65, M35 Cobalt at HRC 64-66.
100% Factory Inspection: Hardness & Concentricity Tests
The factory must test everything. You should not act as their quality control department.
- Rockwell Hardness Testing: Random sampling from every batch.
- Concentricity (Runout) Testing: Laser micrometers ensure perfectly straight shanks to prevent vibration in CNC machines.
- Destructive Drilling Tests: Routine verification of cutting speed and tool life on thick steel plates.
FAQ: Frequently Asked Questions for B2B Buyers
1. What is the main advantage of a Morse Taper shank?
The Morse Taper design allows the drill bit to mount directly into the machine's spindle without a chuck. This creates a strong friction fit that handles extreme torque, essential for drilling large holes in tough metals where a straight shank would slip.
2. Can you manufacture custom taper drill bits outside standard DIN 345 dimensions?
Yes. We handle custom requests for non-standard overall lengths, custom flute lengths, specific point angles (like 135° split points), and specialized coatings through our OEM solutions.
3. How do you guarantee the drill bits will not rust during ocean freight?
Every bit is coated in industrial-grade anti-rust oil, sealed inside moisture-resistant plastic tubes, packed in heavy-duty export cartons, and securely shrink-wrapped on wooden pallets to withstand sea transport.
4. What is the difference between HSS M2 and M35 Cobalt taper drill bits?
Supply HSS M2 for general-purpose metalworking (carbon steel, cast iron, aluminum). Use M35 Cobalt for abrasive or hard materials like stainless steel and titanium, as the cobalt prevents the cutting edge from melting under extreme friction.
5. What is the typical lead time for a bulk OEM order?
For standard sizes, lead times are 20 to 30 days. For larger bulk orders with custom OEM laser etching and branded packaging, the lead time is typically 30 to 35 days. You receive a precise schedule before confirming your order.
Conclusion
Sourcing taper drill bits for metal shouldn't be a gamble. By partnering directly with a professional manufacturer, you pass middlemen, secure better pricing, and gain full control over quality and branding.
