I bought one of those kits of drill bits from woodcraft when it was half price around Christmas (a few years before I bought the Fuller set) .
Sizes range from 1/16 up to (IIRC) 5/16 with a mix of Brad points and regular twist bits.

I found most of the real small bits were never quite straight.
I still use the set for non precision drilling, and the Fuller bits when I want round hole.

I guess I have used a lot over the years: Chicago Latrobe, Hanson, Cleveland, Big box (I lump all of them together, Millwakee, B&D, DeWalt etc, they all seem about the same to me), Vermont American, various eras of Craftsman, Morse, Union, a lot of generic imported sets, and more new and old brands I don't remember. The older USA-made, industrial-quality brands all were good. The main differences were the type of drill and what application it was specifically intended for. Sadly, a lot of those old American companies are either gone or exist only in name only.

I have a few specific preferences for the Norseman. The sides flutes are very sharp, making things like elongated holes much easier. You do have to be careful about cutting yourself though. They also have a slightly faster spiral than most bits, which I like for chip clearance in most materials. They are relatively easy to get and reasonably priced for the quality. They are also made locally in St. Paul

I don't know that I have used Fuller, if I did I wasn't aware. I generally don't look at the brand of the bit when grabbing one out of the drawer or set, and I have a lot of mixed sets in addition to my "good" Norsemans (Norsemen?).

I just tend to buy whatever brand they have at the store when it comes to twist bits. DeWalt, Milwaukee, Ryobi, Craftsman, Irwin, whatever. I've never felt one brand was significantly better than any other, so long as you stayed away from the no-name brands and Harbor Freight. And even those can be okay if you don't expect them to last long. I tend to focus more on the metal they're made out of. Choose the right metal for the job. I'd pick cobalt bits for drilling through metal. Twist bits are throw-away bits to me, so I'd rather have a bunch than spend a bunch on one.

I don't get brand loyal and start "investing" in bits until you get into Forstner, auger, or brad point bits. I find a much bigger difference between brands with these bits.

How to Choose Reliable Wholesale Drill Bit Suppliers for Industrial Applications

In industrial manufacturing, construction, and machining, drill bits are small but essential consumables. Their quality directly impacts work efficiency, durability, and cost control. For B2B buyers, partnering with the right wholesale drill bits suppliers is not just a purchasing decision—it’s a strategic move.

But with so many drill bit companies in the market, how do you identify the best drill bit manufacturer for your specific needs? In this guide, we’ll walk you through key evaluation points and share insights from within the industry.

1. Define Your Application: Different Jobs Require Different Drill Bits

Not all drill bits are created equal. Choosing the right type depends on what you're drilling:

• HSS drill bit manufacturers specialize in affordable, high-speed steel bits ideal for metalworking.

• A cobalt drill bits manufacturer offers bits that can withstand high heat, perfect for hard metals or high-load applications.

• Masonry drill bit manufacturers focus on drilling through tough materials like concrete or brick.

If you're working with rotary hammer tools, SDS masonry drill bits suppliers provide specially designed bits with superior fit and durability.

�� Pro tip: Clarifying your application early avoids costly mismatches and improves overall tool performance.

2. Evaluate Manufacturing Quality: What Really Matters

✔️ Materials & Workmanship

Whether you're buying from a china twist drill bit supplier or a china solid carbide drill bits supplier, always ask:

• Are high-purity HSS or solid carbide materials used?

• What kind of heat treatment process is applied?

• Is coating (like TiN or TiAlN) available for added durability?

✔️ Production Standards & Certifications

A qualified manufacturer of drill bits should follow strict quality control. Look for:

✔️ Customization Capabilities

Leading China drill bits manufacturers often support custom orders, allowing adjustments in diameter, flute length, shank type, or coating to match your tool requirements.

3. Why Choose China Drill Bit Manufacturers?

China remains a global hub for drill bit manufacturing, with several key advantages:

• Scale & Capacity: From HSS drill bit suppliers to china center drill bits suppliers, Chinese factories are equipped to handle large, repeat orders with consistency.

• Cost-Effectiveness: Without compromising on quality, Chinese-made drill bits often provide better value compared to Western brands.

• Full Product Range: Whether you need a china twist drill bit supplier or SDS masonry drill bits suppliers, China offers one-stop solutions for any material or drill bit format.

4. Build a Reliable Supply Chain: Tips for Long-Term Partnerships

• Start Small: Place a small trial order to test product consistency and delivery time.

• Prioritize After-Sales Support: Good drill bit companies offer technical assistance and flexible return policies.

• Maintain Communication: Regular updates with your drill bit supply partner help align forecasts and avoid inventory risks.

Choosing a drill bit supplier is about more than pricing—it's about trust, quality, and long-term cooperation. Whether you're sourcing from HSS drill bit manufacturers, cobalt drill bits manufacturers, or china SDS masonry drill bits suppliers, the key is to match your needs with a manufacturer that delivers on performance and reliability.

�� If you're ready to explore high-capacity, cost-effective suppliers, start with top-tier Chinese manufacturers. Their experience in wholesale drill bits production and scalable operations could unlock real value for your business.
