As a professional manufacturer, we produce these DIN 338 HSS roll forged drill bits for industrial use. We use high-quality high-speed steel (HSS) to ensure the tools stay sharp and last a long time. Our factory controls every step of the production process. This allows us to provide stable quality for every batch. These drill bits are perfect for drilling through metal, alloy steel, and cast iron.
We use the roll forging method to shape these drill bits at high temperatures. This process does not cut the metal grain; instead, it follows the spiral shape of the flute. This makes the drill bits very tough and flexible. Because they are less brittle than ground bits, they do not snap easily during heavy work. This durability reduces costs for your customers and improves safety on the job site.
Our products strictly follow the DIN 338 standard for dimensions and performance. We offer various surface treatments, such as black oxide, white, grey and so on, to prevent rust and reduce heat. These drill bits provide the best balance between high performance and low cost. They are the ideal choice for wholesalers and distributors who need reliable tools for the construction and hardware markets.
