Industrial hss twist drill bits

Start by selecting the required diameter, then consider the shank type and the intended use. In this selection, you’ll find drill bits in common diameters such as 3 mm, 5 mm, and 6 mm, along with longer options up to 20 mm with a reduced shank for thicker tool holders. Standard HSS bits are suitable for general drilling in metal, while PointTeQ versions and reduced-shank variants help you reach deeper holes or fit smaller chucks. Choose a length that matches your workpiece and the material you’re drilling.

A reduced shank lets you use longer drill bits with tool holders that have smaller chucks. In the visible offers, you can see shank sizes up to 20 mm and shank types such as Cylindrical tapered, with DIN 338 listed in some options. This setup affects access inside the workpiece and helps maintain drilling stability when using a limited chuck size. In practice, choose the type that matches the hole depth and the size of your tool holder.

DIY users will typically look for common sizes like 3 to 6 mm for simple drilling in soft metals and general applications. Professionals, on the other hand, may prefer longer drill bits and reduced-shank versions to reach deeper areas or drill thicker workpieces. In this range, you’ll also find sets that cover multiple diameters and formats with shanks designed for specific chucks, making it easier to choose based on your precision needs and how often you use the bits.

Clean them after each use and store them in a dry place to prevent corrosion. To improve performance, use the right lubricant during drilling to reduce overheating and achieve a cleaner cut. Regularly check that your chuck is compatible with the shank diameter (standard or reduced) and avoid impacts that could damage the tip. Store bits separately and protect the cutting edges to preserve sharpness.

The assortment includes options from Total, Bosch, and Harden, with different configurations suited to working with metal. Total offers various diameters like 3, 5, and 6 mm in standard series, while Bosch highlights reduced-shank bits for longer reach and specific requirements. Harden provides multi-size sets that are useful for covering multiple drilling sizes. In practice, mix brands based on access conditions, the needed length, and your comfort level, so you get efficient progress on your projects.

Choose a standard bit when your drilling depths are moderate and your tool holder can accept the shank diameter. If you’re working in tight spaces or need smoother drilling in thicker workpieces, choose a PointTeQ version or a reduced-shank bit, since they provide better stability and easier access. This set includes bits with an appropriate tip and extended shanks to handle these specific situations without sacrificing rigidity.
