High speed steel bits

Choose the category by the material you plan to drill. For metal, select high speed steel bits designed for metal use, for wood, pick bits made for wood or multi-material work, and for mixed jobs, consider multi-material or step drill sets. Look for sets labeled as HSS drill bit sets with coverage like 1-13mm or similar ranges to fit common tasks, and consider shank type (hex or straight) for your drill. Pair your choice with a coating or finish that suits your frequency of use to improve durability.

The most complex attribute is the flute design and tip geometry, including helix angle and point style, which control heat removal, chip evacuation, and starting accuracy. A sharper tip (like a split-point) reduces wandering, while a higher number of flutes can improve smooth cutting in metal or wood; drill bits may also vary in helix angle for faster or cleaner drilling. When choosing sets, you’ll see options like standard HSS bits with multiple flutes, or specialty step or cobalt-enhanced designs; understanding these helps you pick the right bit for your material and drill speed. In our listings, you’ll find HSS drill bit sets and step drill sets that illustrate these differences.

Beginners should start with versatile, easy-to-use high speed steel bit sets that cover common sizes and simple tasks, such as 6-piece or 20-piece HSS drill bit sets for metal and wood. Pros typically opt for higher-grade options, like cobalt or premium HSS, with broader size ranges and robust shanks (for example hex-shank designs) to withstand frequent use. Consider the task frequency and material types you encounter to choose between entry-level HSS sets and more advanced options in our catalog.

Maintain high speed steel bits by keeping them clean, dry, and sharp to prevent overheating and dullness. Use proper drill speeds for the material and apply light lubrication when needed, especially on metal, to extend bit life. Ensure the bit is properly seated in the chuck (tighten firmly) and choose the correct diameter and pilot hole to avoid stress. Store bits in a dedicated case or box and inspect for wear before reuse.

Look for genuine high speed steel (HSS) bit sets with clear size ranges (for example 1-13mm) and piece counts, plus shank type (hex or straight) and the included materials. Check for multi-material and wood-friendly options, straight or stepped designs, and any coating or finish that suits your usage. In this catalog you’ll see HSS drill bit sets and step drill sets, along with some cobalt-grade options, so choose based on your material and required durability.
