Twist Drill Bits & Sets

Twist drill bits are versatile all rounders for drilling metal, wood and plastics.  High speed steel bits handle everyday drilling, while cobalt and titanium coated versions cut stainless steel and hardened materials.  Complete sets ensure you always have the right size.

What are twist drill bits used for?
Twist drill bits are the most common type of drill bit, used for general-purpose drilling in wood, metal, plastic, and composites. Their spiral flute design helps remove debris as the bit cuts into the material, making them ideal for a wide range of applications from construction and metalworking to home repairs and workshop tasks.

What materials and coatings should I consider when choosing a twist drill bit?

  • HSS (High-Speed Steel) – suitable for wood, soft metals, and plastics

  • HSS-TiN (Titanium-coated) – reduces friction and increases lifespan, ideal for repetitive drilling in metal

  • Cobalt alloy (HSS-Co) – designed for stainless steel and hardened metals

  • Black oxide – offers corrosion resistance and better wear in wood and mild steel
    Choose the material and coating based on the material you're drilling into and whether heat resistance or longevity is a priority.

Why should I buy a twist drill bit set instead of individual bits?
Drill bit sets offer a range of diameters in one kit, allowing for greater flexibility and convenience. They're ideal for tradespeople, workshops, and DIYers who work with varied hole sizes and materials. Sets often come in durable cases with size markings, making it easy to stay organized and replace bits as needed.
