The drill bit does the real work — the machine simply rotates the bit. Selecting the correct bit type for the job is critical to performance and precision, whether you are drilling timber, metal, masonry, or composites.
The bit’s geometry, length, and cutting profile directly influence hole quality, drilling speed, heat buildup, and the lifespan of both the bit and the drill. A well-matched bit reduces breakage, improves chip evacuation, and minimises wear on your tools and workpieces.
When you match the bit to the material and application, you gain cleaner edges, reduced tear-out, and more consistent results — all while improving safety and reducing rework.
The flute design refers to the grooves that spiral up the body of the drill bit. These channels are responsible for carrying chips and dust out of the hole as you drill.
Efficient flute geometry improves chip evacuation, reduces friction, and helps prevent clogging and overheating. The right flute design allows you to drill faster and deeper while maintaining clean, accurate holes.
The cutter type at the tip of the bit determines how it engages with the material. Different point angles and cutting edges are optimised for timber, metal, masonry, plastics, and more.
Using the correct cutter style ensures smoother entry, better centring, less wandering, and a reduced risk of burning, chipping, or breakout, especially in delicate or brittle materials.
The material a drill bit is made from has a major impact on its performance, durability, and suitable applications.
Selecting the right bit material for your application helps you balance cost, speed, and tool life, ensuring you get the most from your drill and maintain consistent, high-quality results.
