When using a center drill bit, it's essential to remember that they are not intended for deep drilling tasks. Their primary function is to create a shallow indentation, typically about one-third to one-half the diameter of the intended final hole. For this reason, they should be used with a lower speed and sufficient pressure to ensure a clean, accurate start without overheating the bit or the material.

  • The use of carbide drill bits is not limited to one specific industry; they are essential tools across various sectors. In woodworking, they provide a precise cutting edge for clean, splinter-free holes. In metalworking, they are indispensable for creating accurate holes in steel, iron, and other alloys without the typical challenges associated with high-speed steel bits. Even in the construction industry, carbide drill bits prove their worth by drilling through concrete, stone, and other masonry materials where standard drill bits would quickly dull or fail.

  • Crafted from high-carbon steel or more resilient materials like cobalt, the 75mm drill bit boasts a hard-wearing composition that ensures longevity. Its tempered surface resists corrosion and maintains a sharp cutting edge even under the relentless strain of contact with concrete, stone, or metal. A coating of black oxide or titanium can enhance this durability further, providing an additional layer of protection against the heat and friction generated during operation.
