Types of Drill Bits

Drill bits are essential cutting tools used in drilling holes across various materials, including wood, metal, masonry, tile, and glass. Choosing the right type—such as Twist Drill Bits for general use, Masonry Drill Bits for concrete, or Tile Drill Bits for ceramics—ensures efficiency and precision. Specialized options like Forstner Bits (for clean wood holes), Hole Saws (for large openings), and Cobalt Drill Bits (for hard metals) cater to specific needs.

Key Notes

HSS (High-Speed Steel): Durable for metal/wood.
Carbide/Tungsten Carbide: Harder, ideal for masonry/tile.
Cobalt Alloy: Heat-resistant for tough metals.
Diamond-Coated: Best for glass/ceramics.
