This technical guide explains the operational principles of multi-material drill bits, detailing the roles of tungsten carbide tips, ground geometry, flute design, and shank types. It outlines application maps for concrete, brick, and tile, emphasizing that bit selection must prioritize the hardest substrate and machine compatibility rather than treating all materials equally.
Questions to discuss with your supplier
Which specific tungsten carbide grade balances hardness and toughness for your most abrasive substrates? How does the flute geometry manage debris in deep holes across mixed materials? What shank dimensions and torque limits define the safe operating envelope for your handheld tools?
