About this item

  • Precise Drilling: Upgraded four-flute sawtooth eccentric drill bit features a high-precision eccentric tip that helps reduce slippage, ensuring accurate hole starts and efficient drilling in materials like ceramic and tile
  • Hex Shank Grip & Multi-Tooth Cross Blades: The 6-flute anti-slip hex shank provides a secure grip, while the multi-tooth cross blades help facilitate cutting in concrete and masonry for better durability and cutting efficiency
  • Threaded Flute Design: The spiral chip removal grooves expand chip clearance and cooling space, making it suitable for dry drilling in materials like brick, wood, and metal at recommended speeds of 800-1000 RPM
  • Dual-Mode for Dry/Wet Drilling: This drill bit performs well in both dry conditions (such as ceiling drilling) at lower speeds or with water cooling to help maintain tool life when drilling tough materials like hardened concrete
  • Tips to Maximize Bit Life: Start with light pressure to position the bit, then gradually increase speed. Lift the drill at half-depth to clear heat and debris, helping extend the bit's overall performance


The four-flute sawtooth eccentric drill bit is made from high-hardness carbide for durability and precision.

Perfect for drilling through ceramic, tile, concrete, metal, wood, and brick.

Ideal for home renovation and DIY projects.
