Designed for optimum performance is impact drivers

Armeg’s new Twister masonry drill bits are designed for optimum performance within impact drivers. Specially manufactured with a granite grind to the tungsten carbide tip, the drill bits are perfect for rotary only drilling under torsional impact. Twister masonry drill bits are available in 5 sizes with overall lengths of 150mm and working lengths of 95mm. 

  • ¼” Quick-Change Shank Drill bits can be rapidly interchanged within power tools (including impact drivers) for convenient and hassle free drilling
  • High Quality alloy Steel Provides durability and strength for the drill bit to withstand the torsional impact of an impact driver
  • 1 Piece Body Construction Ensures concentricity of the drill bit during the drilling process for more accurate holes and a secure fixing fit
  • Copper brazed at 1100°C Furnace brazing process uses a copper braze at 1100°C giving the ultimate bond between body and tip, allowing the drill bit to perform longer and produce a greater number of holes
  • Custom-Ground Drill Tip Designed specifically for rotary only drilling, the custom-ground drill tip reduces the torque placed on the drill bit resulting in faster and more efficient drilling in impact drivers

Twister Masonry Drills perform best in an impact driver when free rotating rather than when the power tool is ratcheting. Ratcheting can be minimised by reducing pressure and withdrawing the drill bit from the hole periodically.
