DTH Button Bits
Pneumec “Down the Hole” Button Bits are manufactured from the highest quality European steels and carbides. They undergo rigorous inspection checks throughout their manufacture providing you with a high performance, dependable cutting tool.
Pneumec Button Bits are available in a wide range of sizes to suit most drilling applications and the different types of pneumatic hammers. Because Pneumec realizes your cutting needs are sometimes very varied we produce three shapes of cutting head as shown below. Our Button Bits are normally fitted with Hemispherical Buttons as these offer good cutting characteristics for most ground conditions. However should you require Ballistic or Parabolic, or a combination of two shapes, then these can be provided upon request.
DTH bits are available from 90mm diameter up to 1200mm diameter. You can also choose different profiles for tungsten carbide and face design to suit your application.
