Bristol produces a wide range of drill bits and extensions for drilling, which are sized and designed according to the geological characteristics prevailing in the most different regions, as well as vary according to the type of service to be performed: micropiles, large foundations, electrification , etc.
| Type | Indicated | Height | Diameter |
|---|---|---|---|
| Simple Razor Auger | Soils with low levels of obstacles such as earthy, sandy and clayey. Tips and blades made of SAE 1070 carbon steel. | 2.000 mm | 150 a 1.400 mm |
| Claw Auger | Dense, embankment-like soils with small rocks or stones. Its cutting system is the same used in excavator shells. Consisting of the claw and the claw cover, they are produced in cast iron. | 2.000 mm | 150 a 1.400 mm |
| Furrower Auger | Hard, compacted soils. The Furrower reaches the ground before the razor, sheltering tears in the ground. Tips and razor and furrower are made of carbon steel SAE 1070. | 2.000 mm | 150 a 1.400 mm |
| Tungsten Auger Bits | Resistant soils of sedimentary geology, with the presence of stones, gravel or slate. Bits are made of tungsten, a material with high hardness and density. | 2.000 mm | 150 a 1.400 mm |
| Continuous Helix Auger | Drilling and injecting concrete into deep foundations. It has a helicoid in its entirety, which allows the extraction of the earth in one go, in addition to a channel for the passage of concrete inside it. | 2.000 mm até 12.000 mm | 250 a 500 mm |
| Pipe Auger | Base enlargement, for making shoes or pipe. Developed with the aim of providing compact and safe equipment, as it greatly reduces the risk of accidents due to landslides. It is widely used in foundations that support transmission towers and also in civil construction. | 2.000 mm | Closed from 500 mm to 1.500 mm / Open from 1.000 to 3.000 mm |
| Simple Extension | Extension with fixed length for 1 to 4 meter increase in drills. Its purpose is to carry out deeper foundations. | 1.000 a 4.000 mm | 80 mm |
| Telescopic Extension | Extension with variable length to increase from 2 to 8 meters in drills and augers. Its purpose is to create foundations with alternating depths, as it can be used retracted or elongated. | 2.000 a 8.000 mm | 80 a 100 mm |
