Atlas Copco Overburden Drilling SystemsAs much as 90% of the land surface of the earth is covered with loose, unconsolidated material such as soil, clay, silt, sand, gravel and boulders, which varies in depth from a few centimeters to hundreds of meters.
Drilling through this so-called overburden is often problematic, due to the tendency of the earth to cave in behind the drill bit. This makes it difficult to retrieve the drill string after the hole has been drilled. In practice, the bore hole is often lost before a casing tube can be inserted to support it. The Symmetrix range of overburden drilling systems represent the latest technology in simultaneous casing advancement.
Drilled piles were first used in Italy, when repairing and reinforcing foundations of buildings that had been damaged during World War II. Drilling was originally done with rotary drill rigs and drilling tools were pipes with cutting teeth at the lower end. Pipes were rotated and pushed into the ground while circulating bentonite-water slurry as a drilling mud.
Over the years the engineering has improved and new equipment and technologies developed. With the introduction of percussive drilling methods, it became possible to penetrate all kinds of soil and rock.
In the early ’90s, the DTH method was used above all for well drilling. Well drillers had continuous problems with drill bits making work slow. When the drill bit hit a boulder it might cause deviation from drilling direction. In ad-dition the holes in overburden tend to collapse before reaching bedrock. Then a new casing drilling system, namely Symmetrix, was invented in Finland. Until the time the drilling was done with asymmetric drill bits, but the new invention was a symmetrical drill bit system, which advance a casing pipe simultaneously when drilling the hole.

The Symmetrix systemSymmetrix is a patented system comprised of an ingeniously simple concentric method of drilling through over-burden with casing. Symmetrix drills straight holes, in any type of ground conditions, at any angle and to depths beyond 100 meters.
The three main components of the system are made up of:
A pilot bit that drills away the center part of the hole and guides the drill string. The pilot bit is attached to any common DTH hammer shank or top hammer rod thread.
A casing shoe welded to the casing pipe which is pulled down by the impact of the hammer and pilot bit.
A symmetrical ring bit that is locked onto the pilot bit drills the void for the casing to advance down the hole. There are three different types of ring bit and cas-ing shoe assemblies;
A solitary ring bit with no connection to the ■ casing shoe.
A welding ring that holds the ring bit and casing ■ shoe together.
A factory assembled ring bit set with integrated ■ ring bit and casing shoe.
Drilling in overburdenCasings are installed into the overburden basically for two different reasons:
1. To create a conduit through the overburden for example;
gas, oil, water and geothermal wells ■utility lines ■starter casings for exploration ■grouting casings ■
2. To create foundation and support structures such as;piles ■forepoling, pipe roofs ■ground stabilization ■anchors ■
Depending on the use of the casing it is either left in the hole permanently or retrieved by pulling out. Symme-trix range includes systems for drilling both permanent and retrievable casings. In case of the permanent casing the ring bit is sacrificed and left in the bottom of the hole, while drilling retrievable casings all system com-ponents are retrieved for re-use.

Permanent or retrievable casings
Pile types in foundation drillingFoundation piles are generally divided in two different types, end bearing piles and skin friction piles.
End bearing pilesA very important factor which determines the choice of foundation and its design is formed by the geotechnical properties of the ground.
In many cases piles can be footed in a firm stratum, such as dense till or bedrock, in which case they will get most of their bearing capacity from the base and consequently be classified as end bearing piles. Solitary ring bits can be used in this type of drilling. In case there is a special need to tie the casing shoe and ring bit together (like cavities or soft clay in ground or where drilling starts over water surface) the connection can be made economically by using a separate welding ring. Ring bit and casing shoe can be integrated in the factory. These factory assembled ring bit sets are easy to use.
The systems are available through the whole product range the smallest being for 114 mm (4 1/2") casing and largest size available at the moment is for 1220 mm (48") casing.
Skin friction pilesWhere there is no particular dense underlying stratum, the bearing capacity will depend on the friction forces that are mobilized along the length of the pile. These piles are called skin friction piles. Casings are often retrieved after reinforcement structure has been in-stalled.Skin friction piles can be drilled with the solitary ring bit as above, pulling out the casing after the concrete is poured in, but more common is to use a system where also the ring bit is retrieved. Such systems always have large ring bit inner diameters to allow maximal inside diameter usage for reinforcement structure.
The same method can also be applied to well drilling for applications where casings are retrieved. Retriev-able systems are available for casing sizes from 89 mm to 1220 mm (3 1/2" to 48").

Large pass through inner
Common system requirements
diameterThere are casing drilling applications where the pas-sage through the ring bit is essential. Such requirement is typical in both piling as well as in well drilling. Symmetrix product range includes models taking this requirement into consideration.
In piling a large pass through ring bit inner diameter is normally required to drill a hole for a rock socket with-out the casing with a DTH bit. On the other hand the structure of pile reinforcement placed into the casing requires a certain space and when casings are retrieved ring bit inner diameter needs to be large enough.
In well drilling the casing is drilled through overburden into the bedrock and then the drilling of rock well is continued with a DTH bit. For that reason the ring bit inner diameter needs to be large enough.
Systems with drill-through pilot bitSometimes it is economically reasonable to drill the hole for the rock socket with the actual Symmetrix pilot bit. This applies to all cases where the rock socket length is short compared to the casing length. By utiliz-ing the Symmetrix pilot bit for drilling the rock socket, time is saved, since there is no need to replace the Sym-metrix pilot bit with a DTH bit between work phases. Symmetrix product family has such drill through sys-tems for both permanent and retrievable casings. Drill through systems are available for most casing sizes. In the product designation code, not only the ring bit inner diameter, but also the outer diameter of the pilot bit is given since the pilot bit makes a larger hole than the ring bit’s inner diameter.

Common system requirements
Heavy-duty systemsSymmetrix product family includes the heavy-duty system, which has very strong striking and pulling surfaces. In horizontal drilling the friction between soil and casing can grow very high and Symmetrix heavy-duty drill bits are designed to stand the abrasion in such conditions.
These systems are intended for break through drilling where the ring bit is recovered for re-use. System can be also used for drilling deep vertical holes, if there is no requirement on a large ring bit inner diameter.
Heavy duty systems are available for casings from 140 mm up to 1 220 mm (5 1/2" to 48").
Top hammer systemsWhile most of casing drilling is done with DTH ham-mers there are also requirements to drill casings with top hammers. Symmetrix product range naturally con-sists models for drilling both permanent and retrievable casings with top hammer.

Special system designs
Clay face designSometimes clay makes casing advancement very prob-lematic. Clay cannot be drilled with impact as its elastic structure does not break nor produce any cuttings to be flushed out, making penetration very slow. Hard, rubber type clays can be drilled with cutting only. For that rea-son Symmetrix clay face has been designed. Symme-trix clay version, which is optional for all models, has despite its large clay cutting face area enough surface with tungsten carbide inserts to allow also drilling into solid rock.
Sensitive conditionsWhen facing sensitive drilling conditions, such as un-derpinning and construction close to existing structures, pilot bits with extra deep face flushing grooves can be of great use. These Symmetrix pilot bits are used with long ring bit assembly to keep flushing within the face area and collect the cuttings back into the casing. This means less disturbances for surrounding structures. The method can also be utilized in marine constructions, where this assembly ensures controlled drilling and cuttings removal in sea bottom conditions. This sys-tem does not only keep the flushing under control but also allows accurate and straight penetration in steeply sloped bedrock face.

Special system designs
Symmetrix featuresEach Symmetrix system is made from high quality al-loy steel, and has been precision machined to produce a perfect bit body, heat treated to the required hardness, and fitted with durable tungsten carbide buttons.
Ballistic buttons for specific conditionsSymmetrix drill bits are manufactured with hemi-spherical buttons, but can be dressed also with ballistic buttons for use in soft and medium hard formations to achieve higher penetration rate. Ballistic buttons are efficient in cutting clay and also able to penetrate into wood when drilled within old wooden foundation.

When selecting the right Symmetrix casing drilling system, the first question to ask is whether the casing should be permanent or retrievable. This will influence the further choices.
The second issue to investigate is what casing size is used by determining outer diameter of the casing pipe and wall thickness. For permanent casing, both thick and thin wall casing can be used, while a thick wall casing is needed for retrievable casing.
The final step is to get a good insight of the application and requirements for the system. For example what kind of hammer is used? Is drilling continued through the ring bit after the casing has been installed? Is the drilling horizontal or vertical?
The Symmetrix systems will be named and numbered according to the casing type, casing size and ring bit in-ner diameter in both, permanent and retrievable forms.
How to select a Symmetrix system
1 . We need to know if the casings are left in the ground (Permanent) or are pulled out (Retrievable)
Permanent (P)
Retrievable (R)
Permanent - thin wall casing
Permanent - thick wall casing
Retrievable - thick wall casing
2 . We also need to know the casing outer diameter and wall thickness .
3 . We need to know the application require- ments, i .e .
- DTH or tophammer?
- Large pass through inner diameter?
- Drill-through system?

Rotation speedRotation speed depends on the size of the Symmetrix bit and also on the formation being drilled. The rotation speed may have to be varied as the formation changes. The harder the ground or the larger the bit the slower is the rotation speed e.g.
Air pressureRecommended air pressure in overburden is 12 – 14 bars.
