1, determine the feed speed: feed speed is generally based on experience, from the numerical point of view generally 0.08-0.12mm/ RPM, or 0.6-1.0mm/ SEC, feed speed is a more critical element in drilling, different feed rates can form different iron filings, different iron filings will make chip removal performance changes 2. Positioning: Chisel a certain point in the center of the position that needs to be drilled or use a alloy needle to mark the "cross" line to ensure the accuracy of the drilling position. Note that when using the center chisel to set the anchor point, please ensure that the center chisel is perpendicular to the surface of the workpiece, so as not to affect the smooth discharge of the cutting core.

The working process of the drill
When digging, the drill rotates with the vertical axis and moves axially. The soil is cut under the torque and axial force of the drill bit, and is loosened under the extrusion and centrifugal force of the working blade, forming a soil flow pressure to the pit wall, while rising along the page to the surface. When the soil flow moves to the place without the barrier of the pit wall, the crushed soil is thrown around the pit due to the action of centrifugal force to complete the excavation process.

Drill is a kind of rotary and the head end has the cutting ability of the tool, generally to carbon steel SK or high-speed steel SKH2, SKH3 and other materials, milling or rolling and then after quenching heat treatment after grinding, used for metal or other materials on the drilling process. It has a wide range of use, and can be used in drilling machines, lathes, milling machines, hand electric drills and other tool machines. Drill bits can be divided into the following types according to different types.

TCI Rock Roller Tricone Bit with Water Well Drill Bit
tci(tungsten carbide insert). these tricones are designed for soft to very hard formations depending on the style and quantity of the carbides on the drill bit...because of its versatility and performance, it's still one of the main rock bits in use today. it is widely used for oil&gas, water well, geotechnical, environmental, geothermal, construction, exploration and mining drilling.

TCI tricone bits offer a variety of carbide inserts such as spherically shaped inserts for very hard rock or conically shaped inserts for softer rock. The number of rows of inserts is directly related to the type of application and the size of hole to be drilled. There are also open and sealed bearings available as well as three types of shirttail protection to choose from. TCI stands for Tungsten Carbide Insert. These tricone bits are designed for soft to very hard formations depending on the style and quantity of the carbides on the drill bit.

TCI Rock Tricone Bits for Water Well/Rock Drilling
Tricone Roller bit is the most widely used drilling bit. When the roller cone bit is working, the cutting teeth alternately contact the bottom of the well, the torque of breaking the rock is small, the contact area between the cutting tooth and the bottom of the well is small, the specific pressure is higher, and it is easy to eat into the formation; the total working length of the working blade is large, thus relatively reducing the wear. Roller bit can adapt to a variety of formations from soft to hard.
