The Drilling Manual

The Drilling Manual, Fifth Edition provides you with the most thorough information about the "what," "how," and "why" of drilling. An ideal resource for drilling personnel, hydrologists, environmental engineers, and scientists interested in subsurface conditions, it covers drilling machinery, methods, applications, management, safety, geology, and other related issues.

Most drill/drivers have a trigger to control how fast the drill spins, so for basic projects, a one-speed drill is all you need. If you need more precise speed control for diverse drilling or driving projects, a multi-speed drill like the BLACK+DECKER 20V MAX* Lithium-Ion 2-Speed Drill/Driver is worth a look. Use high speed for small, fast holes and driving and a low speed for high-torque applications like drilling large holes.

Simply, drilling is making a hole, and driving is securing a screw or other fastener. Drill/Drivers do both jobs, which is convenient for projects like hanging a mirror, where you might drill a pilot hole then drive in a screw.

Drilling technology has evolved substantially over the years, from slide rules and hand calculations to advanced computer science and numerical analysis. Volume II: Drilling Engineering, the first drilling content to be included in the Petroleum Engineering Handbook, is intended to provide a snapshot of the drilling state of the art at the beginning of the 21st century.

We offer our DM2000 / DM3000 Spraymist Kits as alternative to high pressure coolant.Operate with 100-125 psi of shop air pressure. Spindle speed will be same as Min psi above. Refer to our Speed & Feeds chart or our helpful Gundrilling Guidelines.

In 2010, the BYU school of engineering was approached by Village Drill founder, John Renouard, with the concept of the Village Drill, a manual borehole drilling device. The vision was quickly adopted by the BYU team, and soon thereafter the Village Drill was introduced to the world. The Village Drill team is proud to boast of the now over 103 drills operating in 36 countries across the globe, bringing water to hundreds of thousands in need of clean water.

The distal tibia is the preferred site for manual insertion. The needle is inserted on the medial surface of the tibia at the junction of the medial malleolus and the shaft of the tibia, posterior to the greater saphenous vein.

This Manual Drilling Machine features a powerful drill with continuous speed control and is easy to clean and transport making it ideal for use at a jobsite or in the shop. This product is electronically controlled and equipped with soft start, as well as temperature and overload cut-off systems. The drilling depth is easily adjusted by a stopper.

A hand drill is a manual tool that converts and amplifies circular motion of the crank into circular motion of a drill chuck. Though it has been replaced in most applications by power drills, the hand drill is used by many woodworkers.

When new pipe is to be installed or it is not possible to rehabilitate a pipe, so that it needs to be replaced but is in a congested area of buried infrastructure so that conventional methods such as bursting cannot be used safely, then a new or replacement PE100 pipe can often be installed by horizontal directional drilling. This method has a very small potential damage footprint provided that adjacent buried infrastructure can be accurately located.

This method is regularly used on distribution systems, which typically use small diameter mains, and on rural distribution systems it often enables mains to be installed alongside the carriageway without impeding traffic flow, as the drilling equipment is compact and self contained.

Where large parts of the route of the main are not accessible, such as for river crossings, horizontal directional drilling is a much less costly technique than tunnelling, and can be used for large diameters, such as trunk mains. For the larger diameters, the equipment is large, and requires support equipment such as generators and hydraulic power units.

This technique involves drilling a pilot bore, generally along a closely defined shallow arc, and then, if necessary, enlarging the bore using a reamer or hole opener to create a bore large enough to accept the new PE100 pipe, which is generally pulled in behind a reamer.

This picture shows a slant face drilling bit, also fitted with carbide tipped teeth that enable it to penetrate hard ground. Fluid can be pumped through the drill rods and out through jets in the bit to assist the operation

When drilling through harder ground formations and in rock a mud motor is used to drive the drilling bit independently of drill rod rotation. The mud motor is powered by the drilling mud pumped through the drilling rods.

On inaccessible projects such as river crossings or where the bore is at significant depth and where a surface receiver cannot be used, the drilling head location information is typically sent from the drill bit by a wireline system, via a wire running along the inside of the drill rods.

Smaller drilling rigs suitable for installation of smaller diameters pipes are self-propelled rigs, typically track mounted, requiring little in the way of additional support equipment. The size, complexity and need for additional support equipment increases generally as the pipe diameter and length increase. At the "maxi" end of the range, several loads of equipment are typically shipped to site and the site area required is a significant consideration.

These two images show a small directional drilling rig being unloaded to install 100 metres of 100mm PE distribution main, and in place ready to start drilling. It is using a simple flat blade slant face head for drilling in clay, the excavation being typically sized for man entry piecing up.

The route planning should include subsurface investigations/survey to identify ground conditions, so that appropriate equipment can be selected. It is also important to identify areas of poor or difficult ground, such as gravel and cobbles, which could allow the drilling mud to escape or create bore instability unless an appropriately engineered drilling mud can be used.

Because the operator of the drilling rig might not notice a momentarily excessive pulling force, a load link inserted between the swivel and the PE100 pipe to record pulling load can be used to record the maximum axial load exerted on the pipe. Certain users require weak links that fail before the pipe if overload occurs but this will result in a partly installed pipe with no means of completing the installation without major disruption, cost and delay. This is to be avoided if at all possible. The risk of scoring of the pipe can be minimised by ensuring the reamed bore is of sufficient diameter and properly cleaned and proved prior to pipe pull-back.

Whilst the drilling equipment is able to drill down from the surface at the start and come back up to the surface at the exit, there does need to be an excavation at each end to act as a sump for drilling fluid reclamation, but the most critical factor is to provide the space to transfer the new pipe from ground level down to the bore, and this will depend upon both the diameter and length of the installed pipe. The pipe must be appropriately aligned with the bore and at an appropriate bending radius to avoid any risk of kinking. 041b061a72
