Best Top Hammer Drill Machine - Drill Tech International

 The Drilltech International  is a professional grade corded hammer drill which is available in 240v or 110v. Corded operation has historically provided more speed and power than battery powered designs, and unlike their cordless counterparts corded hammer drills won’t run out of power halfway through a job. 

They are usually a cheaper option as you don’t have to invest in batteries and chargers; however they are not particularly well suited to driving screws – it is rare to find any kind of torque control on a Top Hammer Drill Machine, and they are often slow to brake once the trigger is released. On top of this they are usually fairly large, heavy machines designed for two-handed operation, all of which makes them difficult to use with precision – especially in cramped spaces. Like corded rotary drills, hammer drills are often available in 110v or 240v – the 240v options can be used with standard household power sockets but the 110v versions can only be used with step down transformers as used on building sites and in other industrial environments.

Top Hammer Drill Machine Overview

1- Combination drill and countersinks (center drills), counter bores, reamers, taps, and other small shank cutters can also be supported in this way.

2- Tapered-shank twist drills may be held directly in the tailstock tapered spindle as long as a good fit exists. 

3- If the drill shank is not the correct size, then a drill socket or sleeve may be used in the tailstock spindle.

4- A twist drill holder is used to support large twist drills with the tailstock center.

5- The drill is inserted into the holder and the tailstock center is placed in the center hole which is located at the rear of the drill holder.

6- The holder will rest on the cross slide or compound rest and must be supported by hand until it is held secure by pressure between the tailstock and headstock. 

7- When using this method, never withdraw or loosen the tailstock spindle while the lathe is rotating or the workpiece can be thrown out at the operator. 

8- Always stop the machine before attempting to withdraw the twist drill.

9- Another method of supporting a large twist drill in the tailstock is to fasten a lathe dog to the drill shank and support the rear of the drill with the tailstock center in the center hole in the tang of the drill.

Top Hammer Drill Machine of Drilling operations

1-  Drilling is the production of cylindrical holes of definite diameters in work pieces by using a multipoint cutting tool called a drill. 

2- The drill chuck is mounted in a tailstock spindle and the feeding on the drill to work is done by rotating the tailstock hand wheel. 

3- To start the drilling operation, compute the correct RPM for the drill and bet the spindle speed accordingly. Ensure the tailstock is clamped down on the lathe. 

4- The feed is controlled by turning the tailstock hand wheel. 

5- The graduations on the tailstock spindle are used to determine the depth of cut. 

6- If a large twist drill is used, it should be preceded by a pilot drill, the diameter of which should be wider than the larger drill web. 

7- Use a suitable cutting fluid while drilling.

8- Always withdraw the drill and brush out the chips before attempting to check the depth of the hole. 

9- If the drill is wobbling and wiggling in the hole, use a tool holder turned backwards to steady the drill.

10- Always use a drill that is properly ground for the material to be drilled. 

11- Use care when feeding the drill into the work to avoid breaking the drill off in the work. 

12- Drill should never be removed from the work while the spindle is turning because the drill could be pulled off the tailstock spindle and cause injury or damage.

Boring 

1- Boring is the process of enlarging and truing an existing drilled or core hole with a single point cutting tool. 

Necessity of boring a hole 

1- To enlarge a drilled hole larger than the drill size as drills are available in standard sizes only. 

2- To obtain concentricity of the hole. 

3- To maintain accuracy of the hole. 

4- To remove the error formed by drilling, and to facilitate the remaining operation. 

5- To obtain better surface finish. 

Types of boring tools 

1- The following are the different types of boring tools. 

1- Solid forged tools. 

2- Boring bars with bits. 

3- Brazed tools. 

4- Throw away bits inserted in special holders. 

Advantages 

 1- Available with square and round shank. 

 2- Enable the tool to mount easily. 

3- Re-grinding is easy. 

4- As the tool is integral, alignment is easy. 

5- Can be easily forged to the required shape and angle.

What is Top Hammer vs Down the Hole - Drill Tech International

    Top Hammer vs Down the Hole essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock. As the drill string slowly rotates, the drilling hammer is forced into the rock repeatedly. Striking power is provided by compressed air driving a piston inside the hammer.

Where is it used?

DTH drilling is often used in the mining industry (blast hole drilling), on construction sites, drilling water wells, and in the oil and gas industry.

Top Hammer vs Down the Hole Advantages

Top Hammer vs Down the Hole offers several advantages over top-hammer drilling for larger, deeper holes in medium-hard formations. Because the hammer is at the bottom of the hole, power loss is minimal as the hole deepens. That means energy is not lost in the drill string and penetration rates do not markedly decline with depth—provided that back pressure does not rise significantly in the borehole. DTH drilling is most suitable for hole diameters of 4–10 inches, with some exceptions.

Compressed Air Power

The DTH hammer is pneumatically powered, with the compressed air propelling it forward to impact and fracture rock. Compressed air also travels through the drill bit into the hole (air exhaust), which blows the chips and dust out of the hole.

Quieter Drilling

From environmental and social perspectives, DTH is a good option because it produces much less noise and vibration than many other drilling methods.

Before drilling operations commence the driller should examine the extraction face from the bottom to look for geological problems, loose or shattered rock or dangerous overhangs, and areas of potentially reduced burden.

At the top of the quarry face the driller should check for ground stability issues, excessive cracking of the rock, shear planes or other potential rock failures.

If issues are identified then the Driller must raise these with the appropriate responsible person such as the Operator, Manager, Explosives Supervisor and Shotfirer and if necessary the blasting specification should be amended.

The Driller should thoroughly check their equipment prior to tracking into position, these checks should include the condition of the drill string and the drill bit/hammer, the operation of the dust extraction equipment, guarding of moving parts and the condition of hydraulic hoses.

The Driller should not commence any drilling operations unless adequate edge protection is in place at the quarry face. If the Driller is required to erect the edge protection then they must carry out such operations using suitably anchored fall arrest equipment.

"The traditional drilling bits can't last long enough, but developed special bits with diamond coated carbides that can perform in the desired way. That means one drill bit being able to drill typically about 3,000 - 3,300ft (900 - 1,000m), and it will be able to maintain the drilling performance well all the way towards the end of its life without sharpening". "While the diamond bit unit cost is clearly higher than a usual TH bit, it does offer an extremely good total cost per metre payback."

Together with the general improvements in the durability of drilling consumables, operators' ever prevalent desire to improve efficiency and the consequent continuous increase in drilling power are also creating new demands to the drilling string, especially the threads. As a response, the market is seeing new thread designs, like for example shoulder supported male/female thread, that many operators have found an improvement to the traditional thread designs.

However, it is not one specific innovation or application which will decide the efficiency and profitability of top hammer drilling on a specific project. the old skill of adding up all cost-determining factors and establishing the total drilling cost (TDC). "TDC is a sum of productivity cost of drilling in terms of time and cost per metre (drill string endurance)," he explains.

Energy saving is another key factor as sometimes drilling is set-up to drill with highest pressures, while not necessarily needed. In short, concludes, what needs to be focussed on is what can be done to increase productivity by increasing drilling speed, avoiding downtime and managing the lifetime of wear products.
