The wide range of applications and drilling conditions<\/h2>\n\n\n\n

Suitable for\u00a0rock drilling tools. The\u00a0pneumatic percussion technique requires consideration of more than one type of tool to drill efficiently and profitably. A variety of factors, from hammer size to determining whether or not an economy hammer represents the best value, all figure into the hammer\u2019s overall cost of operation on a given job.<\/p>\n\n\n\n

How to Choose correct Bit Head Design for DTH drill bits<\/figcaption><\/figure>\n\n\n\n

Top hammer drilling is powered by intensive impact power produced by air or hydraulic pressure via a piston; the impact power is transmitted to the drill bit and finally into the rock via the shank adapter, coupling, and drill rod. Thanks to its high-impact-frequency feature, top hammer drilling offers high speed and high efficiency.<\/p>\n\n\n\n

The selection of hammer size is largely determined<\/h2>\n\n\n\n

The hole diameter and type of rock formation. The optimum blasthole range for DTH drilling is 3 \u00bd to 10 in. Smaller holes are typically drilled with a top hammer rather than a DTH hammer, and larger holes generally use the rotary drilling technique, mainly with the focus on hole straightness.<\/p>\n\n\n\n

As a general rule, the smallest hole diameter a DTH hammer can drill is its nominal size. A 4-in. hammer is optimally designed to drill a 4-in. hole. The closer the hole diameter is to the hammer\u2019s diameter, the more restricted the hole\u2019s evacuating airflow is. Drilling holes at the nominal size leaves adequate space for cuttings to evacuate the hole up the annulus between the hammer and drill pipe diameters and the internal diameter of the hole\u2019s wall.<\/p>\n\n\n\n

The maximum bit size for production<\/h2>\n\n\n\n

The maximum bit size for production drilling is the nominal hammer diameter plus 1 in. For instance, a 4-in. hammer\u2019s maximum bit size is regarded to be 5 in. in diameter.<\/p>\n\n\n\n

Ame Drill’s drilling tools is designed to suit drilling duties in various scenarios, including tunneling, construction, mining, quarrying, etc., with different types; drilling works on both soft and hard rocks can be performed perfectly. The Ame Drill top hammer drilling tools series includes drilling bits, coupling sleeves & shank adapters (striking bars). The Ame Drill DTH hammer tools include DTH hammers, DTH bits, DTH pipes, adaptors, overburden casing drilling systems.<\/p>\n\n\n\n
