The technology used in portable drilling machines is relatively straightforward. But that doesn’t mean you shouldn’t take time to choose one carefully. If you understand how they’re built and what each component does, you’ll be in good shape to choose an appropriate machine that will give you many years of trouble free use across a diverse range of projects.

With this in mind, we’ve created an infographic guide to the Mirage HT50 drill, which is a heavy duty, high torque portable drilling machine used for general on-site metal drilling projects. Take a look at our infographic to discover how it works.

For a quick snapshot take a look the image below, or download in PDF format. Click here to download the diagram in PDF format.

The VHT series of machines has been designed for wellhead machining applications, such as when gate valves are seized. When this happens, one solution is to fit a new valve on top of the defective one and to machine a hole through the seized slab gate, allowing the product to flow through.

Spade drills used for heavy duty hole creation are very different to normal twist drills. They comprise of two parts and deliver several advantages for in-situ machinists and for manufacturers carrying out repeat production runs.

The main advantage is that a spade drill includes a replaceable cutting blade. This is secured in a fluted holder which can be conveniently replaced when it reaches the end of its usable life. There are many other advantages too, but also a few drawbacks to be aware of.

Removing seized bolts is a frustrating and time consuming process and is fraught with risks to both the machine operator and the components surrounding the bolts. By their very nature, flange joints in the oil, gas and power generation industries are tight, stubborn and difficult to dismantle. But with the right equipment the job can be carried out efficiently and safely.

Here we look at two very different methods of bolt removal and give an insight into the portable machine tools available to carry out the job.

The Casing Double Pin Drill

In our previous blog we told you about our band saw and how it performed during workshop trials. This time we take a look at the DDU1636 double drill unit which was also designed by the Mirage team for offshore decommissioning projects.

In 2012 the Mirage DDU was runner-up product at the World Oil Awards on the ‘Health, Safety, and Environment / Sustainable Development Offshore Award’ category.

The machine is mostly used for drilling lifting holes into casings, which can then be severed using a portable band saw and lifted out of position. The robust construction and carbide tipped cutters makes it an ideal tool for cutting through different materials as used in cemented casing strings.
