Understanding Features Of Rock Drilling Reamer

By Michael Barnes


While ground type is an important aspect to consider, drill experts factor in downtime, costs, and timeframe. To achieve the best results in a time and cost efficient manner, experts use reamers. With the right rock drilling reamer, digging small, medium or large holes while maximizing tooling costs and reducing downtime is possible. The most important aspect to have in mind is the diameter size. It should be 1.5 times bigger than that of the pipe to be fitted inside the hole.

Understanding the different types of ground you want to drill through is the first step to choosing a reamer that guarantees excellent results. People drill holes in mixed ground which is a combination of sand, hard rock and clay, sand soil, clay and rock ground. While it is important to define the ground you want to drill, there is no unique rotary precision cutting tool for a specific ground type. Here is a brief guide about the different cutting equipment operators utilize.

Digging a hole through the sandy ground that is water charged is challenging. The hole is likely to collapse when the tool passes through. That is why drill operators require compaction reamer which depends highly on bentonite filter cake to push digging fluid inside a hole. The digging fluid provides support to prevent the hole from collapsing.

Compaction reamers are cone-shaped, meaning they increase in size which helps open up holes. With a compaction cutting tool, it is easy to push digging fluids into the ground supporting the drilled hole to prevent collapse. This type is designed with flutes which allow the flow of drilling fluids and cuttings.

Selecting a suitable cutter can be difficult if you plan to use compaction fluted type reamers. To avoid wrong choices, consider the type of materials used to create a rotary precision cutter. The right one is made of solid material which is heavy to transport but cost-effective when it comes to repairs and maintenance. Other fluted reamers are designed out of cast materials or fabricated.

Apart from being cone-shaped or fluted, the best compaction rotary precision cutter is designed with carbide teeth and built-in swivels. Carbide teeth help but through different ground types allowing the flow of fluids. This makes compaction reamer tools ideal for drilling variety soils. The built-in swivels do not only prevent pipes from sticking in mud, they help drill operators pull back without the use of jack tools in case of an emergency.

If you are planning to drill holes in clay ground, the mixing tool is highly recommended. It breaks up soil particles and allows mixing of drilling fluids inside the ground. When clay and water mix clumps are formed which may cause clogs inside holes blocking flow of cuttings outside the hole. Mixing reamers such as a fly cutter, beaver tail and ripped reamers help the mixing action which breaks down ground particles to allow smooth flow of cuttings outside the hole.

Achieving the best results using a mixing reamer is easy if you factor in the fluid pumping action. Each mixing rotary cutter comes with a backward-angled mud jet which forces fluids outside drilled holes. This can only be achieved if the cutting blades are adjusted to work as boat propellers. With this few tips, it is easy to choose the right reamers to get pleasing results.
