Helicalgeotechnical design/build

Helical Drilling is a geotechnical design/build contractor focused on providing innovative, efficient, adaptable geotechnical engineering and ground construction solutions to general contractors, owners and engineers throughout the Northeastern United States. For almost 30 years, Helical has specialized in Geopier® Rammed Aggregate Pier® ground improvement, earth retention, grouting, deep foundations and piles, underpinning and additional geotechnical construction solutions. Comprised of geotechnical engineers, construction managers, and field crews under one roof, HELICAL is the premier turnkey firm for a multitude of geotechnical design-build solutions.

Whatever the reason for enlarging a hole though, it has traditionally been difficult to do accurately on site and away from static, precision milling and drilling machines, especially in hard materials such as steel.

Specially designed cutting geometry allows the tool to be used in an Impact wrench or a Magnet drill. When used in an Impact wrench it is secured into a special adapter meaning the tool is easier to control, apply correct feed rate, and withdraw from the finished hole, enhancing tool life. This reamer will also fit into a standard Weldon magnet drill arbor.

Many building and construction professionals will testify. A job on-site or in the workshop can be going fine until a small problem like a misaligned hole, a poorly drilled hole, or a connection hole that is too small, can put a very expensive spanner in the works.

The tapered design allows the narrow end of the ImpactaCut reamer to be entered into the existing hole and accurately centred.

VersaDrive reamers are the perfect hole alignment and enlarging tool for metalworkers & steel erectors for keeping the job moving when a hole is misaligned or the incorrect size for the fixing.

It was a desire to provide a solution to these challenges that led us to create two brand new products - Enter the VersaDrive and ImpactaMag range of construction and fabrication reamers.

The process by which this is done is called Reaming and differs from traditional drilling as it requires an existing hole, or holes, as a starting point. A reamer cannot create a hole from scratch, only increase the size of current holes.

The correct tool for the job will depend on the drive tool you are able to use, the size of the final hole required and the material you are reaming.

With it’s Weldon shank the ImpactaMag reamer will fit directly into a standard 19.05mm arbor whilst it’s construction makes it perfect to tackle thicker materials, over 20mm in depth.

If you are using a magnet drill without an adapter, require a hole size between 26-39mm or have material greater than 20mm thick then the ImpactaMag Reamer would be the recommended option.

Combining our pioneering, impact rated and now patented VersaDrive® system with the latest generation of high-torque cordless power tools has created a revolutionary level of drilling speed & performance, never before possible with portable tools.

There are many reasons why holes need to be modified after they have been created – most commonly these can include specification changes, a change in the type of fixings to be used, or even simply a measurement mistake at some stage of the process.

Featuring a specially designed 6 flute cutting geometry and Titanium coating, VersaDrive™ Reamers are fully Impact rated and perform fastest when used with an Impact wrench providing ultimate cutting performance with virtually no powertool kickback.

Below you will find a step-by-step guide to reaming along with technical recommendations, best practice advice and information on the range of HMT reamers available and the best situations in which to use them.

VersaDrive Reamers have a patented non-slip, Hex shank suitable for use in any standard 1/2” drill chuck for cordless or pistol drills or used with a VersaDrive Rapid Lock adapter for use in a wide range of powertools such as Magnetic Drills.

VersaDrive reamers can also be used with cordless drills and magnet drills or pillar drills so for applications requiring holes up to 26mm diameter in materials up to 20mm thick VersaDrive reamers are still perfect for the task.

When using a portable power tool like an Impact Driver or Impact Wrench and the final hole size required is below 26mm the VersaDrive Impact Reamer would be the recommended option. This tool quickly and easily fits the VersaDrive range of quick-change, rapid-lock adapters and can be used to enlarge a hole in materials up to 20mm thick.
