Explore the reaming capabilities of the Vermeer D220x500 S3 horizontal directional drill

An ideal balance of drill rotational torque and spindle speed

The new Vermeer D220x500 S3 horizontal directional drill (HDD) lets you choose your own drilling experience thanks to an incredible number of versatile options that allow you to configure it for your specific needs. To learn more on that, visit one of the following links:

Today, though, you’ll read more about a feature of the Vermeer D220x500 S3 HDD that can help your crew work more efficiently in a range of soil conditions: its hole-opening capabilities.

Torque vs. speed

The number of reamer passes, and how long each pass takes, can significantly impact the number of days your crews are working on the bore. Every pass adds up in hours, wages, and expenses — this is why your drill’s rotational torque and spindle speeds are so important. Having ample rotational torque can allow you to cut more material on every reamer pass, which helps reduce the total number of passes made. In sticky clays, or when using some types for reamers, you want fast spindle speeds to help reduce the time it takes to make a reamer pass and help break down the material.

With the customizable Vermeer D220x500 S3, you get to prioritize what’s more important — torque or speed.

Two gearbox configuration options

Vermeer designed the D220x500 S3 with two gearbox configuration options. The D220x500 S3 can be configured to produce a class-leading 52,600 ft-lb (71,318.1 Nm) of rotational torque and a spindle speed of 36 rpm for working in challenging grounds. For less adverse conditions, choose the configuration that prioritizes spindle rotational speed — 97 rpm and 30,000 ft-lb of (40,675 Nm) rotational torque.

Downhole flow

While rotational torque and spindle speed play an essential role in an HDD’s hole-opening ability, downhole fluid flow is also a factor. Drilling fluid helps break up and clear ground material, lubricate and cool tooling, and maintain the integrity of the bore path. 

The D220x500 S3 excels in this area, too. The drill’s water course system has four 1.5-inch (3.8-cm) mudlines and a 3-inch (7.6-cm) head shaft to allow high fluid volumes to be pumped downhole. Combining the D220x500 S3 drill’s high rotary torque and fluid pressure produces optimized drilling and reaming performance challenging ground conditions.

Outstanding performance

The Vermeer D220x500 S3 drill’s impressive hole-opening ability, combined with its other customizable features, lets you match your drill experience to your specific needs.
