There is no cookie-cutter approach to selecting the right machine for a concrete drilling job. A number of factors come into play, including working conditions, drill weight, number of holes needed and more. With the following quick recommendations, you’ll soon be ready for concrete drilling with the right machine for the job.
1. Look at Gang Options
First, calculate how many holes you will need to drill. A single-gang drill is ideal for jobs ranging from several hundred to a few thousand holes. When a project moves up into the ballpark of 5,000 to 10,000 holes, a two-gang drill may be more appropriate. Looking at an even bigger job than that? Check out larger, multigang concrete drilling machine models, and consider using multiple drills to quickly achieve deadlines.
2. Consider ROI
There is a common misconception that a five-gang drill is going to be faster and more productive than a single-gang drill, but it could be overkill and more inefficient. Of course, high productivity is always a good thing, but it isn’t cost-effective to purchase a more expensive multi-gang unit when a single-gang drill is capable of doing the job to specifications and production requirements.
3. Let in Some Air
Typically when it comes to drilling, each gang operates independently and requires a certain cubic feet per minute (CFM) from the air compressor. As the amount of gangs increases, so does the air requirement. Always make sure your air compressor meets your drill’s CFM requirements for assured productivity.
By drilling into these details, you’ll find that bigger isn’t always better, less could be more and working smarter, not harder, goes a long way.
