SUBFLOOR PREPARATION DRILL SMARTER
Accurate concrete moisture testing is a critical step in subfloor preparation before installing floorcoverings. Here, Jason Spangler, Wagner Meter’s vice president of sales discusses how vacuum drill bits improve RH testing accuracy and efficiency.
Having the right drill bit could change everything. Drill bits designed for speed, ease of use, and durability go a long way in saving you time and effort. But what if there was a tool that didn’t just make the drilling easier, but the hole cleanup as well?
WHAT ARE VACUUM DRILL BITS?
Vacuum drill bits can be connected to a shop vacuum so you can clean dust as you drill into concrete. Here’s how it works. The shaft of the bit is hollow, so instead of using spiral blades to push debris upward, the suction from the vacuum pulls the dust up through the shaft, eliminating the need for cleanup.
Being able to drill and clean in the same step is a game changer. And better hole quality leads to more efficient and accurate moisture testing.
WHY HOLE QUALITY MATTERS IN RH TESTING
You might not think twice about drilling holes for your RH sensors. Though it isn’t very difficult, there are some things you’ll want to keep in mind for accurate RH moisture testing – hole size and silica dust.
First, let’s look at why hole size matters. The holes you drill are created for your RH sensors. Unevenly shaped holes, or holes that don’t meet your RH sensor’s hole diameter requirements, prevent proper sensor anchoring, which can compromise the accuracy of your testing results. So, a random drill is not going to work – you need one designed for precise hole measurements for your RH sensors.
Another thing you’ll need to think about is the silica dust that’s naturally created while drilling. On top of being a safety hazard, this dust can mess up RH readings if it’s not thoroughly vacuumed out.
Most of the time, flooring installers have to use a small brush to manually loosen up debris before inserting a vacuum attachment into the hole to remove any remaining dust. If you’re working on a big job where you need to drill 50-70 holes, something as seemingly-simple as dust cleanup can become a very time- consuming process. Fortunately, high-quality vacuum drill bits can make all the difference.
WHY WE RECOMMEND THE HILTI TE-CD CONCRETE DRILL BIT
If you’re looking for a vacuum drill bit, we recommend the Hilti TE-CD Concrete Drill Bit because it can save you a significant
•
amount of time and effort, especially on large jobs where you’ll be using a lot of RH sensors.
THE HILTI TE-CD CONCRETE DRILL BIT:
• Maintains precise hole diameter/size: It creates consistent and appropriately-sized holes for Rapid RH sensors to anchor properly.
• Doesn’t snag as much as other drill bits. •
Is fast and durable: The carbide tips are strong and sharp, making for quick and efficient drilling. One customer, Andrew Campbell, had this to say about the TE-CD: “This is my fourth one. This bit cuts through concrete like butter through the first 100 or so holes. I have been able to use one of these bits for approximately 400 holes.”
• Makes hole-cleaning effortless: Its hollow-drill design allows you to vacuum as you drill. There’s no question that you’ll save considerable time on dust cleanup.
Is a safer way to deal with dust: By sucking up silica dust as you go along, you won’t have to worry about accidentally breathing in large amounts of it.
With a vacuum drill bit like the TE-CD, you can skip the hassle and mess of drilling holes and set yourself up for consistent, accurate RH readings.
