The Precision of Aligned Diamonds
"Dry drilling is a battle against heat and friction. Standard bits with randomly dropped diamonds often seize or overheat. At Supreme Diamond Tools, we integrated Arix Patterned Technology into our dry core bits to ensure that a perfectly positioned diamond is always engaging the material. This reduces friction, maximizes airflow, and allows HVAC and plumbing professionals to bore through masonry in half the time without a drop of water."
— The Supreme Diamond Engineering Team
The Supreme Grade Arix Dry Core Bit represents the pinnacle of dry drilling technology. Specifically engineered for handheld operation, these bits combine the safety of industrial laser welding with the unmatched speed of aligned diamond segments. Designed for clean, fast results in soft brick and masonry, this series is the essential tool for professional contractors focused on remodeling and utility installations.
| Diameter | Dimensions (Dia x L x H) | Thread Arbor | Segment Tech |
|---|---|---|---|
| 2" - 2.5" | X" x 9" x 10mm | 5/8"-11 | Arix Aligned |
| 3" - 4.5" | X" x 9" x 10mm | 5/8"-11 | Arix Aligned |
| 5" - 6" | X" x 9" x 10mm | 5/8"-11 | Arix Aligned |
MATERIAL LIMITATIONS: This Arix series is a specialist tool for soft brick, masonry, and concrete block. To maintain the integrity of the laser-welded segments, do not use this bit on solid poured concrete or reinforced stone. When drilling, use a steady "in-and-out" motion to help the laser-cut slots clear the dust from the hole—this prevents the bit from binding and significantly extends the life of the Arix segments.

Q: Why is Arix technology better for dry drilling?
A: In dry drilling, heat is the enemy. Random diamonds create uneven friction. Arix ensures diamonds are spaced perfectly, which creates "micro-channels" for air to pass through, keeping the bit cooler and sharper.
Q: Can I use this with a standard hammer drill?
A: It is recommended for use with rotary-only handheld core drills. Using a hammer/impact mode can fracture the laser welds or damage the Arix segments.

I recently purchased the 3-inch Supreme Diamond Tools dry drill core bit, and I'm very impressed with its performance. I primarily used it for drilling into concrete blocks for a remodeling project, and it cut through them with ease. The drilling speed was noticeably faster than my previous core bit, and the cuts were clean and smooth. I appreciated that I didn't need to use water, which made the job much less messy. The 5/8"-11 threaded arbor fit perfectly on my drill. So far, the bit seems very durable, and I expect it will last a long time. I would definitely recommend this core bit to other contractors and builders looking for a high-quality, reliable dry drilling solution.
The Arix segments really help keep the drilling speed up. I got smooth holes in block without much effort. A bit pricey, but it lasts longer than cheap core bits.
I used the 3" bit on a brick veneer project and it drilled through fast and clean. No binding, no overheating. Exactly what I needed for dry drilling.
