Micro-impact drilling is one of the most efficient dry drilling methods available today. When paired with properly designed core bits, it delivers faster penetration, cleaner holes, and longer bit life compared to conventional dry drilling — all without water.
How Micro-Impact Works
Micro-impact adds high-frequency, low-amplitude impulses to the rotation of the core bit. Unlike hammer drilling, the impulses are small and frequent — improving penetration in dense concrete without the aggressive percussion that can crack surrounding material or damage finished surfaces.
Key Advantages
- 3–5× faster than conventional dry drilling
- Cleaner job site conditions — no water, no slurry
- Reduced bit binding and tool load
- Longer bit life when using compatible RS-TX core bits
- Ideal for finished interiors and occupied buildings
Compatible Core Bits
Micro-impact mode requires specially designed bits. Standard dry core bits will wear prematurely or fail. Browse Distar diamond core drill bits for micro-impact and dry drilling applications.
