Compatible Tools & Installation Fit Check
- Rotary Hammer Drills: SDS-Plus and SDS-Max cordless hammer drills for masonry and reinforced concrete anchor drilling.
- Impact Demolition Hammers: Cordless chipping hammers and tile scrapers with high mechanical shock.
- Fit Check: Inspect battery slide guide rails for debris, and ensure locking latch engages with an audible click before operation.
First-Party Structural Engineering Evidence
- Heavy-Gauge Spot Welded Interconnects: 0.2mm pure nickel strips with reinforced cross-welds prevent weld-joint fatigue under continuous vibration.
- Conformal Coated BMS: Moisture, dust, and anti-vibration potting compound applied to the internal PCB protects sensitive MOSFETs from mechanical fracture.

Frequently Asked Questions (FAQ)
Q: Will continuous concrete hammering crack the battery terminals?
A: No. We utilize phosphor bronze high-spring-rate terminal clips reinforced with fiberglass ribs to maintain electrical contact under continuous impact.
