HUSQVARNA CONSTRUCTION SKU: 967910303 Copied!

Is this the right tool for the job?

Best For:

  • MEP, fire, and GC crews making pipe/conduit sleeves in concrete daily
  • One-tech service work: fast setup, wet coring through walls and slabs
  • Two-person teams for big diameters or overhead using a mounted rig

Not Ideal For:

  • Dry-only work in reinforced concrete; plan water and slurry management
  • Hand-held on large diameters or overhead—use a stand and proper rigging
  • Sites with weak power or long cord runs that cause trips and slow drilling

Why Pros choose this tool:

  • Integrated water feed → controls silica and slurry at source → cleaner interiors and easier compliance
  • LED load meter + overload protection → keeps bit in the sweet spot → faster cores and longer bit life
  • Mains power + high‑torque gearing → holds speed in reinforced (with right bit) → predictable hole times, fewer stalls
