Is this the right tool for the job?

Best For:

  • MEP and coring subs doing daily slab and wall penetrations in concrete
  • One- or two-person crews needing clean, controlled wet coring
  • Large-diameter sleeve and conduit holes on ongoing commercial work

Not Ideal For:

  • Sites with weak power, long light cords, or small generators
  • Dry-only jobs or areas where water/slurry control isn't allowed
  • Fast 1-2 in. holes; a handheld core drill or rotary hammer is quicker

Why Pros choose this tool:

  • Rig‑mounted base and carriage → stable, plumb coring → safer runs and sleeve‑ready holes with less rework
  • Single‑phase electric drive → consistent torque under load → predictable pace with fewer stalls and glazing
  • Large‑diameter coring capacity → one-pass holes for big sleeves → no step‑coring, faster through‑slab penetrations

Variant Guidance: Most pick 18" for general coring
