Helix Hellion Dry Core Diamond Bits — Water-Free Coring for Premium Installs

In high-end tile and panel work, drilling dense porcelain or ultra-compact surfaces is where the schedule stalls — standard bits glaze, stall, and crack the surface. The Helix Hellion Dry Core Bits are engineered to core cleanly and quickly without water, so you can tap holes for plumbing, electrical boxes, and accessory mounts without dragging trays and hoses into a finished space.

The dry-drill design keeps the work area clean, while the “H” cooling-port architecture pulls heat away and clears dust. Internal and external diamond brazing gives these bits the longevity and consistent cutting life premium installs demand. A 5/8″-11 female thread taps straight into the grinders and drills you already run.

Why Tile Pros Choose It

  • No water required — dry coring wherever water is impractical or messy
  • Made for dense materials — optimized for porcelain, UCS, and hard ceramic
  • Thread-ready fit — 5/8″-11 works with standard pro grinders and drills
  • Built to last — H cooling ports and dual diamond brazing extend life
  • Clean finish — controlled coring without the blowout standard bits cause
  • Flexible sizing — diameters to match fixtures, boxes, and penetrations
  • Finished-room friendly — no trays, no hoses, no cleanup circus

Pro tip: Start at a slight angle to set the rim, then bring the bit upright once it bites — it prevents skating on slick porcelain. Ease off the pressure as you break through to protect the back face of the tile.
