INSTALLATION & USE

How to Use the Relton GRT-8-6

  1. Insert the GRT-8-6 bit into your drill chuck and tighten securely. For hard metal drilling, mount your drill motor to a drill press for stability and control.
  2. Mark your drilling location on tile, granite, masonry, or other material. Begin drilling at a slow speed to establish the hole, then increase to full speed as the serrated carbide tip engages.
  3. Apply steady, moderate pressure and allow the Groo-V Tip to do the work. The serrated carbide edge will cut faster than standard bits without requiring excessive force.
  4. For through-holes in tile or granite, reduce pressure as you near breakthrough to prevent chipping on the exit side.
COMPATIBILITY

Recommended Applications

The Relton GRT-8-6 Groo-V Tip bit is ideal for water filtration installers who need to drill mounting holes through tile backsplashes, granite countertops, concrete walls, or masonry for RO system installations. The 1/2" diameter accommodates standard supply line penetrations and mounting hardware. Compatible with any standard drill chuck in percussion or rotary-only mode, making it versatile across cordless drills, hammer drills, and drill press setups.

🔧 Pro Tip: When drilling through tile or granite countertops for water line penetrations, place painter's tape over the drill site to prevent the bit from walking during initial contact and to reduce surface chipping.
