When you need a 4-1/8" hole through porcelain, granite or stone, there's not much room for error.
Meet The Rook 105mm Vacuum-Brazed Diamond Hole Saw.
Built for large-diameter openings and demanding materials, The Rook combines an aggressive vacuum-brazed diamond cutting edge with a heavy-duty steel body to make fast, controlled holes where smaller bits simply can't do the job.
No drill arbor.
No complicated setup.
Its 5/8"-11 thread mounts directly onto a compatible angle grinder.
THREAD IT ON. MAKE THE HOLE. CHECKMATE.
105mm / 4-1/8" Diameter — Built for large plumbing, drain and penetration openings.
Vacuum-Brazed Diamond — Aggressive diamond cutting surface designed for hard tile and stone.
5/8"-11 Direct Thread — Screws directly onto a compatible standard angle grinder spindle.
Fast Material Removal — Designed to cut large openings efficiently through dense materials.
Clean, Controlled Holes — Helps minimize chipping around the finished opening when used properly.
Diamond Side Protection — Diamond coverage extends beyond the cutting edge to assist during the cut.
Wet or Dry Cutting — Can be used wet or dry, although water is highly recommended to improve cooling and extend bit life.
Professional Size. Professional Performance. — Built for installers who need serious hole-cutting capability on the job.
Because sometimes the hole isn't small.
The 105mm Rook is an ideal size for larger penetrations encountered during professional tile and stone installation.
Think:
Toilet drain openings
Large plumbing penetrations
Dryer vent openings
Large pipe penetrations
Mechanical openings
Countertop penetrations
Specialized fixture installations
Other large-diameter cutouts
Instead of pie-cutting the opening with a grinder and trying to clean it up afterward, make the hole with the tool designed to make the hole.
The Rook is built to tackle:
Porcelain tile
Ceramic tile
Granite
Marble
Engineered stone
Quartz surfaces
Compatible natural stone
Not recommended for concrete, metal or wood.
Hard porcelain and stone destroy cheap abrasives.
The Rook uses vacuum-brazed diamond technology, bonding exposed diamond abrasive to the cutting surface for aggressive material removal through dense tile and stone.
The result is a hole saw designed around the materials professional tile installers actually encounter.
No drill chuck.
No separate arbor.
The Rook features a standard 5/8"-11 threaded connection designed to mount directly onto a compatible angle grinder.
Thread it on.
Position your cut.
Get to work.
The Rook can be used wet or dry, but if you want to get the most life possible out of your diamond tooling:
USE WATER.
Cooling the bit during cutting helps control heat and can significantly improve tool life.
Especially on a 105mm bit removing this much material, proper cooling matters.
