Montolit FAJ06 1/4" Diamond Drill Bit — The Everyday Anchor Hole, Done Clean

The 1/4" hole is the one you drill all day — anchors for shelving, grab bars, shower accessories, and mounting brackets. Drill it rough and you've got a chipped face and a weak anchor; drill it clean and the fixture sits tight and looks right. The Montolit FAJ06 puts a vacuum-brazed diamond crown on that everyday hole, biting hard through dense porcelain, natural stone, and glass and leaving crisp edges instead of blowout.

Run it wet or dry, on a drill or an angle grinder; the balanced body starts accurately and tracks straight. On dry work, a dip in M-PERFORMER cooling gel keeps it cutting cool, and the Diamond Countersink chamfers the finished hole so a mounted fixture doesn't crack it later.

Why Tile Pros Choose It

  • Clean everyday holes: Vacuum-brazed 1/4" crown for chip-free edges
  • Hard materials: Dense porcelain, natural stone, and glass
  • Wet or dry: Drill or grinder, whatever's in your hand
  • Tight anchors: Clean walls mean fasteners grip the way they should
  • Best for: Shelving and shower-accessory anchors, fasteners, and brackets
  • Earns its keep by Tuesday: It's the size you'll reach for more than any other

Pro tip: Start at a low angle to bite the glaze, then straighten up once seated. Ease off the pressure as you break through the back to avoid blowing out the exit side of the tile.
