The Lerin Tools LT-GTB-6 is a 6mm ceramic tile and glass drill bit with a tungsten carbide four-cutter tip and a 1/4 inch hex shank. The LT-GTB-6 cuts fixing holes in glazed ceramic tile, porcelain, glass and mirror. The hex shank seats in a standard drill chuck and locks into quick-change bit holders.
Drilling into a finished tile with a masonry bit is a quick way to fracture the surface and repeat the installation. Glazed ceramic is hard and brittle, so a percussion tip skates across the glazing before splitting the tile underneath. The tungsten carbide four-cutter tip scores through the glazed surface and holds the marked position from the first rotation. Bathroom and kitchen jobs call for a 6mm diameter on standard wall plug fixings, which covers most anchoring work on tiled surfaces.
Tilers and bathroom installers carry a 6mm diameter because towel rails, mirror brackets and shower screen fixings normally take plugs at that dimension. The 1/4 inch hex shank engages a quick-change holder, so the bit exchanges between holes without adjusting the chuck. Ground flutes evacuate dust from the hole, holding a cooler cutting temperature through dense porcelain. A clean hole on the first attempt avoids the expense of a replacement tile and a second visit to site.
The Lerin Tools LT-GTB-6 is cut for ceramic tile, porcelain, glass and mirror, so it is not intended for masonry, brick, concrete, timber or metal. Tile and glass drilling runs on rotary action, so this bit is not a hammer or impact bit. Percussion loads the carbide against a brittle surface and puts the tile at risk.
(LT-GTB-6)
The LT-GTB-6 has a 1/4 inch hex shank, which seats flat in a standard three-jaw drill chuck and locks into quick-change bit holders. Any corded or cordless drill with a keyless chuck will take it. Run the drill in rotary mode, not hammer mode.
A masonry bit uses a chisel tip designed for percussion drilling into brick and concrete. A tile bit cuts by scoring, so the tungsten carbide tip works its way through the glaze under rotary action alone. Four cutting edges spread that scoring action and stop the tip wandering across a glazed face.
The LT-GTB-6 is rated for ceramic tile, porcelain, glass and mirror. That covers glazed wall tile, dense vitrified floor tile, glass splashbacks and mirror sheet. Masonry, concrete, timber and metal sit outside its scope and call for a bit made for those materials.
Hammer action is not used for tile or glass. The carbide tip scores through the glaze under rotary drilling, and percussion drives the tip into a brittle surface that can crack. Set the drill to rotary mode, start slowly, and let the tip bite before increasing pressure.
Start the drill at low speed with steady pressure until the carbide tip scores through the glaze and forms a seat. A strip of masking tape over the mark gives the tip something to grip on a slick glazed face. Increase speed once the tip is biting.
Ceramic tile bits are ground for scoring glazed and brittle surfaces, not for percussion drilling into masonry. Using one on brick or concrete blunts the carbide quickly and gives a poor hole. A masonry bit run in a hammer drill is the correct tool for those materials.
