Frequently asked questions
Common questions about ARTU from 3G Electric.
What materials are ARTU drill bit kits designed to drill?
ARTU drill bit kits are specifically designed for drilling porcelain tile, ceramic tile, and glass. The bits feature carbide tips and a starter geometry that helps prevent chipping and cracking on hard, brittle surfaces. They are not intended for use on metal, wood, or plastic, as the cutting edge and flute design are optimized for tile materials.
What sizes are available in the ARTU Porcelain Tile Starter drill bit kits?
ARTU Porcelain Tile Starter drill bit kits are available in five sizes: 5/32 in, 3/16 in, 1/4 in, 5/16 in, and 3/8 in drill bit diameters. Each kit includes a single bit with a shank diameter matching the bit size, and overall lengths range from 3 1/8 in to 5 5/16 in depending on the size. These sizes cover common pilot hole requirements for tile anchors and fasteners.
Can ARTU drill bits be used with a standard drill driver?
Yes, ARTU drill bits have shank diameters that match the bit size (e.g., a 1/4 in bit has a 1/4 in shank), making them compatible with standard drill chucks found on most drill drivers and rotary tools. The bits are designed for use at moderate speeds with light pressure to avoid overheating the carbide tip or cracking the tile.
Do ARTU drill bit kits include multiple bits or just one?
Each ARTU drill bit kit contains a single bit of a specific size. The kits are sold individually by size, not as multi-bit sets. This allows maintenance managers and procurement specialists to order only the exact diameter needed for their application, reducing inventory waste.
What is the advantage of a starter drill bit for porcelain tile?
A starter drill bit, like those from ARTU, has a specialized tip geometry that creates a small pilot hole without the bit wandering on the smooth, glazed surface of porcelain tile. This reduces the risk of chipping or cracking the tile, which is common when using standard twist drills. The starter hole can then be enlarged with a larger bit if needed.
