The Dart 5 Piece Multi-Purpose Drill Bit Set (Mupset5H) is engineered for professional tradespeople and serious DIY enthusiasts who require a single, reliable solution for drilling into diverse materials including masonry, steel, wood, and tile. Its primary benefit is the 120-degree diamond-ground tungsten carbide tip, which offers exceptional hardness and longevity across varied surfaces; however, users should be aware that these bits perform best when used with controlled speed rather than high-impact modes to prevent premature dulling of the carbide edge.

No, these bits are designed for rotary drilling. Using them in hammer mode can damage the carbide tip.
The set includes 5.5mm, 6mm, and 7mm sizes (all 100mm long) and an 8mm size (120mm long).
These bits are designed for standard steel and cast iron; they are not intended for use on heat-treated or hardened steel.
While not strictly required for every tile type, using water as a coolant will significantly extend the life of the bit tip.
Yes, they are compatible with any standard drill chuck that accepts the shank sizes provided.
Use a center punch to mark the hole location, or start the hole at a low speed to create a pilot indentation.
Pull the bit out partially while the drill is still running to clear the accumulated debris from the flutes.
The bit tip may have overheated or dulled; check for damage and ensure you are not using hammer action.
Ensure these bits are used in a standard rotary drill chuck. While they are multi-purpose, they are not designed for the extreme mechanical shock of hammer-action drills; ensure your drill's impact mode is disabled. To maintain the life of your bits, store them in a dry environment to prevent corrosion. Periodically inspect the carbide tip for signs of chipping or dullness. If you are drilling into very hard materials, consider using a coolant or drilling at a slower speed to prevent the carbide tip from overheating, which can degrade the bond between the tip and the steel shank.
