Choose Your Kit: Complete 5-Piece Set or Individual Bits: this listing offers two options:The 5-Piece Set: Contains two 1/4" bits, plus 5/16", 3/8", and 1/2" bits, packaged in a durable hard plastic case. This is the ideal starter kit for common tasks. 7 Individual Sizes: need a specific size? You can also purchase any of the seven most popular sizes separately: 1/8", 5/32", 3/16", 1/4", 5/16", 3/8", and 1/2"
Premium Tungsten Carbide Tip for Durability: features a hardened tungsten carbide tip, providing exceptional hardness and wear resistance. This allows for easy penetration and long-lasting performance in tough materials like concrete, brick, tile, marble, glass, wood, and plastic-truly a multi-purpose bit
Eccentric Tip & 4-Flute Design for Fast, Clean Starts: the eccentric (off-center) tip bites instantly on smooth, hard surfaces (like glass or glazed tile) to prevent wandering. Combined with the aggressive 4-flute serrated design, it delivers powerful cutting force and speed for faster, cleaner holes than standard twist drills
Deep Flute Design for Efficient Chip Removal: the optimized deep spiral flutes efficiently channel debris out of the hole during drilling. This prevents bit clogging and binding, reduces heat buildup, and ensures smoother, faster drilling with less effort
Secure Hex Shank for Universal Compatibility: the 1/4" hex shank with full anti-slip flats ensures a rock-solid, non-slip grip in any drill chuck. Safely compatible with cordless drills, drill drivers, hammer drills (use non-hammer mode for tile/glass), and bench drills
