About this item

·【COMPREHENSIVE 12-PIECE DRILLING SET】Four diamond-coated bits (1/4" to 1/2"), four masonry bits (1/4" to 1/2"), three driver bits (Torx, Hex, Phillips), and a durable storage case for glass, tile, concrete, and granite applications.

·【ADVANCED DIAMOND GRIT TECHNOLOGY】Vacuum-brazed diamond particles provide enhanced cutting efficiency on hard surfaces, resisting heat buildup during extended drilling operations.

·【OPTIMIZED DEBRIS CLEARANCE SYSTEM】Wide-flute design minimizes material accumulation during drilling, reducing friction and preventing surface damage on brittle materials.

·【RAPID HEX SHANK COMPATIBILITY】1/4-inch quick-change shank fits standard power drills for immediate bit transitions without tool adjustments.

·【PRECISION ENGINEERING FOR SLICK】Laser-cut tip geometry maintains drilling accuracy on smooth tiles and glass, preventing bit slippage at hole initiation.
