Set of 12 carbide masonry drill bits for concrete, stone, tile, brick, ceramic, glass, sheet metal, plastic and wood, 6 mm quick-change hexagonal shank, sizes 3 mm, 4 mm, 5 mm.

Versatility - Our concrete drill bits include: 1 x 3 mm, 1 x 4 mm, 2 x 5 mm, 4 x 6 mm, 2 x 8 mm, 1 x 10 mm, and 1 x 12 mm to meet a variety of needs.

Hex Shank - All 11 drill bits feature the most common 6 mm hex shank, providing an ideal solution for drilling with hammer drills and impact drivers/drivers.

Fast and Durable - The large-capacity 11-piece carbide impact drill bit set uses sharp carbide tips to drill through masonry materials faster and extend the life of concrete.

Large Capacity - Ideal for drilling concrete, walls, bricks, ceramics, wood, glass, tiles, stainless steel, and more.

The use of water or coolant is strongly recommended for drilling harder materials. Efficient - These drill bits start faster and reduce walking in concrete, brick, and block; the wide-flute design allows for rapid dust removal and reduces heat.
