High-quality material: 6542 HSS hard alloy head, which can prevent the drill from cracking. The twist drill bit set is made of a hard and durable alloy with a longer service life.
Unique design: U-shaped groove design can quickly remove drill chips, and the non-slip triangular handle can firmly fix the drill bit in the power drill.
Widely used: The sturdy tungsten carbide tip of the spear tip can easily penetrate various materials, such as tiles, concrete, brick, glass, plastic and wood, etc., and reduce cracking.
There are 4 different sizes of drill sets: 2 x 6mm (1/4"), 1 x 8mm (5/16"), 1 x 10mm (3/8"), 1 x 12mm (1/2").
Tip: When drilling hard materials (such as glass, porcelain floor tiles, marble, granite, etc.), please lubricate with water.
