✿【High quality alloy material】
1. Carbide cutter head material has stronger hardness.
2. Carbide drill bits are durable and can keep sharp for longer than typical steel drill bits.
1. The drill has smooth hole opening, no edge breaking, no tremor, easy positioning, and improved drilling speed.
✿【Spiral Torsion Shaft】
1. The spiral torsion shaft increases the cutting area and leaves a clean hole.
2. Combining chip removal and drill, the pointed design is more convenient to use, save time, and can punch holes quickly.
✿【7 different sizes】
1. 4 different sizes: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm.
2, 4 different drill bit sizes will help to start from the smallest bit and continue to the required size for drilling.
1. The sturdy tungsten carbide tip with pointed design can easily penetrate various materials (porcelain tiles, glass, mirrors, plastic bricks and wood).
2. If you use a drill to drill concrete, brick walls and other hard materials (glass, porcelain floor tiles, marble or granite), please use water to lubricate.
