Product Tags

There is no burr in the hole, and the hole is drilled many times, and the hole is still intact;
Strong cutting ability, sharp and durable, adopting forward and backward inclined tooth profile is more suitable for cutting metal plates;

When drilling, the center drill penetrates the material to be processed first, as the axis, the drilling is more stable; the triangular anti-skid blasting prevents slipping during the drilling, suitable for hand electric drills/bench drills/magnetic drills and other equipment;

2. Matters needing attention: When you first start drilling, the hole opener should slowly touch the object being drilled, and cannot hit the workpiece. The speed should be low (the larger the hole opener, the lower the speed). If possible, add coolant or water. Please pay attention to slow down the feed speed when you are about to drill through.

4. In order to prevent chipping, please don’t let the blade of the hole opener and the cutting material immediately violently collide.
5. It is necessary to add water or coolant to cool down, otherwise there is a risk of burning the drill bit
6. If abnormal vibration or noise occurs during cutting, please reduce the spindle speed and cutting feed rate until the situation improves.
7. Earplugs should be plugged in during long-term operation, as well as the influence of noise.
