What Is a Drill Plate?
There are two main types of multi-blade steel plate drills: one is high-speed steel plate drills, and the other is hard alloy steel plate drills. High-speed steel steel plate drills have good stability and regrindability, and are currently the main application series. Carbide steel plate drills have high cutting speed and can complete drilling operations for complex materials.

- Hollow drill (also known as core drill, steel plate drill, hole drill), its standard name is multi-blade steel drill. It adopts the form of multi-blade ring cutting, which uses the drill to cut only the outer diameter ring portion of the hole, and does not cut the middle portion, thereby greatly improving the drilling efficiency. Combined with a magnetic drill, it can realize drilling at any time on site Compared with ordinary twist drills, the efficiency is higher and the cutting is lighter. The drilling diameter is from 12mm to 150mm, and the depth is 25mm, 35mm, 50mm, 75mm, 100mm, 150mm, 200mm, etc.
