Annular cutter (also called core drill or broach cutter) is high-efficient drilling cutter with Multi-edge rail cutter. The diameter of the cutter ranges from 12mm-150mm. The product is mainly used to process the drilling hole, such as steel structure project, rail traffic, bridging, shipbuilding, machine manufacture and other hole processing fields. The hole drilling performance of annular cutter is much better than the traditional twist drill. The annular cutter possesses high-efficient drilling performance and labor-saving character.
Main characteristics of annular cutter (core drill):
1. Annular cutting, improving efficiency for multiple times than general twist drill;
2. When matching magnetic seat drill, it could conduct multi-direction drilling from front, side and top of the processed workpiece, and the drilling will not be restrained by auxiliary equipment, it is portable and convenient;
Features and highlights:
1. Possessing all the shank types, and being suitable for all the magnet drilling machines worldwide; completed sizes, max. Diameter of 150mm for standard series and max.cut depth of 150mm; max.Diameter of 200mm for customized series and max.cut depth of 200mm;
2. Employing corresponding technology support schemes for different processing demands (circular tube and laminated cutting);
3. Employing base materials with excellent intensity and tenacity, as well as special heat treatment process;
4. Employing long-short groove design scheme based on different cutting depth; Gradually-open spiral groove structure, the chip removal is smooth and the drilling is stable;
5. Automatic CNC machine tool processing, with consistent and stable quality;
6. Employing imported high-performance carbide blade with ultrafine particle and ultra-high hardness, ensuring service life;
