A drill bit used for machining special-shaped holes
Bit size data: Basic size: Because the forming tool is a non-standard tool, so generally according to the customer to draw or workpiece map to design and custom
Product advantage
Can complete multiple hole processing, can also include some circular surface, can replace 2 or more types of drill or milling cutter
Processing case
Workpiece material hardness: HB200~250
As shown in the figure, the step and inner and outer arc surface of a set of tool handle holes are processed in one time, which is more than 10 times the efficiency of ordinary drill bit
Product advantages
High machining efficiency and good positioning accuracy compared to standard drill bits, especially when one hole has multiple inside or outside steps
If you have internal cold, you can also process some formed deep holes, although the tool cost increases, but the total cost of processing is reduced
Forming hole in addition to drill forming processing, there are also some reaming processing forming, or forming milling cutter, forming broach, etc
