Advantages of carbide drills:

(1) Good rigidity, high strength, easy to obtain high drilling accuracy.

(2) Can be used for drilling of more complicated materials, and higher cutting speed can be selected.

(3) Effectively reduce chipping and have good abrasion resistance.

(4) Multi-layered geometric cutting end edge improves chip removal performance and keeps small cutting resistance.

(5) In addition to the commonly used right-angle shanks, there are a variety of shank types, which are suitable for a variety of rigs and drilling machines.

(6) Compared with indexable blade drills, the overall hard alloy drill can be ground 7 to 10 times.

Disadvantages of cemented carbide drills: To grind well, it is easy to break the edge if the grinding is not good. The two main cutting edges are equal in height and angle.

These are the advantages and disadvantages of carbide drills.
