[Special Note]:
HRC (high breaking capacity);
Our products are divided into two hardnesses, HRC62 and HRC67.
The first material is HRC62 (marked as A-B-C-D on the picture), drilled plastic, wood, and aluminum are all right.
But if you need to drill steel or iron plates, or want a longer tool life, we recommend that you choose the second material HRC67 (E-F-G-H-I is indicated on the picture).
