What KJ-2 and ZY bits can do, KJ-1 can do. And KJ-1 have the longest life of these three types.
The angle of conventional KJ-1 drill bits is also different from that of KJ-2 and ZY.
And for most shapes of bits, KJ-1 can be customized. So if you have other overall design requirements for the drill bit, KJ-1 can meet them. KJ-1 is more durable and it is suitable for mini size. Because of more tungsten carbide, KJ-1 can fit for many special work.
For which size out of 2.5-8, we also supply KJ-1 drill bits for solid carbide that the whole bit is carbide include shank.
KJ-1 Drill bits main work for MDF、chipboard、laminated and any other wood types.
And KJ-1 drill bits are made by 5-axis machining center, so these bits have best accuracy. If you have demand for holes’ accuracy, I think KJ-1 bits will be your best choice.
We also accept KJ-1 step drill bits’ customized requirements. Even for some models, KJ-1 is more affordable.
Many customers choose to use KJ-1 on the machining center, which can give full play to its functions.
If you have high standards in service life, product accuracy, processing and efficiency, I think KJ-1 drill bits will meet your needs.
