HSS]: Delivers noticeably cleaner holes and cuts with far greater ease than typical step bits. Generally, M2 contains 50% more Tungsten and 150% more Molybdenum, both essential elements for enhanced durability. Additional vacuum heat treatment and nitride surface hardening further boost its performance.
[Non-stop]: Polished steps and clear size markings let you see the target hole size while drilling, so there is no need to pause mid-drill to check. This saves you time and reduces hassle. [Easier | Faster |
