Review on Viking Drill Tool 58010 SP 18TDF by Sorithytep John

According to my experience, this drill bit was a complete disappointment. The only positive thing I can say is that it handled basic tasks somewhat decently. However it quickly became dull and ineffective on tougher materials. The worst part? It snapped in half halfway through a project, leaving me stranded without a backup. Save your money and invest in a higher quality drill bit..
