• Highlight: Threaded 5/8-11 right-angle adapter from MK Diamond that mates Sawtec ZEK grinding discs to standard right-angle grinder spindles, eliminating shaft-mismatch downtime on the jobsite.
• Best For: Stone fabricators and tile installers running ZEK-pattern grinding discs on right-angle grinders during edge prep, joint relief, and small bevel work.
• Expert Note: The 5/8-11 thread is the dominant right-angle grinder standard in North America, so a single ZEK adapter typically covers an entire fleet of grinders rather than requiring brand-specific arbors.
