RAY FOSTER - AG05 Variable-Speed Alloy Grinder with Automatic Spindle, 220V 50/60Hz

RAY FOSTER Model AG05 Variable-Speed Alloy Grinder — 220V

Variable-speed (up to 26,000 RPM) precision Grinder with fingertip control and 2.5″ external dust port (export configuration — ships from our Miami consolidation)

For over 85 years, RAY FOSTER Dental Equipment has manufactured precision Alloy Grinders in Huntington Beach, California for dental laboratories worldwide. The FOSTER Alloy Grinder is the proven workhorse for sprue separation and the finishing and polishing of chrome-cobalt Alloy framework — rugged, comfortable, and built to last.

The AG05 is the variable-speed flagship of the FOSTER Alloy Grinder line — infinitely adjustable up to 26,000 RPM via a front-panel fingertip control. When the job needs delicate work one minute and aggressive stock removal the next, this is the Grinder you reach for.

What Makes This Unique

Belt-driven speed selection (AG03/AG04) is great for two well-defined jobs — rough cutting and finish. But many CrCo cases need something in between, and stepping a belt every time costs time. The AG05's fingertip potentiometer dials the spindle to the exact RPM the cutter wants, then steps it back down for the polish.

💡 Selling Tips for Sales Team

• Sell the precision. Variable speed is the right answer when the lab is grinding a mix of materials — CrCo, titanium, ceramics. Belt-only Grinders can't dial in the sweet spot.
• Top of the AG line. If the customer is replacing an older Grinder, this is the upgrade. Don't default to the AG03 unless they explicitly want the simpler dual-speed.
• Pairs with the CDC1 Cyclone. The AG05C bundle packages this Grinder + cyclone at a better combined price.

Works with: RAY FOSTER CDC1 Cyclone Dust Collector; FOSTER F031 high-speed spindle (the AG05's native fit); standard 6-flute carbide Alloy-Grinder cutters and polishing tools.
