Description
RAY FOSTER Model AG05 Variable-Speed High-Speed Alloy Grinder — 110V
For over 85 years, RAY FOSTER Dental Equipment has manufactured precision Alloy Grinders in Southern 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 calls for delicate work one minute and aggressive stock removal the next, this is the Grinder you reach for.
Key Features
- Fingertip variable-speed control via front-panel potentiometer
- Speed range: up to 26,000 RPM
- Heavy-duty, high-torque 1/4 HP motor in totally enclosed housing
- Fully adjustable safety shield and integrated light assembly
- Adjustable spindle working height for operator comfort
- Precision high-speed automatic spindle
- 2.5″ suction port for RAY FOSTER CDC1 Cyclone or any shop dust system
- Power output connection for automatic on/off of the dust collector
- UL-recognized and CSA-certified motor
- Manufactured in the United States — family-owned since 1938
- 110V 50/60 Hz
Key Selling Points
- Variable speed = one machine for finishing AND aggressive grinding
- Higher top-end RPM (26,000) than the dual-speed AG03/AG04
- Same automatic spindle, same enclosed motor, same safety package
- Front-panel control — no reaching around to flip belt positions
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
- 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 (#AG05C) packages this Grinder + cyclone at a better combined price.
- Voltage for export. 220V variants ship for Latin America, the Caribbean, and Europe out of our Miami consolidation.
