RAY FOSTER - AG03-MDC Alloy Grinder with Automatic Spindle, 110V 50/60Hz

RAY FOSTER Model AG03-MDC 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 AG03-MDC delivers dual belt-controlled speeds of 10,000 and 24,000 RPM with the legendary FOSTER automatic spindle — the reference standard in dental-laboratory Alloy grinding. The MDC suffix denotes the dust-collector-ready configuration with a 2.5″ external suction port.

Key Features

• Dual belt-controlled speeds: 10,000 and 24,000 RPM
• Heavy-duty 1/4 HP capacitor-start 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 — change tools without stopping the motor
• 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
• Compact design — minimal bench footprint
• Manufactured in the United States — family-owned since 1938
• 110V 50/60 Hz

Key Selling Points

• Time-tested design refined over decades of daily lab use
• Automatic spindle saves minutes per case — no motor stop for tool changes
• Compact 10.25″ W × 11.75″ L footprint — fits any bench
• Dust-collector-ready — pair with RAY FOSTER CDC1 for a complete clean-air station
• Backed by the RAY FOSTER factory in Huntington Beach, CA

What Makes This Unique

The FOSTER automatic spindle is the original. Every other lab Grinder on the market either licenses, copies, or imitates it. The MDC variant adds a manual dust-collector connection so labs can run their existing extraction system without rewiring.

SELLING TIPS

• Lead with workflow. Ask the lab what they currently use for sprue separation. If they’re running a generic bench Grinder, walk them through how the FOSTER automatic spindle changes tools without shutting the motor down.
• Sell the spindle. The high-speed automatic spindle is the single most copied feature in this category. FOSTER invented it. Replacements are user-serviceable in the field.
• Talk safety to the lab owner. UL/CSA-rated motor, totally enclosed housing, integrated safety shield with light.
• Bundle the dust collector. Step the customer up to the AG03-MDCC (this Grinder + CDC1 Cyclone) for one PO, one warranty, one bench.
• Voltage for export. 220V variants ship for Latin America, the Caribbean, and Europe out of our Miami consolidation.
• AG03 vs. AG04 vs. AG05 cheat sheet: AG03 = belt-speed Grinder, no built-in dust; AG04 = same Grinder + self-contained dust collector; AG05 = variable speed up to 26,000 RPM.
