Description
RAY FOSTER Model AG04 Alloy Grinder with Built-in Dust Collector — 220V
Dual-speed (10K/24K RPM) Grinder with self-contained dust collector — one-piece station, no external unit required (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 AG04 packages the proven FOSTER automatic-spindle Grinder with a fully self-contained dust collector — a one-piece station for labs that don't want a separate extraction unit on the bench.
Key Features
- Self-contained dust collector built into the chassis — no external unit required
- Dual belt-controlled speeds: 10,000 and 24,000 RPM
- Heavy-duty 1/3 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
- UL-recognized and CSA-certified motor for electrical safety
- Manufactured in the United States — RAY FOSTER, family-owned since 1938
- 220V 50/60 Hz
Key Selling Points
- One-box solution — Grinder + dust collection in a single unit
- Saves bench space vs. running a separate cyclone or shop-vac
- Same time-saving FOSTER automatic spindle as the AG03
- UL/CSA-certified motor — lab-insurance-friendly
- Larger 1/3 HP motor (vs 1/4 HP on AG03/AG05) for higher torque under load
What Makes This Unique
Most labs running a basic Grinder need to add a dust collector after the fact. The AG04 ships with collection built in — no hose run, no extra outlet, no extra cord. The right choice when bench space is tight or the lab doesn't already own a cyclone.
💡 Selling Tips for Sales Team
- Sell the all-in-one story. Grinder + dust collection in a single unit. No additional cyclone purchase needed for most labs.
- Sell the spindle. The high-speed automatic spindle is FOSTER's original design and the most copied feature in this category.
- Lab-insurance angle. UL/CSA-rated motor, totally enclosed housing.
- Position vs. AG03-MDCC: AG04 has a self-contained internal bag collector. AG03-MDCC adds the external CDC1 Cyclone — cyclones capture finer particulates and are better for high-volume CrCo labs. AG04 is the budget-friendly all-in-one.
- Lab managers love it: single SKU, single warranty, single setup — no second machine to maintain.
