RAY FOSTER Model AG05C — Variable-Speed Alloy Grinder + Cyclone Dust Collector (110V)
Top-of-line bundle: variable-speed AG05 Grinder + CDC1 Cyclone Dust Collector in one catalog number
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 AG05C is RAY FOSTER's top-of-line bundle: the variable-speed AG05 Grinder paired with the CDC1 Cyclone Dust Collector. Variable RPM control up to 26,000 plus cyclone-based dust capture in a single catalog number — the configuration high-volume crown-and-bridge and partial-denture labs ask for by name.
Key Features
- Bundled CDC1 Cyclone Dust Collector for superior fine-particulate capture
- Variable-speed control via front-panel potentiometer, up to 26,000 RPM
- Heavy-duty, high-torque 1/4 HP Grinder motor in totally enclosed housing
- 1 HP CDC1 cyclone motor, 112 CFM suction, 59 dB noise level
- Precision high-speed automatic spindle
- Pre-wired auto on/off — cyclone runs only with Grinder
- UL-recognized and CSA-certified motors
- 110V 50/60 Hz (US domestic only — no 220V bundle available)
Key Selling Points
- The full FOSTER experience in one purchase — variable speed + cyclone
- Cyclone capture beats bag-filter for fine Alloy dust
- Single warranty, single setup, single parts source
- Variable speed = the right machine for both rough cutting and finish
What Makes This Unique
This is the configuration experienced lab managers spec when building a new bench from scratch. The AG05's precision speed control plus the CDC1's industry-leading dust extraction — without the back-and-forth of buying two separate Units.
💡 Selling Tips for Sales Team
- This is the "best" in a good-better-best ladder. AG03 = good, AG04 = better, AG05C = best.
- Workflow story. Variable speed lets a single tech do rough cutting, intermediate shaping, and polish on one machine.
- Math the bundle vs. parts. AG05 + CDC1 bought separately costs more than the AG05C. Show the line-item comparison.
- Lab-build deals. When quoting a new-lab equipment package, position AG05C alongside the model trimmer, vacuum former, and lathe as the "Grinder bench" corner.
- OSHA / lab-health angle. Cyclone-based extraction handles fine CrCo and titanium dust — the right answer for compliance-conscious labs.
