W.D. Allen 10" Dual Wheel Pedestal Grinder

Model: 10" DE | Type: Double-End Pedestal | Build: Heavy Cast-Iron

Technical Specifications

• Wheel Capacity: 10" Diameter x 1" or 1.25" Width
• Spindle Speed: Approx. 1,750 – 1,800 RPM (Low-speed design for heat control)
• Motor: Industrial Induction Motor, typically 1 HP to 1.5 HP
• Electrical: 220V / 440V Dual-Voltage, 3-Phase
• Arbor Size: Commonly 1" or 1-1/4" center hole
• Construction: Full cast-iron base, motor housing, and wheel guards
• Safety: Integrated heavy-duty tool rests and (originally) cast spark shields

Key Performance Features

• Superior Stability: The sheer weight of the W.D. Allen pedestal (approx. 300+ lbs) absorbs torque and vibration, allowing for precise grinding that lighter modern benchtop models cannot match.
• Large Diameter Clearance: The 10-inch wheel capacity provides more surface area and greater clearance for large workpieces, making it ideal for heavy fabrication and weld cleanup.
• Industrial Cooling: Most vintage W.D. Allen units are designed with a low-speed motor (1800 RPM range), which reduces the risk of "burning" or ruining the temper on hardened steel tools compared to high-speed (3450 RPM) grinders.
• Bulletproof Build: These machines were manufactured during an era of "over-engineering," meaning they are easily rebuilt with standard industrial bearings and can run for several more decades.
