10mm Bore to 16mm Step Arbor Reducer Flange – Precision 3.5mm Adapter for Grinding & Saw Blade Mounting

The 10mm Bore to 16mm Step Arbor Reducer Flange (3.5mm Step) is a precision-machined adapter engineered to mount 16mm bore grinding wheels and saw blades securely onto 10mm machine arbors and motor shafts.

Key Features

• Precision Step Sizing: Adapts a 10mm shaft diameter to a 16mm wheel/blade bore with exact concentric tolerances to eliminate wobble and vibration.
• 3.5mm Step Height: Provides deep, positive engagement in the wheel core for maximum stability and true rotational balance.
• Durable Machined Construction: Machined from solid, wear-resistant alloy with flat mating surfaces to ensure uniform axial clamping pressure without distortion.
• Universal Compatibility: Fits lapidary bench arbors, small tile/trim saws, polishing spindles, and custom rotary drive setups.

Recommended Applications

• Mounting 16mm bore diamond saw blades onto 10mm motor shafts or arbor shafts.
• Adapting 16mm bore grinding wheels, laps, and sanding drums to compact bench grinder spindles.
• Centering and stabilizing rotary abrasive accessories in lapidary, jewelry, and metal workshops.

Operating Guidelines

• Confirm that your motor shaft diameter is exactly 10mm and accessory center bore is 16mm before mounting.
• Ensure shaft, flange, and wheel arbor surfaces are clean and free of metal burrs or debris.
• Tighten retaining nut securely to manufacturer torque specifications before starting rotation.
