This is a precision arbor shaft designed specifically for small DC drill chuck motors (like popular 775, 795 models). Its core function is to act as a secure converter, transforming your motor's smooth output shaft into a standard M10 external thread. This allows you to mount a vast array of 10mm-bore accessories—such as cutting discs, grinding wheels, and buffing pads—turning a simple motor into a versatile DIY cutting, grinding, or polishing tool.
Color: Black; Height: 42mm/1.65inch; Outer Diameter: 16 mm/0.63 inch; Back Hole Dia: 8 mm/0.31 inch; Material: 45 Carbon Steel; Packing List: 1 x Motor Shaft Coupler, 1 Hex Wrench and 2 Screws
Perfect for small DC motors, this 45 steel (1045) arbor ensures a solid, vibration-free connection, offering excellent wear resistance and strength. It integrated set screw locks securely onto motor shafts. At the same time, the standard M10 thread allows you to easily create your own mini table saw, cutter, or polisher for hobby projects, model building, and small workshop tasks.
Confirm your motor shaft diameter matches this arbor's bore. Only use accessories (blades/wheels) that are rated for high RPM and intended for rotary tool use. The maximum RPM on the accessory must exceed your motor's no-load speed. Always wear safety glasses and proper protective equipment during operation. Check tightness before each use.
Size Matching: Ensure the adapter fits both your tool’s shaft (M10) and the accessory’s mounting hole - mismatched sizes cause instability. Full Tightening: Loose screws may lead to accessory slippage - check tightness before each use.
