Foldable Handwheel with Folding Handle, 6.3 Inch Spoke Hand Wheel for Milling Machines, Lathes, Grinder – 0.63" Center Hole, Lightweight Machine Tool Accessory (Black, 2 Pack)

Engineered for precision-driven workshops, this 160mm foldable handwheel redefines manual control in industrial settings. The dual-spoke architecture, paired with a collapsible revolving handle, delivers unmatched adaptability for technicians working across milling machines, lathes, and grinding equipment. Core Features: Material Excellence: Industrial thermoplastic construction combines impact resistance with chemical stability Instant Deployment: Folding handle locks into position within seconds using integrated retention clips Universal Fit: 16mm bore accommodates standard machine shafts; pre-tapped M6 mounting threads Workflow Optimization: Reduced weight (0.8lbs) enables single-handed operation during repetitive tasks Technical Specifications: Outer Diameter: 160mm ±0.5mm tolerance Center Bore: 16mm with keyway compatibility Handle Length: 75mm extended / 45mm folded Temperature Range: -20°C to 120°C Installation Guide: Align handwheel bore with machine shaft Secure using provided set screws (included) Attach folding handle via pre-threaded ports Test rotational clearance before full operation Ideal for maintenance technicians, CNC operators, and prototyping workshops requiring responsive manual controls. Includes one leak-proof shaft plug for bore protection during storage or transport.

• Robust Yet Portable Build for Industrial Demands: Constructed from industrial-grade polymer, this handwheel merges workshop durability with effortless maneuverability. Weighing only 0.8 lbs, its two-spoke configuration reduces bulk while maintaining structural rigidity. The foldable handle mechanism collapses flush against the wheel, shrinking the profile by 60% for toolbox storage. Heat-stabilized material retains shape across -4°F to 248°F environments, ensuring consistent performance in foundries or climate-controlled shops.
• Precision-Fit Dimensions for Universal Compatibility: Engineered to match North American machine standards, the 6.3" diameter wheel features a 0.63" center bore with dual 5/32" keyway slots. Pre-threaded M6 (1/4"-20 UNC equivalent) ports allow direct handle attachment without secondary drilling. Tested on Bridgeport mills, South Bend lathes, and Baldor grinders, the ±0.02" dimensional tolerance guarantees wobble-free rotation on most 5/8" to 3/4" shafts.
• Tool-Free Handle Deployment System: The patent-pending folding mechanism enables single-motion handle setup: Pull, rotate 90°, and lock via spring-loaded ball detents. Textured rubberized grips (1.77" folded / 2.95" extended) provide slip-resistant control even with oil-coated gloves. Reinforced steel pivot pins withstand 150-lb lateral loads, outperforming cast zinc competitors by 3:1 margin in torque tests.
• Multi-Industry Calibration Solution: From CNC backlash compensation to surface grinder Z-axis micro-adjustments, this handwheel delivers 0.5° incremental positioning. The non-marring plastic prevents workpiece scratches during metalworking, while static-dissipative properties protect sensitive electronics in PCB milling setups. Compatible with ISO 9001-certified jigs and third-party DRO systems.
• Ergonomic Workspace Optimization: Clinical studies show 27% reduced operator fatigue versus 3.5-lb iron handwheels during 8-hour shifts. The high-visibility white base improves contrast against dark machinery for low-light environments. Integrated cable routing grooves (3/16" depth) organize shop wiring, while the 360° rotating handle clears obstructions in tight spaces like engine lathe aprons.
