138-Inch Blade Length
The specified Wellsaw 850A replacement blade features a 138-inch blade length. Correct blade length is essential for proper installation, tensioning, tracking, and safe operation.
1-Inch Blade Width
The 1-inch blade width provides a strong balance of rigidity and flexibility, helping minimize blade deflection while supporting accurate cutting of medium and large metal sections.
Heavy-Duty Scissor-Head Compatibility
The compatible Wellsaw 850A uses a rugged scissor-head design with substantial machine construction intended to provide stable cutting and reduced vibration during demanding workshop operation.
Precision Metal Cutting
A properly selected replacement blade can deliver smooth, accurate cuts through carbon steel, stainless steel, aluminum, tubing, pipe, bar stock, and other compatible materials.
Manual Swivel Vise Compatibility
The machine uses a quick-acting manual screw vise capable of approximately 45-degree adjustment, allowing the blade to be used for straight and miter-cutting applications.
Adjustable Gravity Feed
The Wellsaw 850A uses a counterbalance spring and adjustable feed arrangement to regulate the saw frame's downward cutting movement according to the material being processed.
Hydraulic Feed Control
A variable hydraulic cylinder helps control the downward approach speed, supporting smoother blade engagement and more consistent cutting performance.
Four-Speed Pulley Drive
The machine uses a four-step pulley configuration with approximate blade speeds of 50, 100, 175, and 275 SFPM, allowing speed selection according to material type and thickness.
Wet-Cutting Coolant System
Compatible wet-cutting configurations feature an approximately 8-gallon flood coolant system with pump and tank to help control heat, reduce friction, and clear chips.
Automatic Shut-Off Compatibility
The Wellsaw 850A platform uses a mechanical limit trigger that can interrupt the electrical circuit and stop the motor when the blade completes the cut.
Rite-Tension® Compatibility
The compatible machine incorporates a manual blade-tensioning system designed to simplify blade installation and help maintain proper blade tension during cutting.
Stable Blade Tracking
Correct blade tension, guide alignment, wheel condition, and machine setup help maintain stable tracking and reduce blade wandering throughout operation.
Reduced Vibration
Rigid machine construction combined with proper blade selection and adjustment helps reduce vibration and supports smoother, more accurate cuts.
High Cutting Capacity
The referenced Wellsaw 850-series configuration provides approximately 10.5-inch round capacity and up to 10 inches high × 16 inches wide rectangular capacity.
Extended Blade Service Life
Proper blade break-in, tooth pitch, tension, feed control, cutting speed, coolant management, and machine maintenance can help reduce premature tooth wear and extend service life.
