Knew Concepts Mk IV 3" HD Jewelers Saw Frame-With 360 Degree Swivel Blade Clamps-Cam Lever Tension

The Knew Concepts Mk IV 3" Heavy-Duty Jeweler’s Saw Frame with Cam Lever Tension and 360° Swivel Blade Clamps is built for maximum rigidity and control. This upgraded Mk IV design features a heavier frame that delivers up to 60 pounds of blade tension—two to three times greater than earlier generations—eliminating frame flex and dramatically improving accuracy on dense or hard materials.

Key Features

• Heavier Mk IV frame provides exceptional strength and stiffness for precision cutting.
• Cam lever tension system allows quick, repeatable blade changes without adjusting the screw tension every time.
• 360° swivel blade clamps let you rotate the blade freely in any direction, with detents every 45° for accurate repeatable positioning.
• Maintains full cutting accuracy and reduces blade breakage even under heavy tension.
• Machined from heat-treated aluminum for long life, strength, and corrosion resistance.
