Woodturners, this 8-inch Cole Jaw set is exactly what you need for finishing and polishing your bowl projects! Now, pay attention - this set is specifically designed for VINWOX SCR4-4NV and SCK4-3.5NV Nova chucks, but it also fits original Nova, Supernova, G3, Titan, and Midi chucks. Make sure to check your chuck brand before ordering to avoid compatibility issues. So what do Cole Jaws actually do? They're perfect for re-chucking bowls to remove those annoying chuck marks from the bottom or to re-shape bottoms of bowls that have already been turned. The set includes 4 flat jaw plates made from high-quality 45# steel, each with 6 holding positions and holes spaced about 0.2 inches apart. You also get 16 buffers total - 8 long and 8 short - that provide better holding power on various shaped bowl rims without damaging your finished work. Installation is straightforward - just mount the Cole Jaws on your chuck's sliding jaws following the 1,2,3,4 numbering system to ensure they're firmly secured with no movement. The maximum turning speed is 800 RPM, which is plenty for finishing work, and the diameter range handles workpieces from 2.85 inches up to 7.5 inches. At just 1.85 kg (4 pounds), the set is lightweight but built to last through years of use. If you're tired of struggling to finish bowl bottoms or want professional-looking results without chuck marks, this Cole Jaw set is one of those essential woodturning accessories that takes your craftsmanship to the next level. It's that game-changing tool that separates amateur work from professional-quality finished pieces.
