All Authentic EWT cutters have the optimal 3G’s of Carbide – Grade, Grind, and Geometry. 1) Grade: Carbide is basically a mixture of tungsten powder and cobalt that is fused together under high pressure and heat. The ratio of cobalt to tungsten and the size of the tungsten particles are referred to collectively as the ‘grade’. There are literally hundreds of conceivable grades and no ‘one grade’ of carbide is suited for all applications – whether wood cutting or metal cutting. 2) Grind: Authentic EWT carbide cutters yield a cutting edge that is both the sharpest and the most durable for woodturning. All of our cutters are ground on CNC grinders to ensure consistency and to prevent micro chipping of the cutting edges. We use the proper diamond wheels to produce the flattest, truest surfaces possible with minimal grinding scratches left on the surface. 3) Geometry: All authentic EWT cutters are ground to the correct angles and geometries specifically for wood and resin turning. Only when grade, grind, and geometry come together in harmony, will you have a long-lasting, high-performance cutting edge for Easy woodturning. Replacement cutter comes with 8-32 countersink machine screw.
