46264-K Solid Carbide CNC Spektra™ Extreme Tool Life Coated Spiral Carbon Graphite Carbon Fiber Panel Cutting 1/4 Dia x 3/4 x 1/4 Shank x 3 Inch Long Down Cut Router Bit

46264-K Solid Carbide CNC Spektra™ Extreme Tool Life Coated Spiral Carbon Graphite Carbon Fiber Panel Cutting 1/4 Dia x 3/4 x 1/4 Shank x 3 Inch Long Down Cut Router Bit Industrial-quality Amana Tool spiral router bit for CNC/router applications. Key dimensions: Diameter: 1/4"; Cutting Height/Length: 3/4"; Shank: 1/4"; Overall Length: 3". Introducing Amana Tools®'s carbon graphite and carbon fiber cutting solid carbide router bits designed to produce a minimum failure in composite materials such as layers separating and a significant loss of mechanical toughness. The rapidly growing use of Carbon Fiber Reinforced Polymers (CFRP) necessitates tooling designed to effectively meet the challenges of such composites. Experts have recognised the need for a tool geometry combining a highly abrasion-resistant carbide substrate generous fluting and an impact zone that not only "shatters" the hard carbon fibers but also keeps heat down.
