CNC Nesting Router Bits

This In-Presta™ router bit is a 1/4″ diameter CNC Nesting router bit with 3 flute solid carbide cutting edges brazed into a steel 1/2″ shank. Use a three-flute bit where fine finish is paramount. Three flutes balance the bit in order to eliminate vibration that degrades the cut finish. Three cuts per revolution will yield a smooth surface and increased feed rates. Not for use in hand-held routers or router tables. CNC use only. 1/4″ Diameter, 3/4″ Cut Length, 1/2″ Shank, 3″ Overall Length. Excellent for nesting and grooving at an extremely fast feed rate which increases cost savings The unique design contributes to superb performance and excellent cutting results Designed primarily for high-speed CNC production Long-lasting, fine micro-grain extra hard carbide resulting in long tool life before re-sharpening Excellent for Cutting: Laminated Particle Board, MDF & Melamine: Feed rate up to 800 IPM at 18,000 RPM Plywood: Feed rate up to 500 IPM at 18,000 RPM CMT's features the extra-hard DLCS Chrome coating.
