Amana tool 45186-3 CNC Nesting In-Presta 3 Flute Carbide Tipped (Brazed to Steel Shank) Straight Plunge High Production 5/16 D x 1-1/8 CH x 1/2 SHK x 3 Inch Long, 3-Flute Router Bit

High Production Straight Plunge Router Bits In choosing a straight bit for any application, always select one with the shortest cutting edges and the shortest overall length that will reach the required cut depth. Excessive length intensifies deflection and vibration, which degrade cut quality and lead to tool breakage.  Extended life fine micro-grain harder carbide Superior geometric design Advanced grinding technology that improves the carbides' resistance to wear Super clean cuts Carbide Tipped (unless noted otherwise) Use a two-flute bit where fine finish is paramount. Two flutes balance the bit, eliminating vibration that degrades the cut finish. Two cuts per revolution yield a smooth surface, but feed rate is slightly reduced. Excellent for cutting: Wood MDF Plywood IN>PRESTA™ CNC Router Bits (item #45185-M, #45408-3 and #45186-3) Up to 800 inches per minute!*  For cutting 3/4" material thickness in one pass 3 Flute for improved surface finish  Small diameter equals minimal material waste Excellent for nesting & grooving at an extremely fast feed rate which increases cost savings Small cutting diameter CNC Nesting router bit with solid carbide cutting edges brazed into steel 1/2" shank The unique design contributes to superb performance and excellent cutting results Designed primarily for high speed CNC production Long lasting harder carbide 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*** * Up to 800 IPM feed rate at 18,000 RPM cutting laminated particle board. Rate may change depending on material and CNC machine type.  ** IPM: Inches Per Minute *** RPM: Revolutions Per Minute
