Onsrud 60-909 | 0.500" Diameter x 0.500" Shank x 2.125" LOC x 4.000" OAL 3 Flute Solid Carbide Spiral Router Bit

Description

The Onsrud 60-909 solid carbide spiral router bit is a 3-flute design optimized for clean, chip-free plastic cutting. With a 0.500" cutting diameter and 0.500" shank, the bit provides strong support and reduced runout. A 2.125" length of cut gives ample engagement for deeper profile passes in plastic and composite materials. Overall length of 4.000" offers reach for edge work and pocketing tasks without sacrificing rigidity. Solid carbide construction maintains sharp edges and heat resistance for extended tool life on polymers. The 3-flute 0.500″ diameter spiral router bit 60-909 geometry balances chip evacuation with surface finish, reducing melt and burn on thermoplastics. Onsrud engineering ensures concentricity suitable for high-speed router spindles and CNC machines. This bit is ideal for routing, slotting, and trimming operations in plastic fabrication and sign work. Chipload control and feed-rate tuning deliver the best finish with minimal secondary operations. Precision-ground flutes promote consistent part-to-part surface quality in production runs. Use coolant or air blast where applicable to improve chip clearing and preserve tool life. The 0.500" shank fits standard collets and provides secure clamping for high-speed rotations. Its geometry supports both climb and conventional milling on a variety of plastic grades. The Onsrud 60-909 0.500″ solid carbide spiral router bit is a reliable choice for shops requiring crisp edges and repeatable routing in plastics. Select this 3-flute 0.500" diameter spiral router bit when part finish and dimensional control matter.
