Sets of high quality solid tungsten carbide upcut and downcut spiral bits in the following diameters: 1/4", 3/8" and 1/2".The new formulated super micrograin composition guarantees extremely sharp long-lasting cutting edges, whereas the spiral layout allows for a more efficient chip ejection.
In addition these bits stay cooler during work and are suitable for new precision machines. Recommended for use on soft and hardwood,plywood, laminates, MDF and plastic materials. To be used on handheld routers and CNC machines.
Quick Note: Upcut spirals are always toward the router and Downcut spirals are always away from the router no matter the orientation of the router.
Part number SPIR STD and SPIRD the 1/4" diameter bit is on 1/4" shank and all other sets and bits are 1/2" shank router bits.
