Amana tool 46460-Z SC Spiral Plunge with Corner Radius 1/16 R x 1/4 Dia x 3/4 CH x 1/4 SHK 2-1/2 Inch Long Up-Cut ZrN Coated Router Bit

Solid Carbide Spiral Flute Plunge with Corner Radius Router Bits   Spiral bits combine a shearing action in cutting with an augering action in chip clearance. The shearing action yields an especially clean & accurate cut, while the augering action clears chips from the cut. The “up-cut” shears from the bottom up, pulling chips from the bottom up, thus allowing deeper penetration with less stress on the tool. An excellent choice for mortising.Unique carbide grade for longer lifetime Produces a superior finish and longer tool lifeRazor-sharp cutting edges/polished flutes'Can be used with hand-held, table-mounted portable routers and CNC machinesIndustrial quality Excellent for cutting:AluminumMDFSoft/Hard PlasticSoft/Hard WoodBenefits of Zirconium Nitride (ZrN) CoatingCreates a harder and tougher cutting edge allows for a prolonged cutting edge life and helps to prevent the build-up of material in the flutes while cuttingHave the tendency to run/spin much faster than an uncoated toolOptimized flute geometry and low Total Indicated Runout (TIR) guarantees clean cuts, essentially eliminates sanding and reduces chatter (where the machine or work piece vibrates) under high chip loads (when used with low TIR spindles)High flute volume supports high feed rates and chip loadsHigh aspect ratio for single pass deep-reach cuttingFlute geometry optimized for cutting sign foam, sign board, hardwoods, thermoplastics and phenolic composites
