Material: Carbide + Steel Shank Diameter: 8mm/0.31 Blade Diameter: 12.7mm/0.5 Blade Length: 25mm/1 Overall Length: 82mm/3.23 Package: 1 8mm shank router bit. 8mm Cutter: Shank Diameter: 8mm/0.31 Blade Diameter: 12.7mm/0.5 Blade Length: 25mm/1 Total Length: 82mm/3.23 Double Cutter Bearing: This bit can be used on higher or lower models. Particularly suitable for jig work when milling round or curved wood with sensitive end grains. High quality material: high hardness, good wear resistance, greatly improve service life. High Frequency Welding: Cutters (C3 micrograin tungsten carbide) for smooth cutting in billets, resulting in clean, chip-free cleaning Application: This tool can process synthetic woodworkers with smooth surfaces such as hardwood, soft wood, wood, etc., but avoid processing metallic materials such as copper and iron and non-wood materials such as sand and stone.
