Specification Brand : HARFINGTON BulletPoint1 : Size - Shank diameter: 1/4"; cutting diameter: 1/4"; cutting length: 5/8"; total length: 2"; cutting hardness: HRC44-46; helix angle: 30 degree. BulletPoint2 : Material - Made of high-hardness tungsten steel, spiral cutter is wear-resistant, corrosion-resistant and has good cutting performance. Diamond-Like Carbon coating has ultra-high hardness and a low coefficient of friction, while also being effective in preventing adhesion and oxidation. BulletPoint3 : Feature - 1 flute and spiral design of the end mill router bits facilitate the smooth discharge of chips and avoid blockage during cutting. Precision cutting edges ensure clean and accurate cutting. BulletPoint4 : Application - The up cut spiral router bit is suitable for side milling, finishing, grooving, stamping, engraving and other processing of cork, hardwood, plywood, laminate, oak, MDF, etc. Can be used with cnc routers and handheld routers, etc. BulletPoint5 : Notice - Be careful to avoid excessive and too fast feeding. It is recommended to use suitable coolant or lubricant during use to dissipate heat and extend tool life.
