Variant Selection: Single-flute variants are recommended for soft materials, thin workpieces, controlled deburring and less rigid fixed machines. Three-flute variants are intended for efficient cutting on rigid, accurately aligned equipment such as machining centres.
Size Selection: The cutter diameter must be larger than the required finished chamfer diameter. The manufacturer recommends selecting a cutter approximately 1.5 times the required chamfer diameter.
