It provides higher hardness, toughness, and wear resistance than standard HSS, making it far less prone to chipping.4 Flute (Z4): Four cutting edges allow for a very smooth finish because it evenly distributes the load. However, the tighter spacing means there is less room for chip evacuation, so it is strictly meant for shallow or lighter cuts rather than deep hogging\/roughing.Slot Drill (Center Cut): The teeth meet in the very center of the tool, enabling you to plunge straight down into solid material (like drilling) before moving laterally.Finishing: The geometry of this tool is designed for taking light depths of cut to yield tight tolerances and a mirror-like surface.Short Length: The short, stout build ensures maximum rigidity, preventing tool deflection (bending) to maintain dimensional accuracy during profiling.Weldon Shank: This means the tool has a flat machined into the shank for a set-screw to lock into. It prevents the cutter from spinning or pulling out of the machine's holder under high-torque, heavy-load milling.Coated: A specialized surface treatment (such as TiAlN or AlTiN) is applied to the tool. This drastically reduces heat, friction, and wear, allowing you to run the machine at higher speeds and extend the overall lifespan of the tool.45° Helix: A high 45-degree twist (spiral) angle along the body of the cutter reduces cutting resistance, mitigates machine vibrations (chatter), and smoothly pushes chips upward and away, yielding a superb surface finish. \u003cspan\u003e  \u003c\/span\u003e\u003c\/span\u003e\n\u003c\/div\u003e","brand":"KENDU made in Spain","offers":[{"title":"Default Title","offer_id":53858641609043,"sku":"1442.91.01800","price":14.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/8615\/7299\/files\/KENDU_1442.80_._91.png?v=1779884809","url":"https:\/\/www.toolsmondo.com\/products\/1442-91-01800","provider":"ToolsMondo","version":"1.0","type":"link"}
