Manufactured in carbide, it is particularly well suited to hardwood and panel materials where durability, accuracy and a high-quality routed surface are important. The spiral cutting geometry creates a smooth cutting action and actively transports chips upwards out of the cut, helping improve extraction and reduce chip accumulation around the cutter. With a 10 mm cutting diameter, 30 mm cutting length and 8 mm shank, this cutter is especially useful for precise groove and slot routing, including Festool VS 600 applications such as FZ 10 slot joints and SZO 20 open dovetail joints where accurate cutter diameter is critical.\u003c\/p\u003e\r\n\r\n\u003cdiv class=\"definition-products\"\u003e\r\n  \u003cstrong\u003eSmooth spiral cutting with excellent chip evacuation\u003c\/strong\u003e\r\n  \u003cp\u003eThe helical cutting edge of the HW Spi S8 D10\/30 does more than simply remove material. Its spiral geometry draws chips upward as the cutter works, helping clear the groove efficiently and supporting better dust extraction.
