Festool HW Spi S8 D6/21 Solid Carbide Spiral Groove Cutter 6 mm with 8 mm Shank

Overview

Festool Spiral Groove Cutter HW Spi S8 D6/21 At a Glance: 6 mm solid carbide spiral groove cutter with a 21 mm cutting length, 50 mm overall length and 8 mm shank. Precision diameter for Festool VS 600 FZ 6 and SZO 14 jointing applications. Route precise grooves and accurately matched joints with the Festool HW Spi S8 D6/21 spiral groove cutter. Its solid carbide construction is particularly suited to hardwood and panel materials, while the spiral cutting action draws chips upwards from the groove. This helps clear the cutting area during routing and supports smooth progress through the workpiece. The accurately controlled 6 mm cutting diameter makes this cutter suitable for the specified FZ 6 finger-joint and SZO 14 open-dovetail jointing procedures with the Festool VS 600 system. It also provides a useful cutting format for suitable grooving, rebating, elongated-hole and guided copy-routing tasks. The 8 mm shank requires the correct router collet and a guidance arrangement matched to the operation. Spiral Cutting Action with Upward Chip Clearance The helical cutting geometry moves chips towards the top of the cut. Keeping the groove clear helps limit chip recutting, although effective dust extraction and appropriate cutting passes remain important. Product Highlights • 6 mm cutting diameter: For narrow grooves and the specified precision jointing applications. • Solid carbide construction: Suitable for demanding hardwood and panel-material routing. • Spiral chip evacuation: Draws chips upwards from the cutting area. • 21 mm cutting length: Provides the specified usable cutting section. • 8 mm shank: Fits a compatible router equipped with an 8 mm collet. • VS 600 application: Specified for FZ 6 and SZO 14 jointing procedures with the appropriate system components. Product Compatibility • Router mounting: Requires a compatible router with the correct 8 mm collet and adequate cutter clearance. • Festool router examples: OF 1010, OF 1400 and OF 2200 with the appropriate collet and setup. • Festool VS 600 FZ 6: For the specified finger-joint machining procedure using the correct template and copying ring. • Festool VS 600 SZO 14: Used as part of the open-dovetail machining procedure with the prescribed template and complementary tooling. • Material applications: Particularly suited to hardwood and suitable panel materials. Jointing system note: This is a cylindrical spiral groove cutter, not a dovetail-profile cutter. Its use in SZO 14 joints forms part of the prescribed machining sequence. Follow the VS 600 instructions for the required templates, copying rings and complementary cutters.
