Festool HW Spi S8 D8/25 Solid Carbide Spiral Groove Cutter 8 mm × 25 mm with 8 mm Shank

Overview

Festool HW Spi S8 D8/25 Solid Carbide Spiral Groove Cutter At a Glance: 8 mm cutting diameter, 25 mm cutting length and 8 mm shank. Solid carbide construction with an upward chip-clearing spiral for routing grooves and template-guided cut-outs in suitable panel materials and hardwood. Create clean grooves and accurately guided cut-outs with the Festool HW Spi S8 D8/25 Spiral Groove Cutter. Its solid carbide construction is particularly suited to panel materials and hardwood applications, while the spiral cutting geometry provides a progressive shearing action that reduces cutting pressure and promotes smooth routing. The right-hand spiral draws chips upwards from the cut, helping clear the groove and supporting effective extraction when used with a suitable dust extraction setup. With an 8 mm cutting diameter, 25 mm cutting length and 55 mm overall length, this cutter is a practical choice for furniture, cabinetry and joinery tasks requiring narrow grooves or controlled cut-outs. Fit it to the correct 8 mm collet in a compatible Festool router and use an appropriate fence, guide or template to establish the cutting path. Spiral Cutting Action with Upward Chip Removal The helical cutting edges engage the material progressively and carry chips upwards. This helps remove debris from the cutting area, particularly when routing grooves where chips can otherwise accumulate around the cutter. Product Highlights • Solid carbide construction: Designed for demanding routing applications in suitable panel materials and hardwood. • 8 mm cutting diameter: Suitable for narrow grooves and appropriately guided cut-outs. • 25 mm cutting length: Provides the stated usable cutting section for controlled routing operations. • Upward chip evacuation: The spiral draws chips out of the groove towards the extraction area. • Reduced cutting pressure: The drawing cut supports clean results and smooth operation. • 8 mm shank: Secures in the appropriate 8 mm collet of a compatible router.
