This is a \u003cstrong\u003eplaner knife\u003c\/strong\u003e designed for \u003cstrong\u003eplaning solid wood and other wood materials\u003c\/strong\u003e. If you use your planer for fitting doors, cleaning up rebates, trimming wallboards, or breaking edges on beams and trim, this is the wear part that keeps the cut quality where it should be.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is not just that it is a replacement blade, but how it cuts. Festool uses a spiral blade arrangement that creates a pulling cut. In real use, that means a smoother planing action and better finish quality on common planing tasks. For adjustment work on doors, infill panels, cornices, and similar finish pieces, that cleaner cut saves time on cleanup and sanding.\u003c\/p\u003e\n      \u003cp\u003eThe blade itself is carbide, which is the right material for an accessory like this because durability is the whole point. A planer blade takes a beating, especially if you are doing repeated passes in hardwood, jobsite softwood, or engineered wood materials. The carbide construction helps the edge stay serviceable longer under normal planing use.\u003c\/p\u003e\n      \u003cp\u003eFestool also got the installation side right. The blade is changed with just three screws, and the fit is designed so the blade seats correctly without needing to adjust blade protrusion. That matters because it cuts down setup time and takes some of the guesswork out of maintenance. When a replacement part goes in cleanly and runs true, you spend less time tuning and more time working.\u003c\/p\u003e\n      \u003cp\u003eAt 82 mm wide, this planer knife is sized for standard planing tasks in the matching head setup. It is also very light at 0.03 kg, so it is clearly a compact replacement component rather than a bulky accessory kit. The emphasis is on accurate fit, smooth running, and dependable cutting performance rather than added complexity.\u003c\/p\u003e\n      \u003cp\u003eCompatibility matters with accessories like this. The product data specifically notes that it is \u003cstrong\u003enot suitable for HL 850\u003c\/strong\u003e, so buyers need to match the blade to the correct planer head before ordering. That is the kind of detail that prevents downtime and return headaches.\u003c\/p\u003e\n      \u003cp\u003eIf you are a carpenter, finish contractor, remodeler, cabinet installer, or serious DIY user maintaining a Festool planer setup, this is the kind of replacement part worth buying correctly the first time. The Festool Spiral Knife HW 82 SD HLC 82 is for users who care about cut quality, proper fit, and quick serviceability, not just grabbing the cheapest blade that happens to be close in size.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eBuilt for Clean Planing
