Manufactured by LMT Onsrud, this High Speed Steel (HSS) bit delivers clean, efficient cuts in challenging foam and wood materials. These Upcut router bits are engineered for professional CNC routing applications. The HSS construction ensures durability and consistent performance across a wide range of materials.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eOnsrud 40-550 HSS Series Upcut Spiral Router Bits – Features \u0026amp; Applications\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe LMT Onsrud 40-550 series uses High Speed Steel to provide excellent chip evacuation. The Upcut spiral geometry pulls chips upward and away from the cut. This keeps the cutting zone clear and reduces heat buildup. These HSS Router Bits are ideal for production environments where reliability matters. LMT Onsrud is a trusted name in precision cutting tools for CNC machines.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan style=\"margin: 0px; padding: 0px; color: #ff0000;\"\u003e\u003cspan style=\"margin: 0px; padding: 0px; color: #000000;\"\u003eExcellent for: \u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan style=\"margin: 0px; padding: 0px; color: #ff0000;\"\u003e\u003cspan style=\"margin: 0px; padding: 0px; color: #000000;\"\u003eCross linked Polyethylene Foam (XLPE)\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan style=\"margin: 0px; padding: 0px; color: #ff0000;\"\u003e\u003cspan style=\"margin: 0px; padding: 0px; color: #000000;\"\u003eExpanded Polypropylene (EPP)\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan style=\"margin: 0px; padding: 0px; color: #ff0000;\"\u003e\u003cspan style=\"margin: 0px; padding: 0px; color: #000000;\"\u003eNatural Woods\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCross linked Polyethylene Foam (XLPE) is a dense, closed-cell foam used in packaging and insulation. Expanded Polypropylene (EPP) is lightweight and impact-resistant, making it popular in automotive and protective applications. Natural Woods benefit from the Upcut spiral design, which produces smooth, splinter-free edges. These Router Bits handle softwoods and hardwoods with equal precision. The upward chip flow keeps the workpiece surface clean during cutting.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eChoosing the right HSS router bit is critical for achieving quality results. These bits are available in multiple configurations to suit different CNC setups. LMT Onsrud engineers each bit to tight tolerances for consistent diameter and runout. High Speed Steel offers a cost-effective alternative to carbide for foam and softer wood materials. These Upcut Router Bits are a reliable choice for shops cutting foam components daily.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eProper feed rates and spindle speeds extend the life of any HSS bit. Consult the LMT Onsrud speed and feed charts for recommended parameters. Using the correct settings ensures the High Speed Steel maintains its edge longer. Always inspect Router Bits before each use for signs of wear or damage. Replacing worn bits promptly protects your workpiece and your CNC machine.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"LMT Onsrud","offers":[{"title":"1\/2\" \/ 3-5\/8\" \/ 1\/2\"","offer_id":42122927112404,"sku":"40-562","price":108.07,"currency_code":"CAD","in_stock":true},{"title":"1\/2\" \/ 4-1\/8\" \/ 1\/2\"","offer_id":42122927145172,"sku":"40-564","price":122.79,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0337\/4651\/8147\/products\/onsrud-40-550-series-upcut-spiral-cnc-router-store-11343.jpg?v=1777925754","url":"https:\/\/www.cncrouterstore.ca\/products\/40-550-upcut-spiral","provider":"CNC Router Store","version":"1.0","type":"link"}
