The upshear design lifts chips upward for efficient evacuation and clean cuts on the bottom surface, while the 3\/4\" diameter and 7\/16\" cutting height provide fast material removal with minimal passes. Industrial-grade carbide tips ensure tear-out-free results in solid wood, plywood, MDF, composites, and laminates. The 1\/4\" shank fits standard CNC collets and routers. Ideal for spoilboard resurfacing, slab flattening, flycutting, and surface planing that demands ultra-flat bottoms, fast production, and superior finish quality.\u003c\/p\u003e\n\u003cp\u003e• Upshear design – lifts chips upward for clean bottom surfaces \u0026amp; efficient evacuation\u003cbr\u003e• 3\/4\" diameter x 7\/16\" cutting height – fast material removal \u0026amp; precise leveling\u003cbr\u003e• Carbide tipped – tear-out-free cuts in solid wood, plywood, MDF \u0026amp; composites\u003cbr\u003e• 1\/4\" shank – fits standard CNC collets \u0026amp; routers securely\u003cbr\u003e• High-production performance – ideal for spoilboard resurfacing \u0026amp; slab flattening\u003cbr\u003e• Anti-kickback geometry – safer operation on CNC \u0026amp; routers\u003cbr\u003e• Precision-ground carbide – smooth, flat finishes \u0026amp; long tool life\u003cbr\u003e• Perfect for CNC spoilboards, tabletops, panels \u0026amp; surface planing\u003cbr\u003e• Amana Tool quality – premium carbide \u0026amp; precision engineering\u003cbr\u003e• FREE Shipping!\u003c\/p\u003e\n\u003ctable class=\"data table additional-attributes\" id=\"product-attribute-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth class=\"col label\" scope=\"row\"\u003eDiameter (D)\u003c\/th\u003e\n\u003ctd class=\"col data\" data-th=\"Diameter (D)\"\u003e3\/4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth class=\"col label\" scope=\"row\"\u003eCutting Height (B)\u003c\/th\u003e\n\u003ctd class=\"col data\" data-th=\"Cutting Height (B)\"\u003e7\/16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth class=\"col label\" scope=\"row\"\u003eShank (d)\u003c\/th\u003e\n\u003ctd class=\"col data\" data-th=\"Shank (d)\"\u003e1\/4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth class=\"col label\" scope=\"row\"\u003eOverall Length (L)\u003c\/th\u003e\n\u003ctd class=\"col data\" data-th=\"Overall Length (L)\"\u003e2-1\/4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth class=\"col label\" scope=\"row\"\u003eFlutes\u003c\/th\u003e\n\u003ctd class=\"col data\" data-th=\"Flutes\"\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"AMANA","offers":[{"title":"Default Title","offer_id":48488875983098,"sku":"45560","price":44.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/2666\/6746\/files\/amana-45560-spoilboard-bit-front-jpg-main.jpg?v=1773836597","url":"https:\/\/dynamitetool.com\/products\/amana-45560-bottom-cleaning-bit-14-shank","provider":"Dynamite Tool ","version":"1.0","type":"link"}
