Developed originally for hardwood surfaces such as oak and beech, Ultimax is also suitable for melamine and a range of other wood-based materials.\u003c\/p\u003e\n\u003cp\u003eAt the heart of Ultimax is a high-quality aluminium oxide abrasive combined with Mirka's Selective Coating™ technology. The coating incorporates tiny cavities into the abrasive surface to help prevent clogging and increase the sanding pressure at each abrasive grain. This allows Ultimax to remove material efficiently while keeping the sanding surface cooler, extending belt life, and reducing material usage.\u003c\/p\u003e\n\u003cp\u003eThe antistatic T- and F-paper backing provides a stable, durable base for demanding wide-belt sanding, while the closed coating helps deliver a consistent finish. Available in grits from P40 to P320, Ultimax is suited to everything from coarse stock removal through to finer surface sanding.\u003c\/p\u003e\n\u003cp\u003eAvailable in a wide range of standard and custom sizes, Ultimax is particularly well suited to woodworking, furniture manufacture, joinery, cabinet making, and panel production.\u003c\/p\u003e\n\u003cp\u003eCommon applications include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSolid hardwood sanding.\u003c\/li\u003e\n\u003cli\u003eMelamine.\u003c\/li\u003e\n\u003cli\u003eVeneered panels.\u003c\/li\u003e\n\u003cli\u003eFurniture manufacture.\u003c\/li\u003e\n\u003cli\u003eJoinery and cabinet making.\u003c\/li\u003e\n\u003cli\u003eGeneral woodworking.\u003c\/li\u003e\n\u003cli\u003eWide-belt sanding machines.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCompatible machines: Wide-belt sanding machines using the appropriate belt dimensions.\u003c\/p\u003e\n\u003cp\u003eCustom sizes available: Mirka wide belts can be made to suit specific machine requirements.

Use coarser grades for stock removal and move progressively through finer grades as you refine the surface.\u003c\/li\u003e\n\u003cli\u003eDon't use excessive pressure. Ultimax is designed to make effective use of the abrasive grain; excessive pressure can increase heat and shorten belt life.\u003c\/li\u003e\n\u003cli\u003eKeep your grit progression sensible. Moving through appropriate grades will produce a more even surface and reduce the time spent removing scratches left by the previous belt.\u003c\/li\u003e\n\u003cli\u003eMake sure the belt is correctly fitted and tensioned. Poor alignment or incorrect tension can affect both sanding quality and belt life.\u003c\/li\u003e\n\u003cli\u003eUse effective dust extraction. Keeping the sanding area and workpiece clean helps maintain a consistent finish and makes it easier to identify surface defects between sanding stages.\u003c\/li\u003e\n\u003cli\u003eStore unused belts correctly. Keep them flat and protected from moisture, folding, and damage to the backing.\u003c\/li\u003e\n\u003cli\u003eFor finer sanding or pre-polish work, consider Ultimax Black. Standard Ultimax runs to P320, whereas Ultimax Black uses silicon carbide and extends to P1000, making it the more appropriate choice where much finer sanding is required.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mirka","offers":[{"title":"P80","offer_id":64792946737529,"sku":"MKA-ULTI-640-1525-80","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P100","offer_id":64792946770297,"sku":"MKA-ULTI-640-1525-100","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P120","offer_id":64752749674873,"sku":"MKA-ULTI-640-1525-120","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P150","offer_id":64792946803065,"sku":"MKA-ULTI-640-1525-150","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P180","offer_id":64792946835833,"sku":"MKA-ULTI-640-1525-180","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P220","offer_id":64792946868601,"sku":"MKA-ULTI-640-1525-220","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P240","offer_id":64792946901369,"sku":"MKA-ULTI-640-1525-240","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P320","offer_id":64792946934137,"sku":"MKA-ULTI-640-1525-320","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P400","offer_id":64792946966905,"sku":"MKA-ULTI-640-1525-400","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P500","offer_id":64792946999673,"sku":"MKA-ULTI-640-1525-500","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P600","offer_id":64792947032441,"sku":"MKA-ULTI-640-1525-600","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P800","offer_id":64792947065209,"sku":"MKA-ULTI-640-1525-800","price":166.17,"currency_code":"GBP","in_stock":true},{"title":"P1000","offer_id":64792947097977,"sku":"MKA-ULTI-640-1525-1000","price":166.17,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0579\/8985\/7461\/files\/MirkaUltimaxSandingBelt1.jpg?v=1724925039","url":"https:\/\/restorate.co.uk\/products\/mirka-ultimax-640-x-1525mm-sanding-belts-box-of-10","provider":"Restorate","version":"1.0","type":"link"}
