If the RPMs drop significantly, slightly reduce the feed pressure to allow the diamonds to grind through the steel without glazing. Always maintain a consistent water flow to flush out metal and concrete slurry, which prevents the bit from binding and overheating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Husqvarna","offers":[{"title":"Default Title","offer_id":51505880629559,"sku":"592881009","price":212.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2274\/5945\/files\/Husqvarna_Vari-Drill_B30_4-1_2-in_Diamond_Core_Drill_Bit_592881009_High_Speed_Turbo_Coring_for_Reinforced_Concrete_and_Masonry_Professional_Grade_Wet_Drilling_Bit.jpg?v=1767048640","url":"https:\/\/www.1toptools.com\/products\/husqvarna-vari-drill-b30-4-1-2-in-diamond-core-drill-bit-592881009-high-speed-turbo-coring-for-reinforced-concrete-and-masonry-professional-grade-wet-drilling-bit","provider":"1 Top Tools","version":"1.0","type":"link"}
