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":51505875976503,"sku":"592881008","price":179.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2274\/5945\/files\/Husqvarna_Vari-Drill_B30_4-1_4-in_Diamond_Core_Drill_Bit_High_Performance_Wet_Coring_Reinforced_Concrete_Masonry_Professional_Grade_Turbo_Cutting_1.jpg?v=1779223376","url":"https:\/\/www.1toptools.com\/products\/husqvarna-vari-drill-b30-4-1-4-in-diamond-core-drill-bit-592881008-high-performance-wet-coring-for-reinforced-concrete-and-masonry-professional-grade-turbo-cutting-bit","provider":"1 Top Tools","version":"1.0","type":"link"}
