In plastics, the combination of HSS and Black Oxide helps maintain edge integrity for cleaner bore results even in softer materials. The long flute length allows you to reach deeper into your workpiece, reducing the need to reposition the drill frequently.\u003c\/p\u003e \u003cp\u003ePractical tips to maximize performance: keep the drill bit cool with light lubrication when cutting metal, avoid excessive feed pressure to prevent bit deflection, and periodically clear the flute of chips to maintain smooth cutting. Start with a center punch to prevent wandering on metal surfaces, then drill steadily to achieve a precise, burr-free entry.\u003c\/p\u003e \u003cp\u003eIdeal for professionals and DIY enthusiasts tackling large-diameter holes with reliability and longevity. Add this Irwin drill bit to your toolkit and experience dependable cutting edges, extended bit life, and consistent results on a range of materials.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Irwin","offers":[{"title":"Default Title","offer_id":52169061630226,"sku":"22091","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0928\/1024\/8466\/files\/22091_A.eps_High.jpg?v=1775414660","url":"https:\/\/nationalhardwaregroup.com\/products\/irwin-21-32-in-x-6-in-l-high-speed-steel-drill-bit-straight-shank","provider":"National Hardware Group","version":"1.0","type":"link"}
