Use cutting fluid on every countersink in steel — even a small amount of thread-cutting oil dramatically improves cut quality and extends bit life. For aluminium, use a dedicated aluminium cutting lubricant or WD-40 — standard cutting oils are less effective on non-ferrous metals. Size selection: the countersink should be sized so the fastener head sits flush — test on scrap material of the same thickness before countersinking the actual workpiece.\u003c\/p\u003e","brand":"Snagg A Drill Bit","offers":[{"title":"5PCS Drill Bit Set \/ Hexagonal","offer_id":46089446359213,"sku":"14:10#5PCS Drill Bit Set;200341261:202813809","price":32.01,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/5103\/4285\/files\/f6a17477-ead1-4df0-86fc-c7d06f9fdae6520499.png?v=1780833330","url":"https:\/\/snaggit.com.au\/products\/ezarc-5pcs-countersink-drill-bit-set-for-metal-1-4-inch-hex-shank-countersunk-bits-82-degree-5-flute-1-4-3-8-1-2-5-8-3-4","provider":"SnaggIt","version":"1.0","type":"link"}
