Specially Designed for drilling stainless steel. Universal round shank for easier clamping and stable cutting process.\u003c\/li\u003e\n\u003cli\u003eGold titanium and black nitride dual coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular black surface. High-speed steel tools have high hardness, good toughness, high wear resistance. \u003c\/li\u003e\n\u003cli\u003eWidely used for drilling stainless steel, aluminum alloy, iron, copper, wood and plastic. Suitable lubricant is conducive to cutting or cooling, making cutting easier and improving smoothness, dimensional accuracy, and extending the service life. Used on electric hand drill, drilling machine and bench drill.\u003c\/li\u003e\n\u003cli\u003eSharp spiral flutes provide neat and smooth cuts. High cutting edge strength, fast cutting speed. Spiral groove facilitates the export of metal chip, saving time and effort in operation. Common flute and overall length for minimal adjustment during tool changes.\u003c\/li\u003e\n\u003cli\u003eWhen using hand-held electric drill, the recommended speed is 100-1000rpm\/min; the larger the drilling diameter, the slower the drilling speed. Drill metal with high hardness or foreign substance, the rotational speed should be slower than normal drilling.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"uxcell","offers":[{"title":"Default Title","offer_id":46796178391289,"sku":"f22031800ux0049","price":21.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/2477\/6095\/files\/ux_f22031800ux0049_ux_g03.jpg?v=1775403614","url":"https:\/\/www.harfington.com\/en-au\/products\/p-1829251","provider":"Harfington","version":"1.0","type":"link"}
