The Tungsten material features high hardness, high strength, heat resistance, wear resistance, deformation resistance, and long-lasting performance.\u003c\/li\u003e\n\u003cli\u003eWith their precision-ground tips and enhanced rigidity, they ensure optimal hole quality, thereby enhancing the overall performance and reliability of the PCB.  The meticulous symmetry of these edges is great for promoting cutting actions and avoiding any lateral displacement during the drilling process.\u003c\/li\u003e\n\u003cli\u003eTungsten steel Carbide drill bit set is designed for PCB, CNC engraving and other high-precision hole required equipment, suitable for electronic boards, SMT, amber, hardware and other precision parts of the drilling process.\u003c\/li\u003e\n\u003cli\u003ePrecise alignment is critical. Use accurate guiding systems or fixtures to maintain straight drilling and prevent walking.\u003c\/li\u003e\n\u003cli\u003eApply lubricant, such as cutting oil or coolant, especially when drilling metal. This reduces friction, heat, and prolongs the bit's life.\u003c\/li\u003e\n\u003c\/ol\u003e\u003cbr\u003e","brand":"Harfington","offers":[{"title":"Default Title","offer_id":46446926889209,"sku":"a24050700ux1113","price":12.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/2477\/6095\/files\/ux_a24050700ux1113_ux_g03.jpg?v=1758160539","url":"https:\/\/www.harfington.com\/en-gb\/products\/p-1545881","provider":"Harfington","version":"1.0","type":"link"}
