{"product_id":"p-1516911","title":"10pcs 2.85mm PCB Drill Bits Carbide CNC Engraving Micro Twist Drilling Tool","description":"\u003col\u003e\n\u003cli\u003eThe tip drill bit adopts a spiral flute design, mirror polishing. It can discharge chips and waste generated by cutting more effectively, reduce cutting resistance and heat accumulation, improve cutting speed and work efficiency, and reduce vibration and noise, maintain the cutting process's stability.\u003c\/li\u003e\n\u003cli\u003eThis mini twist drill bit is made of solid carbide, which has the characteristics of high hardness, high strength, strong wear resistance, good corrosion resistance, and excellent thermal stability. These properties allow the drill to maintain consistent cutting capabilities and a long service life—without worrying about breakage or deformation.\u003c\/li\u003e\n\u003cli\u003eThe surface treatment of titanium coating has a low friction coefficient, which can reduce friction and wear during cutting; the tool surface is smooth and has strong anti-adhesion and good self-lubricating properties, which helps to improve the quality of the cutting surface smoothness and machining accuracy, improving cutting quality.\u003c\/li\u003e\n\u003cli\u003eThe drill bit has a precision cutting edge to maintain smooth cutting; it is designed with a positioning ring to easily achieve accurate positioning while enhancing the stability and shock resistance of the drill bit; the cutting shank adopts a chamfer design, which has high precision and can reduce installation and debugging time.\u003c\/li\u003e\n\u003cli\u003ePCB drill bit is for the precision processing of jewelry, printed circuit boards, plastics, fiberglass, acrylic, wood, soft metals and other materials, suitable for PCB drilling machines, CNC engraving machines and high-precision special drilling equipment.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"uxcell","offers":[{"title":"Default Title","offer_id":47295533678841,"sku":"a24040900ux0473","price":16.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/2477\/6095\/files\/ux_a24040900ux0473_ux_g03.jpg?v=1769204795","url":"https:\/\/www.harfington.com\/en-gb\/products\/p-1516911","provider":"Harfington","version":"1.0","type":"link"}
