Compared to traditional HSS twist drill bits, speed can be increased by 40 -60% and feed by 10 -20% without reducing the life time of the drill bit significantly.\u003c\/p\u003e  \u003cp\u003eTiN is also a poor conductor of heat, so the heat generated during the drilling process is diverted into the chips and coolant and less into the drill bit.\u003c\/p\u003e  \u003cp\u003eThese drills have a 135° split point grinding tip which ensures perfect centring and reduced drilling pressure.\u003c\/p\u003e  \u003cp\u003eThe drill bit body is manufactured from high quality HSS steel coated with 2.5µ Titanium Nitride (TiN), the TiN coating has a hardness of app. 80 HRC and is very resistant to wear. TiN has a low coefficient of friction, this results in less power being consumed and less heat generated during the drilling.\u003c\/p\u003e\u003cp\u003eThe Irwin IRW10502580 HSS Pro TiN Coated Drill Bit comes in the following:\u003cbr\u003eSize: 3.5 x 70mm\u003c\/p\u003e","brand":"IRWIN®","offers":[{"title":"Default Title","offer_id":56169230565762,"sku":"IRW10502580-TOOLBANK","price":4.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0952\/2872\/3586\/files\/ed7f41bb-d501-4c28-a6de-092a4e9fc234.jpg?v=1767811239","url":"https:\/\/northantstrade.co.uk\/products\/irwin%c2%ae-hss-pro-tin-coated-drill-bit-3-5mm-ol-70mm-wl39mm","provider":"Northantstrade","version":"1.0","type":"link"}
