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 IRW10502573 HSS Pro TiN Coated Drill Bit comes in the following:\u003cbr\u003eSize 1.5 x 40mm.\u003c\/p\u003e","brand":"IRWIN®","offers":[{"title":"Default Title","offer_id":54179950330241,"sku":"IRW10502573-TOOL","price":6.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0114\/3049\/4272\/files\/4fdb6ac8-aa3e-47d8-8f2b-594bff716c35.jpg?v=1743188035","url":"https:\/\/nn4online.co.uk\/products\/irwin-r-hss-pro-tin-coated-drill-bits-2-1-5mm-ol-40mm-wl-18mm","provider":"NN4 Online ","version":"1.0","type":"link"}
