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\u003eIrwin HSS Pro TiN Coated Drill Bit.\u003c\/p\u003e  \u003cp\u003eSize 7.5 x 109mm.\u003c\/p\u003e","brand":"IRWIN®","offers":[{"title":"Default Title","offer_id":41388866896054,"sku":"TB-IRW10502594-01","price":1.75,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7054\/4566\/files\/irw10502585_26ecaec0-9299-4adf-96f1-8cded871759a.jpg?v=1704411258","url":"https:\/\/trade-mart.co.uk\/products\/irwinr-10502594-hss-pro-tin-coated-drill-bit-7-5mm-ol-109mm-wl-69mm","provider":"trade-mart.co.uk","version":"1.0","type":"link"}
