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\n\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\n\u003cp\u003eThese drills have a 135° split point grinding tip which ensures perfect centring and reduced drilling pressure.\u003c\/p\u003e\n\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\n\u003chr\u003e\n\u003cp\u003eIrwin HSS Pro TiN Coated Drill Bit.\u003c\/p\u003e\n\u003cp\u003eSize 7.5 x 109mm.\u003c\/p\u003e","brand":"IRWIN®","offers":[{"title":"Default Title","offer_id":41913007669327,"sku":"TLB-IRW10502594","price":5.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2728\/6638\/files\/IRW10502585_f6d304a4-6c98-4598-89f8-91b4d9f887ef.jpg?v=1718037676","url":"https:\/\/us.gsworkwear.com\/products\/irwin-r-hss-pro-tin-coated-drill-bit-7-5mm-ol-109mm-wl-69mm","provider":"GS Workwear","version":"1.0","type":"link"}
