{"product_id":"irwin-hss-pro-tin-coated-drill-bits","title":"Irwin HSS Pro TiN Coated Drill Bits","description":"\u003cp\u003eThese HSS Pro TiN twist drill bits are primarily designed for drilling metal and harder, tougher alloys, also making them suitable for hard and soft woods, manmade boards and plastics. 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","brand":"Irwin","offers":[{"title":"1.0 mm \/ 34 mm 12 mm \/ 2","offer_id":54118836011355,"sku":"113946","price":0.84,"currency_code":"GBP","in_stock":true},{"title":"1.5 mm \/ 40 mm 18 mm \/ 2","offer_id":54118836044123,"sku":"113947","price":0.84,"currency_code":"GBP","in_stock":true},{"title":"2.0 mm \/ 49 mm 24 mm \/ 2","offer_id":54118836076891,"sku":"113948","price":0.97,"currency_code":"GBP","in_stock":true},{"title":"2.5 mm \/ 57 mm 30 mm \/ 2","offer_id":54118836109659,"sku":"113949","price":1.07,"currency_code":"GBP","in_stock":true},{"title":"3.0 mm \/ 61 mm 33 mm \/ 1","offer_id":54118836142427,"sku":"113950","price":1.07,"currency_code":"GBP","in_stock":true},{"title":"3.5 mm \/ 70 mm 39 mm \/ 1","offer_id":54118836175195,"sku":"113951","price":1.13,"currency_code":"GBP","in_stock":true},{"title":"4.0 mm \/ 75 mm 43 mm \/ 1","offer_id":54118836207963,"sku":"113952","price":1.31,"currency_code":"GBP","in_stock":true},{"title":"4.5 mm \/ 80 mm 47 mm \/ 1","offer_id":54118836240731,"sku":"113953","price":1.36,"currency_code":"GBP","in_stock":true},{"title":"5.0 mm \/ 86 mm 52 mm \/ 1","offer_id":54118836273499,"sku":"113954","price":1.45,"currency_code":"GBP","in_stock":true},{"title":"6.0 mm \/ 93 mm 57 mm \/ 1","offer_id":54118836306267,"sku":"113955","price":1.68,"currency_code":"GBP","in_stock":true},{"title":"6.5 mm \/ 101 mm 63 mm \/ 1","offer_id":54118836339035,"sku":"113956","price":1.91,"currency_code":"GBP","in_stock":true},{"title":"7.0 mm \/ 109 mm 69 mm \/ 1","offer_id":54118836371803,"sku":"113957","price":2.11,"currency_code":"GBP","in_stock":true},{"title":"8.0 mm \/ 117 mm 75 mm \/ 1","offer_id":54118836404571,"sku":"113958","price":2.84,"currency_code":"GBP","in_stock":true},{"title":"8.5 mm \/ 117 mm 75 mm \/ 1","offer_id":54118836437339,"sku":"113959","price":3.0,"currency_code":"GBP","in_stock":true},{"title":"9.5 mm \/ 125 mm 81 mm \/ 1","offer_id":54118836470107,"sku":"113960","price":3.49,"currency_code":"GBP","in_stock":true},{"title":"10 mm \/ 133 mm 87 mm \/ 1","offer_id":54118836502875,"sku":"113961","price":3.91,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/0652\/0667\/files\/113955_xl.jpg?v=1789792829","url":"https:\/\/www.axminstertools.com\/products\/irwin-hss-pro-tin-coated-drill-bits","provider":"Axminster Tools","version":"1.0","type":"link"}
