Tired of bits that blunt too fast when you are pushing through tough metal alloys? At Wigley DIY, we know you need gear that works as hard as you do, which is why we stock the Irwin IRW10502580 HSS Pro TiN Coated Drill Bit - 3.5mm x 70mm. Built for tradespeople and serious DIYers tackling demanding drilling jobs, this 3.5mm x 70mm bit lets you boost your operating speed by 40 -60% and feed rate by 10 -20% without cutting short the working life of your tool.

Engineered from high quality HSS steel and finished with a hard-wearing Titanium Nitride coating, it reduces friction to save you power while diverting heat straight into your chips and coolant instead of your bit. With its self-centring 135? split point grinding tip, you get dead-on accuracy and less drilling pressure every single time you pull the trigger.

Features

• Designed primarily for drilling metal and harder, tougher alloys
• Allows speed to be increased by 40 -60% and feed by 10 -20% without significantly reducing drill bit life
• TiN is a poor conductor of heat, diverting generated heat into chips and coolant rather than the bit
• 135? split point grinding tip ensures perfect centring and reduced drilling pressure
• Body manufactured from high quality HSS steel coated with 2.5? Titanium Nitride (TiN)
• TiN coating has a hardness of app. 80 HRC and is very resistant to wear
• Low coefficient of friction results in less power consumed and less heat generated
