IRWIN® HSS Pro Titanium 13 Piece Drill Bits are designed for drilling metal and harder alloys, as well as being able to produce increased drill speeds of 40-60% in comparison to the standard bits. With a titanium nitride coating, the drill bits offer higher friction resistance and longer life. Their 135° split point ensures perfect centring and minimises bit walk, while also reducing drilling pressure, giving a more accurate and clean finish. Heavy-duty web construction is designed to optimise strength and durability of the drill bits.
The team at McCormick are great and responded quickly and efficiently with my order. If I were them though I might consider using a different delivery company
