Irwin Turbomax HSS Drill Bit

The 8.5mm Irwin Turbomax HSS Drill Bit measures 8.5 x 117mm, offering an intermediate size that's particularly useful for specific engineering tolerances and clearance applications. This diameter is ideal for creating clearance holes for M9 fixings or where precise 8.5mm dimensions are required. Designed for portable and cordless drills, this bit is primarily engineered for drilling metal and sheet metal, whilst also delivering excellent performance in all types of wood and plastics. The 117mm overall length provides enhanced reach for deeper drilling operations and thicker materials, making it suitable for demanding fabrication tasks. It can be used for drilling stainless steel, though a coolant should always be used to maintain optimal cutting performance and bit longevity.
