25-Piece HSS Cobalt Set

The Kango Cobalt Drill Bit provides improved drilling performance into stainless steel and hard metals. They are also suitable for drilling into timber and plastic. This set includes 25 Cobalt Drill Bits ranging in 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5,5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm and 13mm sizes. 

The Cobalt Drill Bit’s M35 5% cobalt blend is formulated to withstand extreme levels of heat and abrasion. Each tip has four cutting chamfers* to provide maximum material contact which delivers faster drill speeds and cleaner holes. Each tip also has a 135° split point which provides more stability and prevents the Cobalt Drill Bit from wandering.

With a tapered design, this Cobalt Drill Bit has a thicker and stronger base for preventing bit breakages. The rapid eject flute shape is efficient at ejecting chips and material which helps generate faster drilling speeds. The Cobalt Drill Bits sized 5mm and above, feature a 3-flat shank to prevent chuck slippage.

Available in-store and online from Bunnings Warehouse.
