Milwaukee 9 Step Drill Bit 4.0 – 20.0mm
Milwaukee 9 Step Drill Bit for drilling copper, brass, aluminium, stainless steel, plastics, ferrous & non-ferrous sheets.
Spotdrill – Drill – Deburr – All in one go.
Due their stiffness they do not flex or wander on the material making them ideal for spot drilling, this also eliminates the need for pilot drilling.
Unique stepped design allows them to drill holes, – even large diameters, extremely quickly. The stepped drilling process prevents snagging and possible injury, also avoiding surface damage and material deformation. As the hole is enlarged step by step, strain is removed from the power tool – often increasing the machines drilling capacity.
Special geometry ground into the cutting edge deburrs automatically.
Manufactured from custom engineered steel with black oxide coating giving 4 x longer life.
Perfect for use with cordless drills.
Maximum material thickness 4mm – use of a coolant will increase the life of the product.
Size markings are laser engraved so they remain visible.
Tri shank to prevent any slipping when mounted in the chuck, also maintaining maximum torque transmission.
Repeatable specific diameter holes are easily achieved using the depth bar on your drilling machine.
