Viking Norseman Vortex Point Step Drill Bits Sets Mechanic Length

These Vortex-Point drill bits cut 45% faster than conventional split point drill bits. The multi-stepped tip acts like a step drill which prevents walking on curved surfaces. and allows for laser straight holes in metal and other materials. This unique tip geometry requires less torque which creates less heat and thus increases tool life.

Constructed from special Hi-Molybdenum tool steel these bits stay sharp up to 4X longer than conventional and other specialty drill bit designs. 

The 135° split point allows for fast penetration, accurate and easy starting without a center punch. The precision ground point, flutes, body, clearance and drill diameter result in the ultimate in accuracy and performance.

They are perfect for enlarging existing holes without binding or grabbing as the bit exits the material. Plus, these bits virtually eliminate burrs and blowout on the exit side. 

The three-flatted shanks reduce slippage common with keyless chucks. Bits larger than 1/2" have 1/2" shanks with 3 flats

They are recommended for use with cast iron, brass, sheet metal, plastic, aluminum, mild steel, copper, hardened steel and even wood and composites.  They excel at drilling thinner and hardened metals.
