Evolution Step Drills



Evolution Premium Step Drills are made from the same high quality M2AL as Cyclone Premium Annular Cutters. These tools are heat treated to 68RC, giving them more durability during tough applications.

Evolution Premium Step Drills are used to produce a range of hole sizes in steel up to 1/8" thick using only one tool. The twin flute design allows for a smoother cutting action with no pre-drilling necessary. Evolution Premium Step Drills have 3 chucking flats on the driving shank to ensure no slipping in the chuck.

Blades.

CUT SAFER:

When cutting metals, Evolution blades leave an instantly workable finish and produce virtually no heat, burrs or sparks. This allows the material cut to be handled quickly instead of having to wait for the metal to cool down, as required with abrasives. Abrasive blades can create excessive dust, fumes, smoke, fire and can even explode.

CUT FASTER:

Evolution blades cut faster than traditional abrasive blade methods. An Evolution mild steel blade can cut through 6" of 1/4" thick mild steel plate, in as little as 12 seconds*.

CUT SMOOTHER:

Abrasive blades tend to flex and "walk" during a cut. Evolution blades are designed for accuracy and precision. The cuts are cleaner, leaving an instantly workable, smooth finish.

CUT LONGER:

Abrasive blades wear down quickly. This reduces both cut quality and cut capacity depth. It also increases the costly replacement of abrasives required to complete the job. Unlike abrasives, Evolution TCT blades maintain quality and capacity throughout, saving time and money!
