Walk It Out

The new Diablo Step Bits feature a 132° split point tip that digs into thin metals and PVC quickly. It starts drilling where you place the bit without walking around the surface of the material first. Since it eliminates the need to pre-drill your material (when you need consistency and accuracy) we find this an important feature.

Diablo Step Bits

Diablo claims that, because these bits manage fast on-point starting, their product should last longer than many other step bits on the market.


Undoubtedly, some of this additional lifespan can be chalked up to how they manufacture these bits. Diablo uses an automated precision CNC grinding process that delivers strict angle tolerances on each step for minimal bit wear and fast cutting.

This unique design delivers better corded and cordless tool efficiency as well. In high-speed, they claim Diablo step bits get up to 75% more holes drilled per battery charge.

Features

The Diablo Step Bits feature a 1/4″ hex shank to work with just about any drill or impact driver. The one exception falls to the 1-3/8″ step bit which uses a 3/8″ shank with three flats. It also has a dual flute design for jam-free cutting.

As far as the steps go, Diablo has laser marked the steps for easier reading. They even included solid black bars to denote common sizes. We LOVE this as they remain very visible while drilling. Also, some of the various models feature increased step heights for easier drilling of common hole sizes.

A Variety of Options

The Diablo step bits come in a few various sizes and configurations. You can pick up a 1/2″ (in either 6-step or 13-step configurations), 3/4″, 7/8″, 1-1/8″, and 1-3/8″ diameter. They range in price from about $20 to $50.
