GreenLee 36414 1-3/8" step drill bit
*Not required if you are building from one of our control panel kits and you opted to have us pre-punch the enclosure for you.
Less expensive step bits are available but many are made of softer metal which does not cut as well and can damage the item you're drilling. We highly recommend the GreenLee 36414 (shown in the picture) to avoid any possible issues, especially when drilling into kettles.
