GreenLee 36414 1-3/8" step drill bit


Buy at:

Used in:

Less expensive step bits are available but many are made of soft 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. 

*Not required if you are building from one of our control panel kits and you opted to have the enclosure pre-cut.
