The Best Flex Bits for Electrical Work

Flex bits are long, flexible bits that come in handy when you need to drill through hard-to-reach materials, like through wood planks in ceilings or in walls. The long length of a flex bit enables you to drill a hole into spaced out pieces, like internal wall frames, and fish electrical wire through. If you’re looking for the best flex bits to use, here are some bits we recommend for you.

What to Look for in a Flex Bit

Here’s what to consider when buying flex bits:

• Length: Especially when you need to drill into multiple pieces at a time, the length of your bit will matter.
• Compatibility: Make sure your bit can connect to the drill you’re using.
