The Professional Cable Solution: IRWIN Installer Bit for Fast, Clean Wood Boring

The IRWIN 3/8" x 18" Wood Installer Drill Bit is a specialized tool engineered for the demanding task of routing cable and wire through finished walls, ceilings, and floors. This extra-long bit provides the necessary reach (18 inches) to bore through multiple studs or joists, making it indispensable for electricians, low-voltage technicians, and remodelers. The primary time-saving feature is the hole located in the flute, which allows for the cable or wire to be easily attached and pulled back through the bore hole as the bit is withdrawn, streamlining the entire installation process.

Performance and durability are built into every detail. The bit features a robust 3-flatted shank that locks securely into the drill chuck, effectively preventing slippage and maximizing power transfer. The aggressive 82-degree point is designed for fast, smooth drilling into wood without walking or wandering, ensuring accurate hole placement every time. Constructed from high-carbon steel, this installer bit delivers the longevity and reliability required for continuous use across demanding construction and home renovation projects.

Key Features

  • Specialized Wire Pulling Hole: Hole in the flute allows for quick and easy pulling of wire, cable, or chain through drilled cavities.
  • Extra-Long Reach: 18-inch length is ideal for routing through multiple studs or joists in walls and ceilings.
  • 3-Flatted Shank: Design prevents the bit from slipping in the drill chuck, ensuring maximum drilling stability.
  • 82-Degree Point: Provides a sharp, aggressive tip for fast, smooth starts and reduced bit walking in wood.
  • Durable Construction: Made from high-carbon steel for strength and reliable performance.

Pro Tip: Before withdrawing the bit from the drilled hole, securely feed your wire, cable, or pull chain through the flute hole at the tip. As you pull the bit back through the wall cavity, the bit guides the wire safely through the newly created channel, drastically simplifying the process of running new wires without snags or damage.

Fantastic Product
I bought these hangers to mount my speakers. They are heavy duty, has a curl at the end to keep the speakers from falling off, and I was able to mount them and have clearance underneath. Awesome!!

Does it's purpose with style
We used these in our pantry and dining room for shelves and they turned out well. The only reason they are hard to install is because of the design (which is very nice) so it is worth it. It just takes time when you you are hanging the shelves, to do it correctly. While they can hold a lot, we realized that a bunch of cans or jars cannot go on these shelves. Luckily we had another option for heavy items (Example: We had about 40ish pounds of cans/jars on a 1x12 board that is 33 inches long with 2 of these brackets...and it was too much). If you do not need to hold a lot of weight, these shelves are a for sure, for the price and quality. If you NEED they for something heavy, then you probably will have to go with something more practical from a hardware store. We LOVE them for our pantry!

Worked as intended
Hubby used these to mount a shelf above a long span of windows. They worked great and allowed a clean visual appearance.

Nice brackets
These are nice sturdy brackets for butcher block shelf however they do bend a bit. We installed in a corner so was able to pin to side wall no problems on big shelf. The smaller shelf about 18” moves a bit up and down when loading. Now very little and no worries about it but not rock solid
