Milwaukee 3/8" x 18" Bellhanger Bit

As a professional who frequently tackles installations requiring deep drilling or running wires through walls, I often find myself on the lookout for tools that can simplify the job. The Milwaukee 3/8" x 18" Bellhanger Bit caught my eye due to its specialized design and features tailored to these specific tasks. Having put the bit through its paces in a variety of scenarios, I’ve gathered some insights that may help you decide if this tool belongs in your kit.

Build and Design

Milwaukee is a brand synonymous with quality, and the Bellhanger Bit doesn't disappoint in its construction. The bit is 18 inches long, offering ample reach for most applications, whether you’re drilling through thick walls or needing that extra length for deep holes. The 3/8" diameter is versatile enough for a variety of installations, from pulling wires for security systems to running cables for home theaters.

One standout feature of this bit is the pull-through hole at the tip. This design element is intended to make wire installations straightforward by allowing you to attach and pull small wires through the hole you just drilled. The bit also features aggressive tip geometry and coated flutes, which promise fast cutting and efficient chip removal. The 3-Flat Secure-Grip™ shank is another thoughtful addition, ensuring the bit doesn't slip in the drill chuck, a common issue with round shanks.

Performance

In terms of performance, the Bellhanger Bit has its highs and lows. When drilling through standard materials like drywall, flooring, and untreated wood, the bit performs admirably. It cuts smoothly and quickly, living up to the manufacturer’s claims about its aggressive tip geometry. The coated flutes do an excellent job of removing chips, preventing clogging and ensuring a cleaner, faster drilling process.

However, the bit does struggle a bit when it comes to harder materials. Drilling through treated lumber or hitting a brick wall can slow the bit down considerably. The bit is not as sharp as I would have hoped, and there were instances where it took a frustratingly long time to get through a 2x4. For those working with harder materials frequently, this might be a significant drawback.

Durability

Durability is another mixed bag with this tool. For many users, the bit has proven to be sturdy and long-lasting, capable of multiple uses without significant wear. I found it robust enough for most of my tasks, but there were instances where the bit didn’t hold up as well as expected. For example, drilling through treated posts seemed to wear the bit down faster than anticipated, and in one unfortunate instance, the bit actually broke before I could finish the job.

Usability

The pull-through hole is a brilliant idea in theory, but it does have some limitations. The hole size is quite small, which can be a problem when trying to pull thicker wires or tubing. I had to improvise with smaller gauge wires when my standard 14GA copper ground wire couldn’t fit through the hole. This added an extra step to the process and some inconvenience.

On the positive side, the 3-Flat Secure-Grip™ shank works exceptionally well. I never experienced any slippage in the drill chuck, which is a huge plus when drilling deep holes. The bit comes in a durable package that can double as storage, keeping the bit safe and secure when not in use.

Cost

Price-wise, the bit is a bit on the higher side compared to its competitors. While the quality justifies the price to some extent, it might feel a bit steep, especially if you encounter durability issues or need to replace it sooner than expected. However, when you consider the convenience and the specific design tailored for wire installations, the cost might be justifiable for professionals who frequently need to run wires through challenging spaces.

Final Thoughts

The Milwaukee 3/8" x 18" Bellhanger Bit is a solid choice for specific tasks, particularly for those who need a reliable tool for running wires through walls and other deep drilling applications. Its standout features, like the pull-through hole and the 3-Flat Secure-Grip™ shank, make it a convenient tool to have on hand.

However, its performance on harder materials and some durability concerns are worth noting. If your work primarily involves drilling through standard building materials and you need the specialized features this bit offers, it’s a worthwhile investment. On the other hand, if you often find yourself drilling through tougher materials, you might want to consider other options or have a backup bit on hand.

In conclusion, I would recommend the Milwaukee Bellhanger Bit for its specific use case in wire installations and for professionals who value convenience and thoughtful design. Just be mindful of its limitations and ensure it aligns with your primary drilling needs.
