Milwaukee SDS Plus Rebar Cutter

Drilling through rebar can be a daunting task, but with the right tool, it becomes significantly more manageable. Recently, I had the opportunity to work with the Milwaukee SDS Plus Rebar Cutter (model number 48-20-6701), and I was keen to see if it lived up to its reputation. Here are my thoughts after putting it through its paces.

Design and Build Quality

Right out of the box, the SDS Plus Rebar Cutter feels robust. The tool boasts Milwaukee's HAMMER GUARD™ Shank, which is designed to protect the teeth from accidental hammer impacts. This feature is a thoughtful addition, especially since using a rotary hammer in the wrong mode could easily damage lesser tools. The red collar around the shank is a clear indicator and serves as a reminder to disable the hammer function when using this bit.

The cutter itself is crafted with precision-ground carbide, which Milwaukee claims improves drilling performance. The teeth are well-designed and spaced, with deep debris channels to efficiently remove rebar shards. Additionally, the double ejection slots make it easy to remove rebar slugs, which is a small but significant feature that enhances the overall user experience.

Performance

I first tested the SDS Plus Rebar Cutter on a piece of thick reinforced concrete. After drilling with a standard carbide-tipped drill bit until I hit the rebar, I switched to the rebar cutter. The transition was smooth, and the rebar cutter sliced through the metal with ease. The robust tooth design and precision-ground carbide really shine here, offering faster drilling speeds compared to traditional 4-cutter drill bits.

One of the immediate benefits I noticed was the minimal damage to the surrounding concrete. This is crucial for maintaining the integrity of the anchor points, especially in construction projects where precision is key. The cutter went through multiple pieces of rebar without noticeable degradation in performance, which speaks volumes about its durability.

Usability

Using the SDS Plus Rebar Cutter is straightforward, but there are a few tips to maximize its effectiveness. First, ensure that your rotary hammer is in drill mode and not hammer mode. The red collar acts as a handy reminder, but it's always good to double-check. Applying moderate pressure and occasionally clearing out debris—either by vacuuming or blowing—helps keep the drilling process smooth and prevents the bit from binding.

The tool's compatibility with all SDS-Plus rotary hammers adds to its versatility. I tested it with a couple of different models, and the performance was consistently excellent. Whether you're drilling into masonry, concrete, or even steel plates (with the appropriate cutting oil), this cutter handles the task efficiently.

Durability

Durability is where the Milwaukee SDS Plus Rebar Cutter truly excels. Over the course of several projects, the cutter maintained its sharpness and efficiency. The HAMMER GUARD™ Shank effectively protected the teeth from accidental hammer impacts, and the precision-ground carbide showed minimal wear even after repeated use. This is a tool designed to last, and it’s reassuring to know that it won’t need frequent replacements.

However, it's worth noting that proper usage is crucial for longevity. Using the cutter in the wrong mode or applying excessive pressure can lead to premature wear. Following the manufacturer’s guidelines can help you get the most out of this tool.

Cost vs. Performance

The SDS Plus Rebar Cutter is on the pricier side, but considering its performance and durability, it’s a worthwhile investment for professionals who frequently encounter rebar in their work. The time saved and the reduced wear on other drill bits make it a cost-effective addition to any toolbox. It's particularly beneficial for trades that spend considerable time drilling anchors in concrete, as the efficiency and precision it offers can significantly speed up the workflow.

Final Thoughts

In summary, the Milwaukee SDS Plus Rebar Cutter stands out as a high-quality, reliable tool for drilling through rebar. Its thoughtful design, including features like the HAMMER GUARD™ Shank and deep debris channels, enhances both performance and user experience. The precision-ground carbide and robust tooth design ensure faster drilling speeds and minimal damage to surrounding concrete, making it ideal for professional use.

Would I recommend the Milwaukee SDS Plus Rebar Cutter? Absolutely. The combination of durability, efficiency, and ease of use makes it a valuable tool for anyone working with reinforced concrete. While it does come with a higher price tag, the investment is justified by the time saved and the extended lifespan of the cutter. Just be sure to follow the usage guidelines to get the most out of this exceptional tool.
