Milwaukee SDS-PLUS Thin Wall Carbide Tipped Core Bit

Drilling through concrete, brick, and block walls can be a daunting task without the right tool. Recently, I had the chance to put the Milwaukee SDS-PLUS Thin Wall Carbide Tipped Core Bit to the test on a variety of masonry projects. As someone who frequently tackles these kinds of jobs, I was eager to see how this core bit would perform.

One of the first things I noticed about this core bit is its thin wall design. This feature is particularly useful when you're looking to minimize the amount of material removed, which in turn reduces the effort and time required for the job. The 1-1/2 inch diameter is versatile enough for most common applications, and the usable cutting depth of 3-3/16 inches is more than adequate for many through-hole tasks.

The core bit comes with a guide plate and centering pin, which are essential for maintaining accuracy during drilling. The inclusion of these components ensures that the bit stays on target, reducing the chances of wandering and making the drilling process much smoother. I found these additions particularly helpful when working on more precise applications, such as installing anchor bolts or running conduit through walls.

One standout aspect of this core bit is its compatibility with both 8-inch and 12-inch SDS PLUS adapter shanks. This flexibility allows you to choose the appropriate shank length for your specific needs, whether you're drilling a shallow hole or a deeper one. Additionally, the bit can be used with a 7-1/2 inch extension, which is a nice touch for those harder-to-reach areas.

In terms of performance, the Milwaukee core bit did not disappoint. I used it on a variety of materials, including concrete floor tiles and a 6-inch slab foundation wall. In both cases, the bit performed admirably, cutting through the material with ease and efficiency. The carbide tips are durable and designed to handle the rigors of masonry drilling, and they showed no signs of dulling even after multiple uses.

One of the most significant advantages of this core bit is its German manufacturing. As anyone in the trades knows, German-made carbide bits are often synonymous with quality and reliability. This bit lived up to that reputation, delivering consistent performance and durability throughout my testing.

However, it's worth noting that this core bit is sold as just the core bit itself. You'll need to purchase an SDS-Plus thin-wall core bit shank adapter separately. While this isn't a major inconvenience, it's something to keep in mind when budgeting for your tools.

I did encounter a minor issue with removing the drill from the mandrel. It required a bit more effort than I would have liked, but it wasn't a deal-breaker. Additionally, while the bit performed well in most scenarios, it did struggle a bit when encountering rebar. This is a common challenge with many masonry bits, and it's always a good idea to avoid drilling through rebar whenever possible to prolong the life of your bit.

In terms of longevity, the bit held up well during my testing. I used it on multiple CMU (concrete masonry unit) walls, and it remained sharp even after drilling 15 cores. This level of durability is impressive and speaks to the quality of the carbide tips and overall construction of the bit.

One area where the bit could improve is its price point. While it's not the cheapest option on the market, the performance and durability it offers do justify the cost to some extent. For professionals who need a reliable and efficient core bit for frequent use, the investment is likely worth it. However, for occasional DIYers, the price might be a bit steep.

In conclusion, the Milwaukee SDS-PLUS Thin Wall Carbide Tipped Core Bit is a robust and reliable tool for drilling through masonry materials. Its thin wall design, compatibility with various shank lengths, and German manufacturing make it a standout choice for professionals in the trades. While it has a few minor drawbacks, such as the need for a separate shank adapter and some difficulty with rebar, these are relatively minor issues in the grand scheme of things.

I would recommend this core bit to anyone who frequently works with masonry materials and needs a dependable, high-performance tool. Its durability and efficiency make it a worthwhile investment for professionals, and its versatility ensures it can handle a wide range of applications. If you're looking for a core bit that can deliver consistent results and withstand the rigors of regular use, the Milwaukee SDS-PLUS Thin Wall Carbide Tipped Core Bit is an excellent choice.
