Milwaukee SDS Plus Rotary Hammer Drill Bits

As a long-time DIY enthusiast and professional contractor, I've had the opportunity to use various brands and types of rotary hammer drill bits. Recently, I got my hands on the Milwaukee SDS Plus Rotary Hammer Drill Bits, model number 48-20-7930, and I must say, they left quite an impression.

Build Quality and Design

Right out of the box, the Milwaukee drill bits exude a sense of quality. The solid head carbide construction is immediately noticeable, providing a robust feel that suggests these bits are built to last. The inclusion of rebar guards is a thoughtful addition, aimed at enhancing durability, especially when drilling through reinforced concrete.

One of the standout features is the sharp centering tip. This design element ensures precise spot drilling, which is crucial for tasks requiring pinpoint accuracy. The variable flute design is another highlight, effectively aiding in faster dust removal. This not only improves the drilling efficiency but also extends the life of the bit by reducing wear and tear from accumulated debris.

Performance

The true test of any drill bit is its performance, and the Milwaukee SDS Plus bits do not disappoint. I used these bits to drill into a variety of masonry materials, including concrete with embedded rebar, brick, and even some old, hard aggregate. The bits performed exceptionally well in all these scenarios.

What struck me first was the ease with which these bits start drilling. Thanks to the sharp centering tip, there was no need for a pilot hole, even when using larger diameter bits. This saved a considerable amount of time and effort. The bits also showed no signs of drifting, ensuring that the holes were exactly where I needed them to be.

Durability

Durability is another area where these bits excel. The solid head carbide construction, combined with the rebar guards, means these bits can withstand the rigors of heavy-duty use. I drilled several holes into reinforced concrete and did not experience any chipping or dulling of the cutting edges. The wear mark indicator is a handy feature, letting you know when it’s time to replace the bit.

Versatility

These bits are designed to fit all SDS-Plus rotary hammers, making them a versatile addition to any toolkit. Whether you’re using a corded or cordless hammer drill, these bits engage securely and perform consistently. I used them with both a 12V and an 18V SDS drill, and in both cases, the bits performed flawlessly.

Case and Convenience

The bits come in a convenient carrying case, which is a nice touch. The case securely holds the bits in place and makes it easy to transport them to different job sites. The set includes a range of common sizes—3/16", 1/4", 5/16", 3/8", and 1/2"—covering most of the needs for concrete inserts and screws.

Value for Money

While these bits are not the cheapest on the market, they offer excellent value for money. The durability and performance justify the price, making them a worthwhile investment for both professionals and serious DIYers. The bits last significantly longer than other brands I’ve used, which ultimately saves money in the long run by reducing the frequency of replacements.
