Carbide Multi-Material Drill Bit - Shockwave - 1/8"

[This review was collected as part of a promotion.] Work as with tool experience for the house it's amazing I would recommend this tool for and job. Big or small I will be buying this product for tools and other products for my home business and my wife

[This review was collected as part of a promotion.] It's a drill-bit, drilled a few holes through some typical 2 x 4s and plywood for a self-help project and worked as expected. I have yet to have the opportunity to use it for any metal, concrete, etc.

I'll give it 2 stars just because it made it through 10 holes before completely dying, worked amazing first hole drilling on 4 month old slab by the way in 30° weather...

Broke the tip off on the 3rd hole. Figured the But would last longer. But I still like the Milwaukee tools.

[This review was collected as part of a promotion.] The 1/2" SHOCKWAVE™ Carbide Multi-Material Drill Bit appears to be a good quality bit. This bit is 1/2" diameter x 4” fluted x 6” overall length bit. It is similar in appearance and design to other masonry bits, but has two distinct differences. First, rather than the common round shank, this bit has a 1/4" hex shank which is potentially beneficial in two ways. The hex shank provides for improved grip and retention in the drill chuck, since the jaws should not easily slip on the flats of the hex shank. Additionally, the 1/4" hex shank fits the collet of 1/4" impact driver tools. The second difference that I observed is that the lands of the flutes are narrower and the grooves of the flute are wider than my other masonry and twist bits. I suspect that the wider grooves are designed to carry away and clear out more material, faster than typical masonry bits. The bit size is clearly stamped on the shank. I own and use Milwaukee hammer drills and impact drivers, including the outstanding M18 brushless tools which provide outstanding performance and are extremely powerful. This Shockwave bit can be used in both the drill and impact driver, however I generally use impact drivers to drive fasteners, and not to drill holes. I have used this bit for the brief time that I have owned it in my Milwaukee 2804 hammer drill, which is a powerful workhorse drill, and is the most powerful cordless hammer drill I have ever used. The Shockwave bit drilled into cured 2500 psi concrete, CMU block and 3000 psi grout just as expected. It drilled with reasonable speed and effort. The carbide tip appears to be sharp and the bit does a nice job of removing material and clearing the hole as drilling progresses. The Multi-Material design of the Shockwave bit is unique. Drilling wood and plastic was generally easy and effective, however, the carbide, masonry shaped tip of the bit does not have a point which is as sharp as a twist bit of the same size, which allows the Shockwave bit to drift more than twist bits when starting holes in metal, wood or plastic. The Multi-Material design is better put to use with stacked materials, rather than using it in place of a twist bit for starting holes in non-masonry materials. Where it proved useful and very effective, was when drilling through wood attached to masonry, such as drilling through bucks or ledger boards and into the masonry substrate. Of course, I need bits longer than this 4” bit for drilling holes for wedge anchors through 2”x wood bucks into block and/or cast concrete. Overall, I think that the Shockwave bit is a very good bit with a good design. It performs similarly to my other masonry bits. What remains unknown is the durability and longevity of the bit, as only time and use will reveal that. I expect drill bits to remain usable for a long time, and to continue cutting fast and well through the materials that they are intended for drilling into. Based on my experience with the Milwaukee Shockwave bit so far, I am optimistic that this bit will remain in my tool bag for a long time.
