I almost exclusively use Bosch masonry bits when drilling holes for anchors to mount electrical panels or anchor strut to block walls. In my opinion they have the most diverse and best quality masonry bits on the market. Let’s dig into this SDS-Plus Carbide bit they sent me.

Functionality

What I first noticed about this carbide bit is that it has two distinct spiral designs over the length of the bit. The spiraling closer to the tip has 4 flutes that taper to two while the spiraling near the middle and rear of the bit is less aggressive and more consistent. The reason behind this is for removing material from the hole. A lot of standard masonry bits aren’t very good at removing particulate from the hole while you drill but this bit kicks a lot of material out while it drills because of this transitioned fluting.

The next thing to note is the shape and construction of the carbide tip. First off the entire tip is carbide as apposed to having only carbide teeth as some saw blades and bits do. The very center of the tip has a point, and the overall shape of the bit is conically designed to guide the bit through concrete better while leaving a more round hole in the wake.

Due to its diffusion bonding technology this bit is extremely rigid, and Bosch claims that it will last up to 4 times longer in concrete with rebar. The thing that sets the Xtreme Bosch bits apart from the regular carbide rotary hammer is the fluting at the front of the bit as well as the welding/brazing process used to create the tip. Normal bits are not as effective at removing material while drilling, nor are they as strongly welded at the tip. Other than that there’s not much of a difference.

Info from HomeDepot.com

The Bosch 1/2 in. x 10 in. x 12 in. Carbide X5L SDS-Plus Full-Head Hammer Drill Bit has a full-head carbide tip to enable faster drilling speeds and less wear. The centric conical tip guides the bit through concrete and provides rounder holes, while the flute design provides fast dust removal. Wear mark alerts you when the bit has worn to a level that is inappropriate for precision anchoring.

  • Full head carbide tip for faster drilling speeds and less wear

  • Diffusion bonding technology helps to create durable drill bits

  • Centric conical tip guides the bit through concrete and provides round holes

  • Flute design enables fast dust removal

Summary

This bit is a beast. I use these anytime I’m drilling through walls to pass romex (NM cable) through, or when I’m mounting large panels/enclosures to a concrete, block, or rock wall. Sometimes I need to build a strut rack on a concrete floor, and I’ll use it to anchor into the slab. I haven’t seen any competitor brands build anywhere near as quality of a product. 5/5 stars in my book.
