Cut Precise Joint Grooves and Clean Narrow Channels in Commercial Poured Concrete and Masonry Structures with Forged Slotting Steel

Transform your masonry remediation and layout channelling efficiency with the professional-grade Bosch 1-1/8 Inch Width x 15 Inch Length Slotting Tool Round Hex/Spline Hammer Steel. Specifically engineered for commercial electrical contractors, industrial plumbing crews, structural restoration teams, and waterproofing specialists, this premium slotting bit provides unmatched control over targeted demolition. Standard masonry chisels feature flat edges that scatter fracture lines randomly, often cracking adjoining structural surfaces and leaving messy paths during joint repair work. This heavy-duty structural slotting tool resolves that field bottleneck by introducing an optimized narrow, concave wedging face that concentrates kinetic impact waves perfectly to track straight, carving crisp lines for conduit installation, pipe routing, or structural expansion joint cleaning.

Forged in Italy from high-stress structural alloy steel, this durable 15-inch monoblock tool benefits from an exclusive, proprietary thermal heat-treating process that tempers the metal core matrix to absorb intense continuous mechanical shock. This specialized structural composition translates the high-velocity percussion output of your combination hammer tools straight down the axis of the shaft, avoiding lateral flex and preventing premature mid-body fractures under continuous heavy loads. Engineered to plow through high-psi poured concrete, dense block backings, mortar seams, and hard aggregate building brick, this narrow gouging profile lets operators make surgical breakthroughs inside tight foundational corners. Complete with a universal round hex and spline combination shank that slides smoothly into heavy-duty chipping hammer tools, this commercial slotting bit guarantees precision and clean track paths shift after shift.

Key Features

  • Targeted 1-1/8 Inch Cutting Face: Narrow structural head profile concentrates impact force to gouge sharp, uniform channels without cracking surrounding walls.
  • Proprietary Heat-Treat Engineering: Advanced computer-controlled thermal matrix tempering maximizes alloy steel density to stop structural bit failure.
  • Monoblock One-Piece Forging: Streamlined solid core architecture transmits percussive impact waves smoothly, eliminating torque deflection.
  • Precision Joint Restoring Index: Tailored specifically to achieve straight tracking during deep mortar joint clearing, expansion slotting, and structural cracks.
  • Universal Spline / Round Hex Fit: Slotted multi-fit shank connection engages mechanically inside all standard combination rotary hammer tools.
  • Low-Friction Profile Alignment: Tapered cutting edges direct pulverized stone dust outward, preventing the tool head from binding inside deep slots.

Pro-Tip: When cutting deep tracking channels with this 15-inch slotting bit, avoid driving the narrow chisel tip directly straight down at a hard 90-degree angle. Lean your spline chipping gun at an angled 45 to 60-degree pitch along your layout line. This lets the curved nose of the slotting tool act as a gouge, continuously rolling cracked concrete chips out of the trench track rather than packing fine stone dust into the base and trapping the bit head.

Cheap and good
Color: Black, Color: Black
I chose the color black and it gives a really nice look, especially with the multicolor led lights around the keys. It is very easy to clean and you can shut off the keyboard to prevent any mess with the iPad. The magnet is very nice and keeps the keyboard in place. The keyboard doesn’t easily slip or anything so it holds the iPad very well. Only bad thing is that over time the iPad begins to scrape off the pain and it leaves your keyboard with some white spots all over :/ but if looks isn’t something that you care about, this is the keyboard for you. Don’t use it for gaming because there is a delay in functionality when you press a key and then try to use the pad. Also, you have to press the keys a bit harder than the usual keyboard. But for the price? This is a great item! Definitely worth my money

Great quality at a remarkable price
Color: Navy Blue
I got an iPad and was looking for a cover to protect it. I came across this case that has a Bluetooth keyboard. It seems to be working great. It was less than $30 and had 4.5 stars with over 4k reviews. The keyboard is magnetic and detachable, so I’ve got lots of configuration options. The keyboard pairs easily and allows you to use the iPad like a laptop. The point of an iPad a lot in one shot is kind of the touchscreen, but when I’m typing a lot of text as once (like now), it’s really nice to have a physical keyboard and touchpad. The keys are comfortably spaced and I’m comfortable typing on it. There is no additional setup for the keyboard besides pairing it to the iPad. At that point, all the cursor and keyboard features are immediately available. The case is well built and has nice features like a slot to hold a stylus and multiple grooves to set your viewing angle. It’s configured to be used in landscape mode, but if for some reason you wanted to use it in portrait mode, you can pop the keyboard off to lay it flat. Especially for the price, this is an exceptionally nice iPad cover.
