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.

Puppy loves these sticks!
Color: Dogwood & Calming, Size: Medium
Dogs love these sticks! Must smell and taste like real wood because it keeps my puppy from bringing real sticks in the house from outside. She is a heavy chewer and these sticks keep her occupied. We are on our 2nd set.

Our dog loves it but it wasn’t durable enough to last
Color: Dogwood Jack, Size: Large, Color: Dogwood Jack, Size: Large
Our lab took to it as soon as we gave it to her. Perfect size for our 80 lb yellow lab. However, now that it’s in about 10 days, she’s able to break off chunks from this bone that are dime size or larger, and we have to throw it away

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long. I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do. I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.
