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.

Best chew toy we have ever purchased.
Flavor Name: Classic, Size: Large
My moderately active 80lb Lab - Pit mix has been steadily working on this bone for over a year. He doesnt chew it every day but he does regularly chew it for 30 or more minutes at a time. He has only been chewing on the smooth end, and the only wear it shows is a slight thinning and some grooved tooth marks. It has not had any chunks come off, and has never developed any sharp edges that make it hard to play with. It has never smelled or gotten slimy. It has never triggered resource guarding with him, but he likes it enough that presenting it to him will often get him to settle down and chew when he is in a rambunctious mood. Its size and shape allows him to hold the textured Y end with his paws while chewing on the smooth end. All in all a fantastic toy!

Flavor Name: Beef, Size: Small
He immediately loved it. He doesn't take to bones quickly, but this one caught his eye. He's a 35 lb shepherd mix, and loves antlers, and chews pretty hard. I love that it doesn't smell, and havne't seen or noticed flakes. Overall would recommend.

Excellent product, highly recommend
Flavor Name: Classic, Size: Large, Flavor Name: Classic, Size: Large
So glad I came across this brand that uses actual edible material instead of the plastic nylon! All of our dogs love the nylon chew toys, but it's so bad for them to eat the little plastic bits! I got the large one & it is VERY large! I actually wish they had a medium one, one in-between the large & small ones as an option. But our dogs still love the large one, just harder for them to carry around & boy is it loud each time it gets dropped on the hardwood floor. It's big enough both the pups can chew on it together at the same time & do just that. We've had it for a couple months now & they don't chew on it everyday, but a few times a week I'd say & it's a tad bit softer than the nylon chews, but I'd say it's held up very well!
