Maximize Mass Demolition Yields with Industrial-Grade Bull Point Chisel Power

Tackle large-scale concrete chipping and structural break-up jobs with the Bosch HS1813B20 12-Inch Spline Shank Rotary Hammer Bull Point Chisel Bit 20-Pack. Designed specifically for mechanical tradesmen, pool builders, utility contractors, and commercial demolition teams, these high-impact bull point points specialize in localized stress fracturing. By channeling your rotary hammer's complete impact force straight into a sharp, focused tip, these chisels easily shatter dense unreinforced concrete, heavy foundation slabs, masonry brick configurations, aggregate blocks, and structural grout lines. Buying this multi-pack guarantees your fleet stays completely outfitted on high-production construction projects, eliminating costly jobsite interruptions.

Engineered to withstand brutal continuous cyclic shock, each chisel in this bulk kit is manufactured from a single piece of premium-grade forged alloy steel. Bosch implements a proprietary, advanced thermal heat-treatment process that hardens the carbon-steel core to significantly resist tip dulling while maintaining structural ductility to eliminate catastrophic shattering under high trade loads. The universal 3/4-inch hex by 21/32-inch round spline shank profile delivers a rock-solid, non-slip interface for conventional spline-drive demolition hammers and large rotary hammers. Trust these Italian-made heavy-duty consumables to track accurately, clear hard masonry substrates at rapid penetration rates, and deliver reliable jobsite durability to your commercial crews.

Key Features

  • 20-Piece Bulk Fleet Pack: Keeps heavy construction and demolition teams continuously supplied across large-scale commercial job sites.
  • Concentrated Point Geometry: Directs your tool's maximum joules of impact force to a single point, allowing for fast starting holes and mass fracture runs.
  • Universal Spline Shank Fit: Precision-ground 3/4" hex x 21/32" round shank matches standard professional spline-drive demolition and rotary hammer chucks.
  • Proprietary Heat-Treat Forging: Premium industrial alloy steel formulation engineered to combat structural fatigue and eliminate catastrophic bit breaks under load.
  • One-Piece Core Structural Balance: Forged from a single piece of premium steel to transfer kinetic energy efficiently without dampening vibrations.

PRO-TIP: Bull point chisels are explicitly meant for initiating deep fault cracks and breaking bulk chunks of stone or unreinforced slabs. Avoid using them to pry or lever concrete beds like a crowbar once the tip is driven down! Relying on mechanical prying forces puts excessive lateral stress across the bit throat, which can strain your tool's spline retainer chuck and crack even high-tensile heat-treated alloy steel shanks!

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.

Good deal for the price
Style: 80 mil 18 SqFt
The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil
