Conquer Commercial Demolition with Pro-Grade Flat Chisel Punching Power

Supercharge your crew's productivity and maintain an unstoppable workflow on large-scale jobsites with the Bosch HS1912B10 18-Inch SDS-Max® Flat Chisel Bit 10-Pack. Engineered explicitly for commercial demolition contractors, mechanical teams, and masonry installers, these heavy-duty chisels concentrate your rotary hammer's kinetic shockwaves into a precision 1-inch flat cutting face. This linear geometry is highly effective for directional tracking, structural channeling for utility rough-ins, clearing tile and mortar, and systematically fracturing thick concrete slabs, foundation footings, and stone masonry walls. Purchasing this industrial bulk multi-pack ensures your jobsite fleet stays fully operational, minimizing tool-swap delays and keeping large construction deadlines safely on track.

Forged from a single piece of premium-grade alloy steel, each flat chisel in this commercial bundle is crafted to survive the most punishing cyclical impact forces. Bosch applies a proprietary, advanced thermal heat-treatment process that hardens the steel core to resist edge dulling while retaining proper core ductility to prevent catastrophic fracturing under extreme loads. The precision-machined universal SDS-Max® shank ensures a tight, wobble-free interface across all major heavy breaker hammer brands on the market, including Hilti systems utilizing TE-Y and TE-FY chuck configurations. Trust these Italian-forged heavy consumables to deliver optimized energy transmission straight to the work surface, generating clean fractures and rapid penetration rates day after day.

Key Features

  • 10-Piece Contractor Fleet Box: Provides high-volume construction and demolition crews an uninterrupted supply of heavy consumables across the jobsite.
  • 1-Inch Linear Cutting Edge: Delivers exceptional directional control for clean concrete trenching, localized slab channeling, and precise edge breakouts.
  • Universal SDS-Max Shank Fit: Precision-ground shank seamlessly slots into standard industrial SDS-Max hammers and Hilti TE-Y/TE-FY quick-change chucks.
  • Proprietary Heat-Treat Forging: Premium industrial alloy steel formulation engineered to combat structural fatigue and eliminate catastrophic bit breaks under load.
  • Monolithic One-Piece Construction: Eliminates welded joints or structural weak points, providing high impact energy transmission directly to the concrete.

  • (10) Bosch HS1912 1" x 18" SDS-Max® Heavy Duty Flat Chisel Bits

PRO-TIP: To preserve the straight profile sharpness of your flat chisel face, try starting your fractures by plunging at a slight 70 to 80-degree angle close to the edge of the concrete bed, instead of driving straight down into the dead center of an unbroken slab. Creating an adjacent air relief gap using this slight angle triggers clean spalling lines much faster and safeguards your tool from overheating or binding inside the masonry substrate!

Comfortable Shoes Right Out of the Box
Size: 9, Color: Black
I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

Paid for new, received used.
Size: 9.5 Wide, Color: Cognac, Size: 9.5 Wide, Color: Cognac
Arrived dirty as if someone whore it for more than a few days. Maybe I was mistaken, but I saw nothing about “previously used” on the Amazon page. Returned it. I would suggest that the company use quality control when it comes to shipping. The shoes seem find otherwise. I ordered 9.5 and it was just a bit tight. If I reorder I will go for size 10.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
