Bosch 12 In. Bull Point Round Hex / Spline Hammer Steel Review
As an enthusiast in the world of power tools, I recently had the opportunity to test the Bosch 12 Inch Bull Point Round Hex/Spline Hammer Steel, model number HS1813. This tool is designed specifically for spline-drive demolition and rotary hammer applications, and I was keen to see how it performed in a real-world setting.

Straight out of the box, the Bosch Bull Point Chisel feels robust and well-made. The one-piece design is immediately noticeable, and it inspires confidence in its durability. Weighing it in my hand, it's clear that this tool is built to withstand heavy-duty tasks. The 12-inch length is substantial, providing ample reach and leverage for various demolition jobs.
Performance
Efficiency in Material Removal
One of the standout features of this chisel is its ability to remove large quantities of material efficiently. I used it primarily for breaking up concrete and brick, and it performed admirably. The tool's design allows it to penetrate and break apart materials with minimal effort. Each strike felt precise and effective, significantly reducing the time and effort required for demolition tasks.
Edge Retention
A crucial aspect of any chisel is how well it maintains its edge, and the Bosch Bull Point Chisel excels in this regard. After extensive use, the cutting edge remained as sharp as when it was new. This is particularly impressive given the demanding nature of the tasks I subjected it to. Edge retention is a testament to the quality of the steel used in manufacturing this tool, and it's clear that Bosch has invested in creating a durable product.

Durability is another area where this chisel shines. The one-piece design not only contributes to its strength but also eliminates potential weak points that could lead to premature failure. Throughout my testing, the tool showed no signs of wear or damage, even when subjected to rigorous use. This durability ensures that the Bosch Bull Point Chisel will be a reliable addition to any toolkit for a long time.
Design and Usability
Ergonomics
Using this chisel over extended periods was surprisingly comfortable. The balance of the tool is well-distributed, reducing user fatigue. The large spline shank fits securely into my rotary hammer, ensuring that there's no wobble or play during use. This secure fit translates to more efficient energy transfer from the hammer to the chisel, enhancing overall performance.
Versatility
While the primary use of this chisel is for demolition, its design allows for a range of applications. I found it equally effective for chipping away old mortar and removing stubborn tiles. The versatility of this tool makes it a valuable asset for various construction and renovation projects.
Value for Money
Considering the performance, durability, and versatility of the Bosch Bull Point Chisel, it offers excellent value for money. While there are cheaper options available, the quality and longevity of this tool justify the investment. It's a classic case of "you get what you pay for," and in this instance, you're getting a top-tier product that will serve you well for years to come.

Brutalist Concrete Planters
Turn broken slab pieces into sculptural planters. Use the bull point to fracture a concrete slab into controllable chunks, then peck out cavities for soil and drainage. The pointed tip lets you texture and chip the interior and rim for a raw, stone-like look. Seal inside, add gravel for drainage, and cluster pieces for a modern garden display.
Garden Bas-Relief Stele
Carve a standing garden stele from a concrete or stone blank. The bull point is ideal for roughing: mark your design, then chip away the background to leave a raised motif (leaves, abstract waves, house numbers). Finish with wire brushing and light acid wash to brighten aggregate. Mount on a small footing as a statement piece.
Split-Stone Fire Pit Blocks
Create rustic, flat-faced blocks for a fire pit or seating. Use the bull point to score and propagate controlled cracks on large fieldstones or salvaged curbs, splitting them into manageable faces. The faceted texture looks hand-hewn, and the 12-inch length gives reach and leverage for safe, precise blows with a rotary hammer.

Make wall art by fracturing a concrete paver or scrap to reveal colorful aggregate. Break into intentional shards, select pieces with attractive stone exposure, and arrange them on a backing board with construction adhesive or epoxy. The bull point’s controlled breaking gives you varied facets that catch light beautifully.
