No matter the shape of the teeth, they’ll be made of either cast or forged metal. Because casting metal is less labor-intensive, it provides high cost-effectiveness. Manufacturers often cast teeth to be self-sharpening.
If you’re doing a variety of tasks with your machine, chisel teeth are a great choice. Chisel teeth specialize in providing good leverage for most loading and landscaping jobs. These are considered the “jack-off-all-trades” teeth. Unfortunately, chisel teeth don’t hold up well with more demanding jobs. Their penetration ability is modest, making them less than optimal for digging into stone and hard ground.
For more specialized jobs, single and twin tiger teeth provide the best penetration. Single tiger teeth come to a fierce point and look like a sharp tooth (hence the name). They provide more substantial penetration than chisel teeth. However, they have a lot of wear surface, meaning they have weaker wear resistance over time. Twin tiger teeth, as you might assume, fork out into two points. They have the strongest penetration of all chisel types, and because the work isn’t fixed on one point, they have a longer wear life than single tiger teeth. However, the trade-off for twin tiger teeth is less leverage for your machine.
When dealing with challenging surfaces, rock chisel teeth are your best bet. They provide excellent leverage and incredible wear resistance. These teeth are usually made with highly durable materials like alloy steel with molybdenum. They are self sharpening, meaning they won’t degrade over time like other types of teeth. Naturally, this efficiency usually comes at a higher cost.
Depending on the machine and the type of work you do, the perfect replacement teeth will be different. Getting the right kind for the job (and checking the size of the roll pin and shank) are crucial considerations. If you are unsure of which replacement teeth to get, contact DMC Wear Parts’ aftermarket specialists, and they will help you find the perfect fit for the job.
