Shield machine propulsion bit

Shield machine propulsion bit

Maruwa Bit has built a track record at various construction sites! We provide products tailored to our customers' needs.

We would like to introduce the "shield machine and thrust machine bits" that we handle. In recent years, as long-distance excavation has been in demand, we have been focusing on the development of products that excel in wear resistance and impact resistance, as well as developing bits suitable for a circular economy. We also engage in the reuse and recycling of bits and carbide tips. Please feel free to contact us if you have any requests. 【Features】 ■ Focus on the development of products that excel in wear resistance and impact resistance ■ Also developing bits suitable for a circular economy ■ Engaging in the reuse and recycling of bits and carbide tips *For more details, please refer to the PDF materials or feel free to contact us.

A must-see for those looking for the right size of carbide drill bits!

A must-see for those looking for the right size of carbide drill bits!

If the size of the carbide claws attached to the excavation machine is too large and gets caught in the ground, a specially shaped bit that reduces the body size of the claws and decreases impact resistance is effective.

In drilling bits, inappropriate claw shapes can create shock resistance, which may lead to a decrease in the drilling performance of the machine itself. To fully utilize the tool's performance, it is necessary to consider optimal shape design to reduce the overall shock resistance of the tool and the brazing position of the carbide part that will be subjected to action. In cases where the tool is welded to the machine body, if the welding position is too close to the brazing position, there is a risk of tool defects due to reduced brazing strength caused by the heat during welding. In other words, the shape of the carbide part and the brazing position become important points. For more details, please refer to the "Processing Technology Special Feature."
