Grundomat Stepped Cone – Replacement Stepped Cone for Grundomat Piercing Tools

The Grundomat Stepped Cone is a replacement front-end cone designed for Grundomat pneumatic piercing tools. This component is part of the tool’s front head assembly and helps maintain accurate boring performance by guiding the tool through the ground and supporting stable soil displacement during operation.

The stepped design helps the Grundomat stay on course while boring, especially when working through compacted soil, gravel, or ground with small fracturable obstructions. A worn or damaged stepped cone can reduce boring accuracy and affect the overall performance of the tool, so replacing it when the steps are badly worn is an important part of proper Grundomat maintenance.

This replacement stepped cone installs onto the chisel and is secured with roll pins. It is commonly replaced during front head maintenance, rebuilds, or when the original cone shows visible wear, deformation, or damaged steps.

Features:

• Replacement stepped cone for Grundomat piercing tools
• Helps maintain boring accuracy and tool direction
• Designed for the reciprocating stepped-cone head system
• Machined metal construction for heavy-duty underground use
• Installs onto the chisel and secures with roll pins
• Recommended replacement when the original cone is worn or damaged

Common signs that replacement may be needed:

• Worn or flattened cone steps
• Reduced boring accuracy
• Damaged or deformed front cone
• Excessive wear around roll pin holes
• Tool no longer holds line as expected
