Milling shoes can be divided into three kinds: flat-bottom (or concave-bottom) milling shoes, guide mill shoes, and come mill shoes according to their structure and shape At the milling surface, the carbide particles are built up by welding, which plays a part of self-milling. It is used to mill the fallen substances, such as bolts, nuts, tooth wheels, slip dogs, fittings for the deep-well pumps, etc.
Milling shoes are essential tools used in wellbore operations to remove obstructions, cut casing windows, and repair casing sections. They are designed for milling down metallic objects, including bolts, nuts, slip dogs, and components of deep-well pumps. Constructed with high-quality carbide materials, these shoes provide efficient cutting, grinding, and debris removal during drilling and workover operations.

Milling shoes are specialized tools used in drilling operations to grind and remove obstructions in the wellbore. These tools are divided into three types based on their structure and application:
Flat-bottom milling shoes – Designed for general milling operations and removing debris.
Concave-bottom milling shoes – Used for efficient milling and better contact with the target material.
Guide mill shoes – Suitable for window cutting and repairs in casing wells.
The milling surface is reinforced with carbide particles through welding, enabling self-milling capabilities. This enhances durability and performance in demanding drilling environments. These tools effectively mill down various fallen substances, making them crucial in deep-well applications.
