Custom coolant drills solve drilling problems that catalog tools cannot handle, including special length, step geometry, coolant holes, coatings and tight tolerances.
Custom coolant drills are drawing-based carbide drills with internal coolant channels. Buyers usually need them when the hole is too deep, the diameter is non-standard, the tool needs multiple steps, the bottom shape is special or the work material causes chip packing and heat problems.
Custom coolant drill sourcing
Common custom coolant drill types
- Long coolant drills for 15D, 20D, 25D or special overall length.
- Step coolant drills for multi-diameter holes in one operation.
- Flat-bottom coolant drills for blind holes and counterbore features.
- Micro coolant drills for small-diameter titanium or stainless applications.
- Double-margin coolant drills for guidance and hole stability.
- Private-label coolant drills for distributors and tool brands.
