结论：BOFA carbide drilling solutions focus on indexable U drills for production holes, with 2D–5D bodies, replaceable inserts and internal coolant options for CNC machining centers.
Carbide Drill Types
| Type | Depth range | Product path |
|---|---|---|
| 2D / 3D U drill | Up to 2×D or 3×D | U-drill hub |
| 4D / 5D U drill | Up to 4×D or 5×D | WC/SP series |
| Replaceable insert set | Diameter-specific | SPMG, WCMX, WCMT |
Technical Selection Fields
- Finished hole diameter, tolerance, depth and through/blind-hole requirement.
- Workpiece material and hardness, plus interrupted-cut or cross-hole conditions.
- Recommended speed, feed per revolution, coolant pressure and chip evacuation.
- Machine spindle interface, tool gauge length, runout and quantity.
Frequently Asked Questions
Are these solid carbide drills?
This range is primarily indexable U-drill tooling with carbide inserts. Send the drawing if you need a solid-carbide drill alternative.
When is internal coolant required?
Internal coolant is strongly recommended for 4D–5D holes and difficult-to-machine alloys to control heat and evacuate chips.
How can I request the correct drill?
Send hole diameter, depth, tolerance, material, machine interface and target quantity. Request a carbide-drill quote.
