Pump components often combine deep passages, stainless or cast materials and tight leakage-related tolerances, making coolant-through carbide drills a practical choice.
Coolant drills for pumps are used for oil passages, hydraulic holes, shaft holes, housing ports and stainless pump components where chip evacuation and hole quality affect assembly and leakage control. Internal coolant carbide drills help remove chips from deep passages and keep heat away from the cutting edge.

Pump parts that may need coolant drills
- Pump housings with cross holes or oil passages.
- Pump shafts and sleeves with deep axial or radial holes.
- Hydraulic and lubrication channels in stainless steel or alloy steel.
- Cast iron pump bodies where chip dust must be evacuated cleanly.
- Sealing-related holes where burrs, finish and diameter control matter.
| Pump material | Drilling challenge | Coolant drill benefit |
|---|---|---|
| Stainless steel | Heat, work hardening and long chips | Direct coolant improves edge life and chip movement. |
| Cast iron | Fine chips and abrasive wear | Coolant flow helps remove particles from deep passages. |
| Alloy steel | Depth, tolerance and tool life | Stable coolant delivery supports repeat production. |
Send your pump component drawing, material, hole depth, coolant pressure, tolerance and annual quantity. KYTOOLS can recommend standard coolant drills or custom pump drilling tools.
