Coolant Drills for Moulds: Deep Cooling Channel Drilling Guide
July 13, 20266 phút đọcBởi Solid Carbide Direct / KYTOOLS
Mould cooling channels often need long coolant-through carbide drills because depth, straightness and chip evacuation decide whether the channel can be machined reliably.
Coolant drills for moulds are used to machine cooling channels, ejector-related holes, manifold passages and long holes in mold bases. In mould steel, the problem is usually not only hardness; it is the combination of long reach, chip evacuation, straightness and surface quality inside the channel.

Common mould drilling requirements
- Deep cooling channels in mould plates and inserts.
- Long holes that require stable straightness and controlled runout.
- Pre-hardened mould steel, tool steel or stainless mould components.
- Cross holes where burr and chip control affect downstream assembly.
- Custom overall length when catalog drills cannot reach the feature.
| Requirement | Tooling consideration | RFQ detail |
|---|---|---|
| Long cooling channel | 20D or 25D coolant drill may be needed | Send channel depth and entry condition. |
| Hard mould steel | Coating and edge preparation matter | Send material grade and hardness. |
| Custom reach | Long OAL may require special grinding | Send drawing and holder clearance. |
| Cross drilling | Chip break and burr control matter | Send through/blind/cross-hole layout. |
Send mould drawing, steel grade, hardness, cooling channel depth, diameter list and annual quantity. KYTOOLS will review standard long coolant drills or custom coolant drill options.
