Coolant Line specs
Setup notes and briefing numbers for Coolant Line.
Coolant line fit and reach
The Coolant Line specification covers the configuration, connection details, and the practical limits to check before fitting. Match the line to your machine layout and cutting conditions.
Check the hose diameter, nozzle style, and mounting thread before you order or fit the line. On spindle setups cutting aluminium, the stream must reach the tool tip without spraying the guard, cable chain, or vacuum shoe. Shops in Gauteng often run dry on wood and mist on non-ferrous work, so the line spec needs to match that changeover.
Measure the available clearance around the spindle body and Z travel, especially on compact routers with dust extraction close to the collet. A quick photo of the bracket area helps confirm whether the line can bend cleanly without kinking at full stroke. Keep the machine pressure reading with the setup notes so the next operator does not guess.
Included details on this sheet
Check the connection type, segment length, nozzle opening, and the usual pressure range on the machine. It also helps tie the line to the correct holder, bracket, or manifold point when more than one coolant feed sits on the same head. Use the naming exactly as listed so purchasing and setup refer to the same part.
Match Coolant Line specs with the spindle position, pump output, and the fluid you actually run in the tank. Before fitting, compare the thread, hose route, and swing radius against nearby guards and covers. Bit orders depend on the shank size, the material and the router you run them on.
- Nozzle aimed at cutter tip
- Bracket clearance checked at full Z
- Pump pressure noted from machine gauge
Workshop conditions affecting coolant lines
Coastal shops need to watch corrosion on fittings, clips, and exposed metal near the coolant circuit. Inland dust around routers can settle on open nozzles and reduce flow, especially where MDF cutting shares space with aluminium work. Older machines may also have mixed thread standards, so confirm the port instead of assuming a direct fit.
During load-shedding recovery, prime the pump and check flow before restarting a job that depends on coolant at the cut. Warm afternoons in closed factories can thin some fluids and change spray pattern at the nozzle. A short test run against scrap will show whether the stream stays on the edge and clears chips properly.

Checks before final setup
Record the machine model, spindle area photos, and any leaks, poor aim, or chip build-up seen with the current line. Note whether the job is flood, drip, or mist so the spec matches the duty.
Keep the pressure value, nozzle position, and fluid type with the job card after the first successful cut. That record helps when the same machine swaps from board cutting to aluminium parts and the coolant setting needs to be repeated accurately.
