Choosing machine tool parts, coolants, and supplies can feel like comparing two different jobs: you might need a mist coolant attachment, a multi-part sprayer kit, a complete desktop CNC router, or a replacement transformer for an existing lathe. These four listings show how far the category stretches, and the right pick depends less on brand and more on what you already have on the shop floor.
Quick Take
If you only need a simple mist coolant spray for a CNC lathe or milling machine, the Mist Coolant Lubrication Spray System Unit is the smallest-ticket item here. If you already own an air compressor and want a more complete coolant mist kit, the Coolant Cooling Spray Pump Mist Sprayer System includes two sprayers plus a solenoid valve, filter, and tank. If you want a new desktop router/engraver rather than a coolant accessory, the 3018-PRO-MAX CNC router is the only complete machine in the group. And if you are maintaining a 1999 HAAS SL20 lathe, the transformer power supply is the specialized spare part.

| A specific replacement power supply for a 1999 HAAS SL20 lathe | 1999 HAAS SL20 CNC LATHE Transformer Power Supply | Used FANUC-branded part with P/N 32802, U.S. origin, and a narrow application |
Product Notes
#### Mist Coolant Lubrication Spray System Unit for CNC Lathe & Milling Machine
At USD 8.77, this is the most approachable coolant accessory in the group. It is designed with adjustable airflow and spray volume so one unit can cool, lubricate, and blow metal chips during machining. The included lines are a blue tube of roughly 30 cm and a transparent tube about 1.5 m long. That makes it a compact single-point mist spray rather than a full circulation system. The main limitation is the package: you get one spray system and two tube pieces, not multiple nozzles, a reservoir, or a solenoid valve. For a basic aftermarket mist point on a CNC lathe or milling machine, this keeps the outlay small.
#### Coolant Cooling Spray Pump Mist Sprayer System for CNC Lathe Milling Machine New
At USD 85.50, this kit moves beyond a single sprayer. The set includes two sprayers, a solenoid valve, a filter, and one tank, which makes it a more complete coolant mist arrangement for a CNC lathe or milling machine. The kit is made of high-quality material, is described as durable, and uses a compact design. The catch is air supply: a separate air compressor with 2KG-8kg air pressure must be provided before the system can be connected. If you already have the compressor, that requirement is an easy fit; if not, it adds another piece of equipment to your shop setup. This is the middle-priced coolant option and the most bundled one.
#### 3018-PRO-MAX CNC Router PVC Wood Milling Engraver Machine+Offline Controller【US
At USD 144.00, the 3018-PRO-MAX is the only product here that is a complete CNC machine instead of a coolant or replacement part. The RATTM MOTOR kit uses a GRBL 1.1F control board, an offline controller, a 775 spindle motor, and an ER11 collet. It includes a 24V power supply, a 4G USB flash drive with manual and software, plate clamps, and 10 drill bits. The working area is roughly 30 x 18 x 4.5 cm, so it is suited to smaller wood or PVC milling and engraving jobs. The practical limit is that small envelope; it is not a large-production machine, and the power supply and controller are designed for this desktop-style kit.
#### 1999 HAAS SL20 CNC LATHE 64-1420 JEC P/N 32802 TRANSFORMER POWER SUPPLY
At USD 599.99, this is the highest listed price in the group and the narrowest application. It is a used transformer power supply for a 1999 HAAS SL20 CNC lathe, identified by the 64-1420 JEC and P/N 32802 numbers in the title. The brand is FANUC and country of origin is United States. This is not a coolant supply, and it will not help a general milling machine; it is a targeted spare part for a lathe of that vintage. Choose it when your repair path points to this specific transformer power supply. The limitation is exactly that specificity: apart from the 1999 HAAS SL20 application, it lacks the broader usability of the coolant kits or the desktop router.
Final Recommendation by Use Case
- For a simple, low-cost mist coolant add-on on a lathe or milling machine, go with the Mist Coolant Lubrication Spray System Unit.
- For a compressor-fed mist setup with two sprayers, filter, tank, and solenoid valve, choose the Coolant Cooling Spray Pump Mist Sprayer System.
- For a new desktop machine that can handle wood and PVC milling or engraving, pick the 3018-PRO-MAX CNC router with offline controller.
- For a replacement transformer power supply in a 1999 HAAS SL20 lathe, the 1999 HAAS SL20 CNC LATHE transformer power supply is the specific part to match.
