Friction reduction
Cutting oil helps lower friction when you drill metal. Less friction means drilling is easier. It also helps your drill bit last longer. Your workpiece will look better, too. Studies showthat cutting oil lowers resistance a lot. Drilling goes smoother with less force needed. Here are some research results:
| Study | Findings |
|---|---|
| Rech et al. | Lubricating oil cuts down friction during metal cutting. |
| Pin-on-ring tests | Metalworking fluid dropped the friction from 0.6 to 0.1. |
| Vegetable oil studies | Vegetable oils lower friction and help tools last longer. |
Lubrication effect
Cutting oil makes a thin, slippery layer on the metal. This layer stops the drill and metal from rubbing hard. You get less heat and less damage to your drill.
Less wear on the drill
You want your drill bits to last longer. Cutting oil helps by lowering friction and keeping drills cool. Cooling systems use cutting oil to stop overheating. If your drill stays cool, it stays sharp longer. It does not get dull fast. When drilling tough steel, cutting oil helps your drill last longer. It stops heat from building up.
Smoother drilling
Drilling feels smoother when you use cutting oil. The drill moves through metal with less pressure. You do not need as much strength. Drilling is easier and more exact. This helps when drilling fast or with lots of pressure. Use cutting oil when drilling metal. You will see the drill work much better.
Surface protection
Friction can hurt your drill and your workpiece. Cutting oil protects the metal surface. It lowers direct contact between the drill and metal.
Fewer scratches
You want your finished metal to look nice. Cutting oil helps by stopping scratches and marks. Here are ways cutting oil protects your workpiece:
- Lubrication lowers friction for better tool life and smoother finishes.
- Cooling keeps heat low, so part quality stays high.
- Cutting oil stops corrosion, so your metal stays good during and after drilling.
Using cutting oil protects your drill and your workpiece. You get longer tool life and a better final product.
Cooling and heat control
When you drill into metal, heat builds up fast. This heat can damage your drill bit and the workpiece. Cutting oil helps you control this heat, keeping your tools and materials safe.
Heat dissipation
Cutting oil acts as a coolant. It draws heat away from the drill bit and the metal. You get a safer and more stable drilling process.
Prevents overheating
If your drill bit gets too hot, it can lose its sharpness or even break. Cutting oil keeps temperatures lower. Here are some measured temperature differences:
- Maximum temperature during dry drilling at 1.3 mm depth: 110 °C
- Maximum temperature with external coolant: 60 °C
- Temperature increase with internal coolant: about 5 °C
You can see that using cutting oil or coolant makes a big difference. Lower temperatures mean your drill bit stays sharp and strong.
Maintains drill hardness
High heat can soften your drill bit. When the bit gets soft, it wears out faster and loses its cutting edge. Cutting oil helps you keep the drill bit hard by cooling it down. You get more drilling done before you need to replace your tool.
Stable performance
You want your drilling to stay steady from start to finish. Cutting oil helps you keep things under control.
Reduces risk of deformation
Heat can change the shape of your workpiece. If the metal gets too hot, it may bend or warp. Cutting oil keeps the temperature low, so your workpiece stays in the right shape. You get cleaner holes and better results.
Tip: When drilling metal use cutting oil to lubricate it. This simple step protects your drill, keeps your workpiece cool, and helps you avoid costly mistakes.
Recent studies show that using minimum quantity lubrication (MQL) gives you even better results than traditional flooded cooling. MQL improves tool life, helps chips move away from the drill, and gives you a smoother finish. You also use less cutting fluid, which saves money and helps the environment. Flooded cooling, on the other hand, leads to more tool wear and higher costs.
Cutting oil gives you control over heat and performance. You get longer tool life, better results, and a safer drilling process.
When drilling metal, use cutting oil to lubricate it
Cutting oil is not just any lubricant. You need a product made for metal drilling. Regular oils do not provide the same level of protection or cooling. When drilling metal, use cutting oil to lubricate it; you get better results and protect your tools.
