# Proper Feed Pressure and Speed

Proper feed pressure and drill speed are important for producing clean holes, extending tool life, and improving safety.

</div>## Feed Pressure

Feed pressure is the amount of force applied while drilling.

- Apply steady, consistent pressure
- Let the drill bit do the cutting
- Do not force the drill through the material

Too much pressure can:

- Break drill bits
- Create oversized holes
- Cause the drill to grab the material

Too little pressure can:

- Generate excessive heat
- Dull the drill bit
- Produce poor surface finish

</div>## Drill Speed

Different materials and bit sizes require different speeds.

- **Small drill bits:** Higher speeds
- **Large drill bits:** Lower speeds
- **Aluminum:** Moderate to high speeds

If the drill bit becomes extremely hot or produces poor chips, adjust the speed or feed pressure.

</div>## Signs of Proper Drilling

- Continuous metal chips are produced
- The drill cuts smoothly
- Minimal vibration occurs
- The hole is clean and round

</div>## Common Mistakes

- Pushing too hard on the drill
- Running large bits at high speed
- Using excessive force when the bit becomes dull
- Continuing to drill if the material is vibrating or moving

</div>## Key Idea

Use steady pressure and the proper drill speed for the material and bit size. Let the drill bit cut the material rather than forcing it through.
