How to Use Very Small Drill Bits?

16 minutes read

When using very small drill bits, it is important to exercise caution and follow certain guidelines to ensure successful drilling and prevent the bits from breaking. Here are some general tips to use very small drill bits effectively:

  1. Choose the right material: Very small drill bits are typically made of high-speed steel (HSS) or carbide. Determine the material you want to drill and select the appropriate drill bit accordingly.
  2. Secure the workpiece: Make sure the material you are drilling is securely fixed. Use clamps or a vice to hold it in place, providing stability and preventing any unwanted movement during drilling.
  3. Mark the drilling spot: Use a pencil or marker to clearly indicate the drilling spot to ensure accuracy. Double-check the placement before proceeding.
  4. Start with a pilot hole: Due to their small size, it can be challenging for very small drill bits to begin drilling directly. Create a pilot hole using a smaller drill bit or a nail to provide a starting point for the smaller bit.
  5. Apply gentle pressure: Avoid using excessive force when drilling. Apply light and steady pressure to allow the drill bit to cut through the material gradually. Using excessive force can easily break the thin drill bits.
  6. Use lubrication: Some materials, like metal, benefit from the use of lubrication. Apply a small amount of cutting oil or lubricant to ease the drilling process and increase the bit's longevity.
  7. Drill in short intervals: If dealing with harder materials, drill in short bursts rather than continuously. This prevents the bit from overheating and reduces the risk of breakage.
  8. Clear debris: Periodically lift the drill bit from the hole to clear any accumulated debris. This helps maintain a cleaner cutting surface and reduces friction, enhancing drilling efficiency.
  9. Reduce speed: If your drill has adjustable speed settings, reduce it to a lower speed when using very small drill bits. This decreases the chances of overheating and strengthens control.
  10. Use safety precautions: Always wear protective goggles to shield your eyes from any flying debris. Additionally, consider wearing gloves to protect your hands and avoid accidents.


Remember that very small drill bits are delicate and must be handled with care. With proper technique and patience, you can effectively use these bits to perform precise drilling tasks.

How to prevent slipping or skidding while drilling with very small drill bits?

To prevent slipping or skidding while drilling with very small drill bits, you can follow these steps:

  1. Select the right drill bit: Ensure you have the appropriate drill bit size and type for the material you are drilling into. Small drill bits tend to be more delicate, so using the correct bit is crucial.
  2. Secure the workpiece: Clamp or secure the workpiece firmly to prevent it from moving during drilling. This helps to maintain stability while drilling, reducing the chances of slipping.
  3. Use a center punch: Create a small indentation with a center punch before drilling. This provides a starting point for the drill bit and helps to prevent it from slipping off the desired drilling spot.
  4. Apply light pressure: When drilling with small bits, it's important to apply gentle and even pressure. Using excessive force can cause the bit to slip or break. Apply consistent, moderate pressure to maintain control.
  5. Slow drilling speed: Set the drill to a lower speed setting when using small drill bits. High speed can make it difficult to control the drill, increasing the risk of slipping or skidding.
  6. Use a pilot hole: For more precise drilling, create a pilot hole with a smaller drill bit before using the desired size. This helps to guide the larger drill bit and reduce the chances of slipping.
  7. Lubrication: Depending on the material you are drilling into, consider using a lubricant such as cutting oil or water to reduce friction. This lubrication can prevent the bit from overheating and slipping.
  8. Maintain the drill bit: Regularly inspect and sharpen your drill bits to ensure they remain sharp and in good condition. Dull or damaged drill bits are more prone to slipping.


Remember, safety is crucial when working with power tools. Always wear appropriate safety gear, including goggles and gloves, to protect yourself from any potential accidents or injuries.


What is the thickest material that can be drilled with very small drill bits?

The thickest material that can be drilled with very small drill bits depends on various factors such as the material hardness, drill bit size, and the equipment used. However, typically, small drill bits (around 1mm or less) can successfully drill through materials like softwood, acrylic, magnesium, aluminum, brass, and even some low-carbon steels with relative ease. For thicker and harder materials, it becomes more challenging to drill with small bits, and a larger drill bit or specialized equipment may be required. Ultimately, it is important to consider the specific material properties and use appropriate techniques when drilling to ensure successful outcomes.


How to determine the best drill bit size for a specific project with very small drill bits?

When choosing the right drill bit size for a specific project, especially with very small drill bits, the following steps can be helpful:

  1. Understand the Material: Different materials require different drill bit sizes. Identify the material you're working with, such as wood, metal, plastic, or glass, as each has distinct properties that impact the selection of drill bits.
  2. Analyze the Project Requirements: Consider the task at hand, including the size and depth of the hole required. Determine if the hole needs to be a specific diameter or if it can vary within a certain range.
  3. Research Drill Bit Charts: Drill bit charts provide general guidelines for matching drill bit sizes to the desired hole size in various materials. These charts suggest appropriate bit sizes based on the hole diameter you wish to achieve.
  4. Measure and Test: If precise measurements are necessary, use a caliper or measuring tool to determine the exact diameter needed. Once you've identified the approximate size from the drill bit chart, test the bit on a scrap piece of material to ensure it meets your requirements.
  5. Consider Tolerance: Keep in mind that some projects may have tolerances that require a slightly larger or smaller hole size. Account for these allowances, especially if precision is critical.
  6. Pilot Holes: For very small drill bits, it's often helpful to start with a pilot hole. Use a slightly smaller bit to create a starter hole, which can prevent the smaller bit from drifting and increase accuracy.
  7. Consult Experts or Manufacturer Guidelines: If you have doubts or specific requirements, it's always advisable to consult experts in the field or refer to the manufacturer's guidelines for your specific project.


Remember, selecting the right drill bit size requires a combination of understanding the material, project requirements, and using available resources like drill bit charts. Additionally, practice and experimentation can help you find the best fit for your project.
