The Basics of Letter Size Drill Bits
Letter size drill bits are part of the jobber drill bit family. These bits have a cylindrical shank with a specific diameter and are specifically used for drilling holes in various materials. What sets letter size drill bits apart is the sizing system they employ. Instead of using metric or fractional measurements, letter size drill bits are designated by letters of the alphabet. Each letter corresponds to a specific size, allowing for accurate and consistent hole drilling.
When working with letter size drill bits, the range typically extends from letters A to Z, with A being the smallest diameter and Z being the largest. The sizes increase in increments of 0.0135 inches, providing a wide selection to accommodate different hole diameters. These drill bits are available in both high-speed steel (HSS) and cobalt materials, with the latter being more durable and suitable for drilling in tougher materials.
The versatility of letter size drill bits lies in their ability to drill holes in various materials, including wood, plastic, metal, and composites. However, the specific uses of these bits depend on their size and the material being drilled. Let’s explore some common applications of letter size drill bits.
Applications of Letter Size Drill Bits
1. Woodworking: Letter size drill bits are commonly used in woodworking projects. They are suitable for drilling pilot holes for screws, dowels, and other fasteners, as well as creating recessed holes for screw heads. The range of sizes available allows for precise hole diameters, ensuring a secure and flush fit for woodworking joints.
2. Metalworking: When it comes to metalworking, letter size drill bits are valuable tools for creating holes in metal sheets, pipes, and bars. They are widely used in industries such as automotive, aerospace, and fabrication. The high-speed steel versions are ideal for drilling in softer metals like aluminum, while cobalt drill bits are better suited for drilling in harder metals like stainless steel.
3. DIY Projects: Whether you are building furniture, installing shelves, or working on home improvement projects, letter size drill bits come in handy. From drilling holes for electrical wiring to mounting brackets, these bits offer versatility and precision. The ability to choose from a wide range of sizes ensures that you can accurately match the diameter of each hole to your specific project requirements.
4. Plastic and Composite Materials: Letter size drill bits are also effective in drilling holes in plastic and composite materials. These bits minimize the risk of cracking or splitting the material, providing a clean and precise hole. Whether you are working with PVC pipes, acrylic sheets, or fiberglass, letter size drill bits offer excellent control and results.
Tips for Using Letter Size Drill Bits
To make the most of your letter size drill bits, here are some tips to consider:
1. Use the appropriate drill speed: Different materials require different drill speeds. Consult the drill bit manufacturer’s guidelines or a drilling speed chart to ensure optimal performance and prevent damage to the drill bit or material.
2. Secure the workpiece: Before drilling, make sure your workpiece is securely clamped or held in place. This ensures stability and prevents accidents or damage during the drilling process.
3. Start with a small pilot hole: Especially when drilling into harder materials, it is advisable to start with a small pilot hole using a smaller drill bit. This helps guide the larger letter size drill bit and prevents slipping or misalignment.
4. Apply steady pressure: Maintain a consistent and steady pressure while drilling. Avoid exerting excessive force, as it can cause the bit to overheat or become stuck. Let the drill bit do the work, applying even pressure throughout the drilling process.
5. Keep the drill bit cool: When drilling into metal or other hard materials, it can generate heat that can dull the drill bit. Use cutting fluid, lubricant, or a cooling agent to keep the bit cool and prolong its lifespan.
In conclusion, letter size drill bits are versatile tools that find applications in various industries and DIY projects. Whether you need to drill precise holes in wood, metal, plastic, or composites, these bits offer the accuracy, durability, and range of sizes required for the task. By following the tips outlined above and understanding their capabilities, you can maximize the efficiency and effectiveness of these drill bits in your projects.

Frequently Asked Questions
When it comes to drill bits, letter size drill bits have their unique purposes. Here are some commonly asked questions about what letter size drill bits are used for.
1. What is the difference between letter size drill bits and other drill bits?
Letter size drill bits are a specific type of drill bits that are categorized based on letter sizes, such as A to Z. Unlike standard fractional drill bits or metric ones, letter size drill bits provide a more precise measurement for various applications. They are commonly used in applications where tight tolerances and accuracy are crucial.
For example, letter size drill bits are extensively used in metalworking industries for tasks like drilling precise holes for screws and bolts. They are also popular in woodworking for tasks like creating pilot holes for screws or doweling.
2. Can letter size drill bits be used for materials other than metal or wood?
While letter size drill bits are commonly associated with metalworking and woodworking, they can be used for other materials as well. However, it’s essential to consider the hardness and thickness of the material before using letter size drill bits.
For softer materials like plastic or certain types of composites, letter size drill bits can still be used effectively. However, for harder materials like ceramics or hardened steel, specialized drill bits designed for those materials would be more suitable to avoid dulling or damaging the bit.
3. Can letter size drill bits be used with a hand drill?
Yes, letter size drill bits can be used with a hand drill. However, it’s important to match the letter size drill bit with the appropriate chuck size of the hand drill. Additionally, using a drill press could provide better control and accuracy, especially when working with letter size drill bits on delicate or precise tasks.
When using a hand drill, it’s crucial to secure the workpiece properly and ensure a stable drilling position. It’s also recommended to start with a smaller pilot hole before drilling with the letter size drill bit to prevent wandering or slipping.
4. Are there any safety precautions to consider when using letter size drill bits?
Yes, there are several safety precautions to follow when using letter size drill bits. Always wear appropriate personal protective equipment (PPE) like safety glasses, gloves, and a dust mask, depending on the material being drilled. Also, keep long hair tied back and avoid loose-fitting clothing that could get caught in the drill.
Ensure that the drill bit is securely tightened in the chuck and check for any signs of damage or wear. Start drilling with a slow speed and increase gradually to maintain control. Avoid applying excessive force, as it may cause the drill bit to break or result in injury. Finally, always keep fingers and hands away from the drill bit and rotating parts.
5. Can letter size drill bits be resharpened?
Yes, letter size drill bits can be resharpened. However, the process requires specific sharpening tools and skills. It’s generally recommended to seek professional sharpening services or use specialized sharpening jigs designed for letter size drill bits.
If you decide to sharpen letter size drill bits yourself, ensure that you follow proper grinding techniques and maintain the original geometry of the bit. Improper sharpening can lead to a loss of precision and effectiveness. Regular maintenance and inspection of the drill bits can help identify when they need to be sharpened.
Summary
Letter size drill bits are used for drilling holes in wood, metal, and plastic materials. These bits are labeled with a letter from A to Z, with A being the smallest and Z being the largest. Each letter size corresponds to a specific diameter, making it easy to choose the right bit for the job. The smaller bits are ideal for delicate tasks, while the larger ones are used for more substantial drilling projects. It’s important to match the bit size to the screw or bolt you’re using to ensure a proper fit. Overall, letter size drill bits are versatile tools that come in handy for various DIY projects and repairs around the house.
