Learn how to select the right bit for your project and achieve clean, accurate drilling every time! Learn about different types, materials and where to find the best ones.

What are 2-135 Split Point Wire Size Drill Bits?

2-135 split point drill bits are specifically designed for drilling small, precise holes in various materials, including wire. The "2-135" refers to the bit's geometry and point angle. The split point design (two cutting edges) creates a self-centering action, which eliminates the need for pre-drilling and helps prevent walking or wandering during the drilling process. This makes them perfect for delicate work on wires.

Understanding the Significance of Split Point Design

The split point design is crucial for several reasons:

Self-Centering: The two cutting edges create a self-centering action, eliminating the need for pre-drilling or center punches.
Reduced Walking: It minimizes the tendency of the bit to wander off course, resulting in cleaner, more accurate holes.
Improved Penetration: The self-centering nature enhances penetration, leading to faster and easier drilling.

Common Materials and Applications

These bits are typically made from high-speed steel (HSS) or cobalt steel, ensuring durability and longevity. The choice of material often depends on the hardness of the material being drilled. Cobalt steel bits are generally tougher and better suited for harder materials.

Applications include:

Electronics Manufacturing: Creating precise holes in circuit boards, electronic components, and wire harnesses.
Jewelry Making: Drilling holes in delicate metals for beading or other adornments.
Hobby and Craft Projects: Creating precise holes in small metal parts, wire, or other materials.
Model Making: For creating detailed models where precision is critical.
Electrical Work: Drilling holes in wires and cables for connections.

Choosing the Right Size Drill Bit

The most important factor when choosing a 2-135 split point wire size drill bit is its diameter. These bits are available in a wide range of sizes, typically measured in millimeters or fractions of an inch. Consult a drill bit size chart to determine the precise diameter needed for your application. Remember to always choose a bit slightly smaller than the wire diameter to prevent splitting the wire.

Tip: Using a drill press provides much greater accuracy and control, especially when working with small wires. Hand drills can be used, but they require significantly more care and skill.

Where to Buy 2-135 Split Point Wire Size Drill Bits

These specialized bits are available from a variety of retailers, both online and offline. Some popular sources include:

Online Retailers: Amazon, eBay, and specialized tool suppliers.
Hardware Stores: Your local hardware store may stock a selection of small drill bits.
Specialty Tool Suppliers: Look for suppliers who cater specifically to electronics manufacturing, jewelry making, or other relevant industries.

Pro Tip: When buying online, read reviews to get an idea of the quality and durability of the bits.

Drill Bit Care and Maintenance

Proper care extends the life of your drill bits. Always store them in a safe, organized place to avoid damage. Clean them regularly to remove any debris that might accumulate. Avoid dropping or mishandling the bits. Lubricating the bit with cutting oil can also increase its lifespan and provide better performance.

Frequently Asked Questions (FAQs)

Q: What is the difference between a standard drill bit and a 2-135 split point bit?

A: A 2-135 split point bit has two cutting edges that meet at a 135-degree angle, creating a self-centering point. This design leads to improved accuracy and reduced walking, which is essential when drilling small, precise holes in delicate materials like wire. Standard drill bits lack this self-centering action.

Q: Can I use a 2-135 split point bit on materials other than wire?

A: Yes, these bits can be used on a variety of materials, but their primary strength lies in their ability to drill accurate, clean holes in smaller diameter materials like wire. They can also be used on plastics, wood, and softer metals.

Q: How do I prevent the wire from bending or breaking while drilling?

A: Use a low speed and light pressure when drilling. Secure the wire firmly in a vise or clamp to prevent movement. Choose the correct bit size; too large a bit can easily split the wire. Using a drill press offers better control and accuracy.

This guide provides a comprehensive overview of 2-135 split point wire size drill bits. By understanding their design, applications, and proper usage, you can ensure clean, accurate holes in your projects every time. Remember to always prioritize safety when using power tools.
