Buying Guide for 3/32 135 Split Point Cobalt Fractional Bit

Understanding Cobalt Drill Bits

When I first started working with metal and harder materials, I quickly learned that having the right drill bit is essential. Cobalt drill bits are made from a high-speed steel alloy that contains about 5-8% cobalt. This composition gives them remarkable heat resistance and durability, making them perfect for drilling into tough materials like stainless steel.

Why Choose a 3/32 Size

The 3/32 inch size is often my go-to for precision tasks. This size allows me to create clean holes without causing damage to the surrounding material. Whether I’m working on a delicate project or need to create pilot holes for screws, this size has proven to be versatile. It’s perfect for applications where a smaller diameter is necessary.

Benefits of a 135 Split Point

The 135 split point design is something I appreciate every time I use it. This feature helps the bit to self-center, which minimizes walking or slipping when starting a hole. I find that it allows for quicker penetration and reduces the effort I need to put in, especially when drilling through harder materials.

Price vs. Quality

In my experience, the price of a cobalt bit can vary. While I might be tempted to go for a lower-priced option, I find that investing in a quality cobalt bit pays off in the long run. The performance and longevity often justify the higher price point, especially for serious projects.

Maintenance Tips

I’ve learned that maintaining my drill bits is key to their performance. After using my 3/32 cobalt bit, I always clean it to remove any metal shavings or debris. Storing it in a protective case also helps prevent damage. Regularly checking for wear can save me from having to replace bits too frequently.
