The Benefits of Split Point Self-Centering Drill Bits and One Thing Not to Use Them For

When it comes to drilling holes in metal, having the right tools can make all the difference. One type of drill bit that has gained popularity in recent years is the split point self-centering drill bit. But what exactly is a split point self-centering drill bit, and why should you consider using one? In this blog post, we will explore the advantages of split point self-centering drill bits over standard drill bits, and one thing you should never use them for.

What is a Split Point Self-Centering Drill Bit?

A split point self-centering drill bit is a type of drill bit that features a pointed tip with a split at the center. This design allows the bit to penetrate the material more easily and helps to prevent the bit from wandering or slipping off-center during drilling. The 135-degree split point design makes it easier and more efficient to use.

Advantages of Split Point Self-Centering Drill Bits

There are several advantages to using split point self-centering drill bits:

  1. Improved accuracy: The self-centering feature of these drill bits ensures that the hole is drilled exactly where you want it. This is especially useful when drilling holes for screws or dowel pins. No longer need to use a centering punch.
  2. Reduced wandering: The split point design helps to keep the drill bit on track, reducing the chances of it wandering or slipping off-center. This is particularly beneficial when drilling on curved or uneven surfaces. I love using them on thinner material like sheet metal.
  3. Extended bit life: Split point self-centering drill bits are typically made from high-quality materials, which makes them more durable and long-lasting compared to standard drill bits. Higher quality brands made in the USA are tapered allowing only the cutting edge to touch the service material while drilling which reduces friction. https://amzn.to/3sEORfr https://amzn.to/3SNXuz4 Friction, and the heat caused by it in my opinion is the main reason drill bits fail. I always recommend using a cutting tool oil or coolant to extend the life of your drill bits. https://amzn.to/3R2vMxa
  4. What not to do: I have been selling split point drill bits for years and the only complaint I get is chipping. The main purpose of the design of the self-centering drill bit tip is to start a hole on its own in metal without the need of a center punch. That design unfortunately weakens the cutting tip edge making the bit not a good choice for enlarging an existing hole. A reamer https://amzn.to/46fw2gE or step drill bit https://amzn.to/3R4QD2O are more suitable for doing that. I have written blogs on step bits and reamers as well.
