Having the right drill bit will make all the world of difference. Also make sure the bit is sharp. Most drill bits will do the work themselves with only a little bit of pressure. If you find yourself having to use a lot of force to drill, then it is probably time to throw that bit away and get another. Using dull bits can ruin your work and put unnecessary wear and tear on your drill.
Drill Bit Materials
- Steel Bits – Inexpensive and good for softwoods. Will dull quickly with hardwood and even break.
- High Speed Steel Bits – Harder than steel blades and will stay shaper slightly longer.
- Titanium Coated Bits – Cost more than High Speed Steel, but this is a tougher material and will stay sharper longer.
- Carbide Tipped – More expensive than the previous bits but will stay shaper longer than any of them.
- Cobalt Bits – Extremely hard and great for applications with heat build up because it dissipates the heat. Good for Stainless Steel and other metals.
- Use a twist bit for general drilling. A high speed bit is the best.
- When you drill concrete, brick, slate or plaster use masonry bits at low speeds.
- When drilling tile or glass use the spear point at low speeds.
- A hole saw is great to make large holes, but make sure the drill can handle the extra force or your burn the motor out very quickly.
- For metal, a step bit is best used at slow speeds.
The drill bit is what makes the cut or bore into your work. I would suggest spending a little more money and getting a better drill bit. It will last longer and cause less frustration in the long run.
