Having the right drill bit will make all the world of difference. Trying to drill a hole with the wrong bit will be enough to make any sane person go insane. Also, make sure your bit is sharp. Most drill bits will do the work themselves with only a little bit of pressure from the user. 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 as the bit is dull. Not only can dull drill ruin your work, but they put extra strain 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 sharper 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 sharper 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 drilling 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. Always use your side handle.
- 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.
