The tools / Drills

There has always been a need for drilling holes in wood;  for joinery, pegging, sewing with roots, in log building and more.The first drills were sharp stones turned back and forth while pressed against the wood. Next step was to use wooden handles that could be twisted between the palms, followed by various devices to heighten rotation speeds.A drill consists of a handle and a drill bit. There are many types of handles and drills.

Drill handles:

  • A brace gives great control and strength. It is normally used for holes sized 10 mm and larger, and works best if you use auger bits.
  • The hand drill is smaller and easier to use, intended for drills up to 10 mm. You can use common drill bits or bits with brad points.
     

Drills:

  • Augers are drills with t-handles and a lead screw pulling the drill into the wood. There are augers both for end grain and for cross grain work. They are excellent for drilling large holes, 15 – 30 mm.
  • HSS drill are made for drilling in metal but works equally well in wood, best for holes 3 – 8 mm.
  • Drills with brad point, only for woodwork. Mostly used for holes 3 – 10 mm.Just like augers auger bits have lead screws pulling the drill into the wood. It has flukes and cutting lips cutting the fibers and lifting the shavings. A working auger bit takes the shavings out of the hole with no need to lift the drill. They are used for holes 10 mm and more.
  • Flat bits are always used in electric drills, mostly for holes 6 – 38 mm.
