AUGER BIT VS SPADE BIT

AUGER BIT VS SPADE BIT

WHAT IS AN AUGER BIT?
Auger Bits feature a single-spur leading edge,
making it possible to drill clean holes in dense,
dry lumber with ease. These bits even include a
little corkscrewed tip that eliminates the
necessity to use pressure while drilling.
WHAT IS A SPADE BIT?
Spade Bits are sometimes referred to as "paddle
bits" because they appear as a paddle. Its shape
is a bit distinctive due to its squared, flat
head. This head is typically sized such that any
hole made thereupon will match the head's width

COMPARISON BETWEEN AUGER BIT SPADE BIT

• BY APPLICATION

• Auger bits generally drill cleaner holes with
  smoother sides and fewer splintering. They're
  commonly used for general wood drilling in
  construction, woodworking in gardening, and many
  other areas.
• Spade bits drill holes with rougher sides and are
  therefore utilized in areas that will be covered.

4
BY SHAPE DESIGN

• Auger bit is a spiral-shaped bit with a threaded
  tip at the front and two chisels at each tip's
  end. These chisels are liable for shaving the
  wood.
• Spade drill bits are flat. They need a
  comfortable design shaped like a spade or paddle
  with two sharp lips at each end and a pointy
  non-threaded guidance tip.

BY USE

• Auger bits require downward pressure when
  drilling, making it more comfortable. The
  threaded tip pulls the bit downwards and creates
  a self-driving mechanism, which will be in no
  time, even with just the drill's load pushing
  down.
• It is not an equivalent case for spade bits.
  Their tips could be sharp but aren't threaded,
  and thus, they don't self-drive. As a result, you
  would like to use more downward force for quick
  digging.

5
BY CUTTING ABILITY

• Due to the spiral design, auger bits are suitable
  for precision drilling. It suggests they will dig
  a hole with an equivalent width because of the
  tool when cutting straight or at an angle.
• Spade bits are suitable for customizing the form
  and size of the drilled hole. The tool can be
  easily angled at the start or as you drill, which
  allows you to make a tapered hole or a
  smaller/larger hole than the width of the flat
  blade.

BY DRILLING DEPTH

• Auger bits in drill quickly and very deep. The
  drill's depth is due to the threaded tip, which
  effortlessly self-drives the tool to very deep
  depths.
• As for spade bits, they're not recommended for
  drilling at deep depths because you'll need to
  apply tons of downward pressure. On the bright
  side, they generate less heat even at fast speeds
  in deep depths.

6
BY SHAVING REMOVAL

• Apart from drilling faster and more profound,
  auger bits evacuate shavings very efficiently. It
  is often thanks to their spiral section (flight),
  which directs shavings to the highest, leaving
  the opening clear and unclogged.
• However, with Spade Drill Bit, shavings usually
  compile above the bit within the hole, and at
  some point, you would possibly not be ready to
  see the paddle.

BY COST

• Auger bits are a bit expensive due to their
  design and shape.
• Spade bits are very affordable. Their simple flat
  design makes them cheaper than augers, and this
  is often quite logical because the fabric wont to
  build them is a smaller amount.
