Masonry Bit: As the name suggests, we use masonry bits to make holes on concrete, bricks, cement and stone.Hence, we can consider a wood-spur bit as a cross between twist bit and a spade bit. Unlike conventional twist bits, which have a flat end, the Wood-Spur bit has a pointed end, just like a spade bit. Wood-Spur Bit: Also known as Brad Point Bit, is a type of twist bit that is primarily used with wood.The point end centers the bit for the hole and the paddle shape part will follow to make a wider diameter. Spade Bit: This bit has a flat square shape with a point on the end to make wider holes particularly in wood.
Coming to sizes, twist bits are available from 1/16 inch to 1/2 inch. These bits come in almost all drill bits kits and you can use them to make holes in wood, metal, plastic, etc.
