Wood boring bit which is used with a power drill to shave wood in a circular section equal in diameter to the width of the head of the bit. The flat head, whose edges are ground to a beveled edge, has a point used to center the bit in the wood. The turning shank forces the point into the wood. |
| Spade bits
|
|
Spade bits (sometimes called power wood bits or flat boring bits) are inexpensive, disposable wood-drilling bits which scrape instead of cut. They quickly bore holes up to 2 inches in wood and composition wood products where they are efficient, but rough, hole-forming is acceptable. They have slim shanks, flat paddle blades and long sharp points. The width of the paddle equals the diameter of the hole. Spade bits perform best at higher speeds. |
