Drilling precise holes in wood is an art form unto itself. It is especially true when trying to create flat-bottomed holes. That is where spade bits<\/a> vs. Forstner bits<\/a> come in. Both excel at cutting larger holes and flat-bottomed holes in wood. The question is which to use when.<\/p>\n\n\n\n

This article will cover all the comparisons between Forstner bits<\/a> and spade bits.<\/p>\n\n\n

Spade Bit Drilling Into Wood<\/p>\n\n\n

Spade Bit<\/strong><\/h3>\n\n\n

Spade bits<\/a>, often called paddle bits, look much like a spade you would use to dig a hole. They have two verticle blades with a narrower sharp point projecting from the center. These drill bits are excellent for drilling flat-bottomed holes with a handheld drill, but they often leave rough spots.<\/p>\n\n\n\n

In addition, you can use them to drill entirely through stock, but we advise you to shoot from each side.<\/p>\n\n\n

Forstner Bit<\/strong><\/h3>\n\n\n

Invented by Benjamin Forstner<\/a> in 1874, most people use Forstner bits in conjunction with a drill press or lathe<\/a>. Occasionally though, you will see them attached to electric hand drills.<\/p>\n\n\n\n

They have a center spur that may or may not be threaded. Surrounding this center are helical flutes that shave and cut very clean holes. These blades make them ideal for creating neat and uniform flat-bottomed holes.<\/p>\n\n\n
