Forstner drill bits are designed for creating angled holes in wood. They have a sharp center point and a flat cutting edge, which allows them to cut away the wood fibers at an angle. Forstner drill bits are commonly used for creating pocket holes or for drilling into the end grain of wood.
Auger
Auger drill bits are designed for drilling deep, straight holes in wood. They have a center point and two sharp cutting edges on either side, which cut away the wood fibers as the bit is rotated. Auger drill bits are commonly used for boring out large diameter holes for electrical wiring or plumbing.
Hole Saw
Hole saws are designed for drilling large diameter holes in wood. They have a center point and a sharp cutting edge, which cuts away the wood fibers as the bit is rotated. Hole saws are commonly used for making holes for doorknobs or plumbing fixtures.
Self-Feed
Self-feed drill bits are designed for drilling large diameter holes in wood. They have a center point and a cutting edge, which cut away the wood fibers as the bit is rotated. Self-feed drill bits are commonly used for boring out large diameter holes for electrical wiring or plumbing.
When it comes to which drill bits are for wood, the choices are many, but these are the most commonly used. Brad point, spade, Forstner, auger, hole saw and self-feed drill bits are all designed to drill into wood. Each type has its own strengths and weaknesses, so it’s important to consider the type of wood you’re drilling into and the size of the hole that needs to be created before selecting the right drill bit.
