Description:This drill bit would bore precise, flat-bottomed holes in wood, in any orientation with respect to the wood grain. They can cut on the edge of a block of wood, and can cut overlapping holes. Because of the flat bottom to the hole, they are useful for drilling through veneer already glued to add an inlay. They require great force to push them into the material, so are normally used in drill presses or lathes.Features:Made from hard cemented carbide, this wood drill bit will perform quite well in woodworking hole drilling.The bit includes a center point which guides it throughout the cut and incidentally spoils the otherwise flat bottom of the hole.The cylindrical cutter around the perimeter shears the wood fibers at the edge of the bore, and also helps guide the bit into the material more precisely.This hole boring bit has radial cutting edges to plane off the material at the bottom of the hole.There are 11 different sizes of drill bit from which you can choose the one you need to use.Specifications:Material: Cemented carbideColor: As pictures showCutting Diameter: 10mm, 14mm, 19mm, 28mm, 32mm, 35mm, 38mm, 42mm, 45mm, 55mm, 65mm(Optional)Boring Depth: 120mm / 4.72"Quantity: 1Package Includes:1 x Drill Bit
