Uxcell Forstner Drill Bit 20mm (25/32") Dia 90mm (3-17/32") Long YG8/C1 Tungsten Carbide Wood Forstner Bits

1. The forstner bit is made of tungsten carbide, which has high strength, hardness, wear resistance, and heat resistance. The painted surface can improve rust and corrosion resistance.
2. The design of the spur helps guide the drill bits through the wood accurately, prevents slipping, and ensures the accurate position of the starting hole. The arc curve design of the head has less resistance, which can remove debris faster and make your work more efficient.
3. The heat-treated drill bit can be repeatedly sharpened for a longer service life, and can achieve neat, smooth, burr-free holes.
4. Metric forstner bit sets are suitable for opening holes in solid wood, cork, hardwood, plywood, medium-density fiberboard, particleboard, as well as plastics, rubber and other materials. The standard shank diameter can be applied to handheld drills, drilling machines, bench drills, vertical drills, CNC engraving machines.
5. It cannot be used for metal processing. The material must be fixed when cutting, and the drill bit should be perpendicular to the material. When processing hardwood, water, oil or lubricant can be used to improve drilling accuracy and quality.
