Make sure there are no nails or other metal objects in the wood before drilling. The sprayed coating has a smooth, even surface that resists rust and corrosion. K30/C1/YG8 grade tungsten carbide tips have excellent hardness, wear resistance, heat resistance, ensuring long-lasting performance and extended tool life. Provides precision drilling for smoother and more efficient cutting. The spur help guide it through wood and ensure accurate start holes, reducing slippage. Arc curve design head for easy chip-removal, more efficient perforation. The industrial grade forstner bit is suitable for softwood, hardwood, solid wood, plywood, coated particle board, laminate and MDF. Easily drills flat-bottomed and pocket holes with precise, smooth finish. Widely used for furniture joints and woodworking projects, such as mortise joints, dowels, hinge cups, shelf pin, pocket screw. Used with handheld drills, drill presses, CNC routers, and lathes. The forstner drill bit adopts 45# carbon steel shank, which has good strength, durability and sufficient rigidity. Recommended to use on desktop (fixed) equipment. Note: Use a cutting oil or lubricant, control the speed, apply pressure gradually, and always wear personal protective equipment. Always keep the forstner bit firmly in place when drilling. The cutting edge and tip should be sharpened in time.
