HARFINGTON Forstner Drill Bit 20mm (25/32") Dia 125mm (5") Extra Long Tungsten Carbide Forstner Bit Opener for Hinge Wood Hole Drilling Woodworking

Size - Drilling diameter: 20mm / 25/32"; shank size: 8mm / 5/16"; drilling depth (max.): 90mm / 3-9/16"; total length: 125mm / 5"; shank type: hex shank; design: 2 cutters, 3 spurs Material - Heat-treated tungsten carbide tips provide excellent hardness and toughness, wear resistance, heat resistance for long-lasting performance and extended tool life. The sprayed coating has a smooth, even surface that resists rust and corrosion. Features - The spur help guide it through wood and ensure accurate start holes, reducing slippage. The head adopts arc curve design head for easy chip-removal, more efficient perforation. Drill precise, smooth, and neat holes without burrs. Applications - Forstner bit is suitable for softwood, hardwood, solid wood, plywood, 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. Note - Used with handheld drills, drill presses, CNC routers etc.. Recommended to use on desktop (fixed) equipment. Always keep the forstner bit firmly in place when drilling. Do not drill metal and non-ferrous metals. Use a cutting oil or lubricant, hold still, control the speed, apply pressure gradually, and always wear protective equipment. Heat-treated tungsten carbide tips provide excellent hardness and toughness, wear resistance and heat resistance for long-lasting performance and extended tool life. The sprayed coating has a smooth, even surface that resists rust and corrosion. Adopts 45# carbon steel shank, which has good strength, durability and sufficient rigidity.
The spur help guide it through wood and ensure accurate start holes, reducing slippage. The head adopts arc curve design for easy chip-removal, more efficient perforation. It can drill precise, smooth, and neat holes without burrs.
The 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. Hex shank grips the chuck or extension adapter securely and increases torque transmission, reducing slippage inside the chuck. Recommended to use on desktop (fixed) equipment. Always keep the forstner bit firmly in place when drilling.
Note: Do not drill metal and non-ferrous metals. Make sure there are no nails or other metal objects in the wood before drilling. Use a cutting oil or lubricant, control the speed, apply pressure gradually, and always wear personal protective equipment. The cutting edge and tip should be sharpened in time.
