About this item

  • Size - Drilling diameter: 18mm / 23/32"; shank size: 6.5mm / 1/4"; drilling depth: 50mm / 1-31/32"; total length: 79mm / 3-3/32"; style: 2 cutters, 3 spurs; shank type: hex shank (grips the chuck or extension adapter securely and increases torque transmission.)
  • Material - Precision ground carbide tips significantly improve wear resistance and cutting performance, and provide sharp cutting edges, high strength, hardness and heat resistance. Forstner bit adopts carbon steel body, which has good strength, durability and sufficient rigidity.
  • Features - 3 spurs help guide it through wood and ensure accurate start holes, reducing slippage. Arc curve design head for easy chip-removal, more efficient perforation. Forstner drill bit enables precise, fast and clean drilling. Do not drill metal and non-ferrous metals.
  • Applications - 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.
  • Notes - Used with handheld drills, drill presses, CNC routers, and lathes. Recommended to use on desktop (fixed) equipment. Use a cutting oil or lubricant, hold still, control the speed, apply pressure gradually, and always wear protective equipment.

Have used these bits to drill maybe two hundred hiles so far for a wood turning project that I am working on. I have bored holes up to three inches deep on various type of wood from maple to wood as hard as ash. and the results have been outstanding. Not once have I had to sharpen these bits compared to others that had to sharpened often. Will by again when these wear out, but that won't be for some time to come.

The blade could be sharper. They are okay for soft wood.
