Main highlights

•Drilling with forstner bits to achieve a flat bottom hole or to start a deep hole turning project like on a larger vase or vessel is essentially impossible with a standard length forstner bit. To remedy this issue we have developed a heavy duty steel extension that allows you to secure a 3/8 inch shank forstner bit into the end collet.
•The forstner bit extension gives you additional 5-5/8 inches of reach to bore deeper into your projects. This will help you create larger diameter starter holes or help when you need to drill in just a little further than the standard bit length will allow. The extension can be used with forstner bits on drill presses, lathes with a drill chuck installed (drill chuck not included) or with a power drill.
•One of the most common uses for the forstner bit extension is for woodturners who need to bore out starter holes on larger vessels. However, the extension works exceptionally well for projects like salt shakers, pepper mills or even wood turned beverage mugs. Contractors use the extension when they need to bore deep holes for running cables or wires and they also use it for joining larger timbers.
•The forstner bit extender is made from solid, heavy duty machined steel. It is designed to be used with forstner bits only. The collet inside diameter is 3/8 inch. This tolerance is very tight and designed to accept forstner bits with shank sizes of 3/8 inch or slightly smaller. Please note that some forstner bit manufacturers produce bits that say 3/8 inch shank size when in fact they are not. If you measure your bit shank and it is 3/8 inch, your bit should fit once the set screws are loosened
•The collet outside diameter is 25/32 inch without the set screws protruding outward. The reason this is important is that as we mentioned earlier, some bits may have slightly different shank sizes. This means the set screws may protrude outwardly from the collet. The minimum size hole this extension will allow you to drill is 13/16 inch. Forstner bits and Machinery shown in pictures are NOT included.

Main highlights

•Size - Drilling diameter: 10mm / 13/32"; shank size: 6.35mm/ 1/4"; drilling depth: 45mm / 1-25/32"; total length: 125mm / 5"; shank type: hex shank.
•Material - The woodworking drilling tool is made of tungsten carbide, which has high strength, hardness, wear resistance, and heat resistance. The painted surface can improve rust and corrosion resistance. The heat-treated drill bit is durable, sharper, and can drill neat, smooth and burr-free holes.
•Features - The spur design ensures that the drill bit penetrates the wood accurately, effectively prevents slipping, and accurately locates the drilling hole, improving the accuracy of the operation. The three-tooth arc curve design on the head reduces cutting resistance and debris faster, thereby achieving higher work efficiency.
•Applications - Suitable for opening holes in solid wood, cork, hardwood, plywood, medium-density fiberboard, particleboard, as well as plastics, rubber, and other materials. The forstner drill bits can be applied to handheld drills, drilling machines, bench drills, vertical drills, CNC engraving machines, etc.
•Notes - Forstner bits for wood 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.
