Planet Long Series Saw Tooth Forstner Bit 4″-101.6mm
The Planet Long Series Saw Tooth Forstner Bit 4″- 101.6mm is a quick and simple way to bore out the centre of your work. Using a Forstner bit is also a great way to achieve a flat bottomed hole. You may need to do this before using a hollowing tool. With an aggressive saw tooth pattern, these are particularly suited for cutting down the grain.
Long Series Forstner Bits Features
- The long series forstner bit range have a minimum length of 150mm (6″). With cutters in a full range of sizes from 3/8″ (9.5mm) up to a massive 4″ (101.6mm). The range is designed to overlap so if you need to bore out a 4″ hole you can start smaller and work up.
- If you have a wood-turning lathe with enough power you can bore a 4″ hole in one cut. This can generate a lot of heat, so working up from small sizes when boring into green wood might be the better option.
- Planet Tools Forstner bits are possible to re-sharpen the cutting edge with a diamond hone. Wipe the hone across the flat cutting surface, this is the diagonal face that runs parallel with the shaft. Don’t sharpen the top face of the forstner bit as this will cause the cutter to fail.
- These forstner bits feature a saw tooth pattern, therefore making them suited to cutting down end grain timber.
An extension bar is also available in order to give even deeper cut – Forstner Bit Extension Bar.
