You can increase this by purchasing the forstner bit extension (sold separately). They still retain clean cutting characteristics when used drilling across the grain, but just not as clean as a true forstner bit - although acceptable for virtually all wood boring.Īll metric forstner and sawtooth bits are 90mm long with a recommended shaft installation into the chuck of 25mm, providing a maximum 65mm depth of cut.

A sawtooth design makes them able to cut more easily when drilling with the grain (such as through end-grain). Īll bits 25mm and larger purposefully have a sawtooth design. Also, these bits are ripper value if we do say so ourselves.

Simply put, you can trust an Aussie retailer to carefully test and ensure quality in design over cheap foreign knock-offs with little to no quality control, customer support or responsibility. Extension bars are available for this purpose.Especially suited for drilling deep or extra large diameter holes.The design permits large chip clearance easily.Used to true up and increase the size of an existing hole or timber imperfection.They can be used to be bore in any direction and are extremely useful for boring holes on an angle.Hence they are not deflected easily by the natural differences in hardness found in timber such as knots or strong grain patterns. Hell, when we can't find a good metric version, sometimes we just build it ourselves! What's so good about Forstners?įorstner bits are superior bits for drilling wood because they are guided by the rim and not a centre point. Sick of the woodworking industry's insistence on using imperial, when all you want is a simple, relatable metric measurement?

This is a very common use for many woodturners that make peppermills, either to sell or give away as presents. By using a Colt RotaStop Morse Taper Adaptor a woodturner no longer needs to purchase a chuck. The adaptor will take the Colt Extension Rods, which are commonly used for boring out peppermills. They give an amazingly secure fit and may need to be knocked out when no longer required. The male part is conically shaped at the back end of the chuck and fits into the female section on the power source. Have historically been used to connect a chuck to a power source on a drill press and/or a lathe. Bravo to Colt.' Christopher Schwarz, editor Popular Woodworking Magazine.

We tried to overfeed this bit, and we failed. Instead you get ribbon-like shavings, which eject easily, even from deep holes. So you don't get big disc-shaped chips, which clog the works. 'The genius in these bits is that the cutting lip is designed to bust up the chips as they are severed. RotaStop Shank System, eliminates slippage and shank damage.Works in cross grain and end grain, making it ideal for woodturners.With a Rockwell hardness of 63 they remain sharp much longer than inferior quality cutters.Much faster cutting, less heat build up due to their patent-pending cutter design.They create such smooth entry and exit holes you have to see & feel it to believe it, even on end-grain and crosscuts. These Forstners are unlike any others we've tried. We'd like to proudly introduce the COLT MaxiCut line of top quality Forstner Bits.
