Baladonia Metric Forstner & Sawtooth Bits Forstner Bits

Sick of the woodworking industry's sententious insistance on using imperial, when all you want is a simple, relatable mm measurement? We've got your back here at Timbecon, which is why we stock both metric and imperial versions of every major tool and fitting.

Hell, when we can't find a good metric version, sometimes we just build it ourselves!

Forstner bits are superior bits for drilling wood because they are guided by the rim and not a centre point. Hence they are not deflected easily by the natural differences in hardness found in timber such as knots or strong grain patterns.

• They can be used to be bore in any direction and are extremely useful for boring holes on an angle.
• Used to true up and increase the size of an existing hole or timber imperfection.
• The design permits large chip clearance easily
• They have the ability to track truly
• Especially suited for drilling deep or extra large diameter holes. 
• Extension bars are available for this purpose.

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. Also, these bits are ripper value if we do say so ourselves.

All bits 25mm and larger purposefully have a sawtooth design. A sawtooth design makes them able to cut more easily when drilling with the grain (such as through end-grain). 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. 

All 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. You can increase this by purchasing the 

Sharpen by running a small flat diamond plate along the horizontal scraper cutter keeping the angle constant. The rim needs less frequent sharpening but can be touched up using a round file or diamond stone on the inside. Never grind or touch up the outside of the bit.
