In Detail

Manufactured in our own CNC workshops, the sawtooth extension allows a 1/2" or 13mm shanked sawtooth cutter to be used for deeper boring. This is especially useful when making pepper mills and similar items. Carefully machined to be a precision fit, the extension adds a further 150mm to the length of the sawtooth cutter. Please note that these extensions cannot be used with sawtooth bits less than 23mm in diameter.

Didn't seem to run true

Had to cut down the length of the shaft to fit into morticer machine, only to find out it was out by a fraction of an inch.

Enough to make using the 80mm forester bit dangerous, as the off-centre was compounded.

Looked like a really nice bit of english engineering but check it runs true before use. And before hacking bits off!

Excellent but watch the size

I bought some metric Fisch sawtooth bits. The options for the extension are 1/2" or 13mm. The metric Fisch bits have a 12.7mm shank so you need to order the Imperial extension for these, this fits the bit shanks correctly. The metric extension would be too loose. Unfortunately the website does not quote the shank size for imperial sized Fisch sawtooth bits but you would guess they are 1/2" so also require the 12.7mm version which makes you wonder what the 13mm version fits.

I suspect the previous reviewer may have purchased the metric version as the one I bought has a 1/2" shank.

The extension is laser branded as Axminster but the bag label says Clico, either way it is very nicely made. It also includes the Allen key for securing the bit in place.

Sawtooth Shank extensio

Does the job. Needed to reduce the chuck end diameter by 2mm to fit the imperial chuck on a geared drill.
