Tax Duductions for Tools ?

Hi all. Wondering if anyone includes tools purchased to maintain a property ? Example. I needed to replace fly screens and could not find anyone that makes them in my town. I bought all the raw materlials, aluminium frame, netting etc. and made them myself. I needed a hacksaw, mitre box and a few other bits and pices.

Would these be tax deductable ?

Ta in advance.
My accountant has always deducted the cost of >$300 tools used for maintenance purposes. The only thing I get asked is to confirm the property they get allocated to. Sometimes I split the cost over multiple properties.
Anything more expensive usually goes in the low value pool.
