Cheap generic drill bits aren't always the sharpest deals that will make the cut with many people, but I think some of the sets on offer are decent enough compared to having to buy it elsewhere later if you only need them "just incase" or for the once-off job.
In particular these seem to be well priced compared to elsewhere particularly with Bunnings not dropping their prices:
* Forstner set - $27.90 @ Bunnings (https://www.bunnings.com.au/ultra-forstner-bit-set-5-pack_p6… the ratings don't sound promising to be worth paying extra), and >$13 on eBay
* Step/cone drill set - $29.98 @ Bunnings (https://www.bunnings.com.au/craftright-3-piece-step-drill-se…)
These "Assorted Specialist Drill Sets" were in catalogue for Sat 24 Oct but due to the delays were only available in VIC from yesterday.
Also now available at Albury and Lavington NSW. We’ve been suffering with your Vic (sales) restrictions too….
