I have approximately 300 Zenith 10G x 50mm Gold Passivated Square Drive Chipboard Screws to be used to screw through the particleboard floor and joists. I will pre-drill and countersink prior.
I have a very old corded Bosch (hammer) drill but being corded it requires an extension cable. Nevertheless, it can be used for the pre-drilling and countersinking. I had zero success when used with the screws but was most likely my lack of experience and used a too high a speed setting.
But if I was to buy a new drill/driver or impact driver or both, could someone suggest a suitable quality brand and model?
I have seen this online at my local Bunnings store:
Ryobi 18V ONE+ Drill Driver 7 Impact Driver Kit
