How do you use it as a drill?

By using the DW0521 Keyless Chuck, you can transform this impact driver into a drill.

How long can I expect the battery to last on a single charge for HVAC service work? Just starting out

It lasts quite a while. If you are driving screws for sheet metal, will not last long, but you should get at least 2 hours of steady use.

What is the accesory required to use the DCF809 drill driver?

Thank you for your question! If you meant what other items do you need to operate this drill, you will need to purchase a battery and charger separately. Both are sold at our storefront SunshineSeller789. The most commonly purchased battery for this drill is the DCB201 and the charger is the DCB107. We do have chargers that work faster and batteries with higher Ah capacities if you prefer to upgrade. If you meant what type of bits does it take, it is a "Drop and load chuck which accepts 1 in. tips". Hope that information helps you! Great question!

Excellent little tool. I was driving six inch screws, with T40 torx heads into a treated lumber, and it did a fantastic job. No issues whatsoever, very happy!
