Questions about this item

Will the No 77 Twister Micro-Tuff Drill work with my existing 1/4-inch hex impact driver?

The drill has a standard shank that fits common 1/4-inch hex quick-change chucks used on most impact drivers and drill drivers.

How can I confirm the 30501800 drill is cutting correctly after installing it?

A properly running drill produces a steady, high-pitched sound and ejects fine, curled chips without excessive vibration or burning smells.

Does the 30501800 package include any lubricant or cutting fluid for the Micro-Tuff coating?

The box contains only the No 77 Twister Micro-Tuff Drill; cutting fluid or lubricant must be purchased separately for optimal performance.
