Questions about this item

How deep can the 12 inch overall length actually drill in a single pass?

The 12 inch overall length allows drilling through thick workpieces or reaching deep holes in one pass, reducing the need for extensions.

What does the black oxide finish do for the high-speed steel bit?

Black oxide reduces friction and resists corrosion, helping the high-speed steel stay sharp longer during repetitive drilling.
