Product HighlightsDuro Dyne Drill Bits are hot rolled forged and designed for:
- Fast Cutting & Fast Starting -135º split point starts the hole where you place it. The drill does not “walk”, mar metal, or waste time.
- Long Wearing & Extra Hard - Specially hardened high speed steel makes “Super T” Drill Bits harder and longer wearing than others. This same steel/processing combination allows bits to withstand the stress of tortional twisting.
- Heavy Web Reduces Breakage -Web is the portion which is solid steel from point to shank. “Super- T” has heavier web than ordinary bits. This means more flexibility, less breakage.
