AI Review Summary:
Across retailer reviews, users praise the bit’s ability to cut cleanly through stainless and thick steel while lasting longer than black oxide bits. Many highlight reduced walking and quick chip removal; several recommend using cutting oil and slower RPMs on hard metals for best results. A minority note that prolonged high-speed drilling without lubrication can dull the edge or cause heat discoloration. Quotes: “Went through 1/4-in stainless like butter,” “Holds sharpness after multiple holes,” and “Use oil—ran it hot once and it dulled.” Overall sentiment is strongly positive for durability and performance in metalwork.
