Need a durable tool to drill through metal quickly and cleanly? Choose this high-speed steel (HSS) twist drill bit from RS PRO. It has a split point that can bore straight through metals like cast iron, hardened steel and even titanium without snagging or lacerating the surface of the metal.The drill bit's tip design features two sharp edges to improve grip on smooth metal surfaces and reduce the amount of pressure required to drill. This improves drilling accuracy and makes it easier to cut through tough materials, allowing you to drill longer without experiencing fatigue. The HSS material provides durability and resistance to corrosion and abrasion, so the bit won't wear out or break, even after long-term, heavy-duty use. It also has good resistance to heat, so it can withstand high friction from repeated drilling into hard materials.
