This twist drill bit from RS PRO will allow you to drill quickly and cleanly through extremely hard metals. It's made from high-speed steel (HSS), so it's tough enough to cut through concrete, cast iron and even titanium.
This drill bit has a split point that can bore through hard surfaces without lacerating the material or leaving snags. The two sharp edges grip onto smooth metals for more accurate drilling and reduce the amount of pressure you need to apply. The spiral fluting also helps channel debris away from the drilling path for a cleaner cut. The HSS material is highly durable and resistant to corrosion, so it will last a long time without the need for frequent sharpening. It also provides excellent thermal resistance, so the drill bit won't wear out or break due to friction. This product meets DIN 338 standards for high-performance, high-quality drill bits.
