RS PRO HSS Twist Drill Bit, 0.4 mm x 21 mm


Choose this twist drill bit from RS PRO when you need to drill through metal quickly and cleanly. It has a split point, so it can bore straight through the toughest materials without leaving snags or lacerations.
This durable product is made from high-speed steel (HSS), so it's strong enough to cut through stone, cast iron and even titanium. The material is also highly resistant to corrosion and heat, so it won't blunt or wear out from friction or excessive use. The drill bit's grooved tip improves the grip on smooth metal surfaces. This increases the accuracy of your drilling and reduces the amount of pressure required, so you can drill for longer periods of time without fatigue. The spiral flutes quickly channel debris away from the bore hole, making a cleaner cut.
