Description
1. Made of high speed steel. HSS (high-speed steel) makes the drill body harder and can last a longer drilling life.
2. With the twisted design, cutting accuracy can be improved by centering the tip. It can avoid shifting the drill while working while removing dirt and particles faster and easier.
3. Suitable for processing non-ferrous metals such as copper and aluminium as well as for hard plastics. If it cannot penetrate, try to adjust the speed.
4. Please use cool and gentle, the life of the twist drill can be significantly extended by proper use.
