M2 STEP DRILL BIT SET, 3 PIECE METAL SET - METRIC (4MM - 32MM)

- Used to drill a range of different sized holes with a single bit
- Since each bit size drill holes less than 1/4″ deep, a step bit is mainly used for drilling thin     material such as sheet metal
- Each step in the drill enlarges the original hole. The smallest bits are self-starting in that      they need no pilot drill to start off the hole
- Sheet metal work is associated with step drill bits
- Made from M2 High Speed Steel (HSS) offering the best combination of strength, heat         and wear resistance
- Fully ground M2 HSS material increases drill life
- 135° Split point cuts faster and reduces wandering
- Precision engineered shank for accurate hole size
- Quick and efficient swarf clearance allows clog-free precision drilling
