How to use

Secure the step drill bit in a compatible drill chuck, align the tip with the marked drilling point and start at low speed to establish the pilot contact. Apply steady pressure and increase speed as needed while advancing through the material. Use cutting lubricant when working with metals to reduce heat and prolong bit life. After drilling, retract the bit slowly to clear chips.

Recommendations

For best results, select appropriate drill speeds and apply light, consistent pressure. Use cutting oil on ferrous metals and wear eye protection during operation.
