【Four Times Sharper】Our stepped drill bits feature a stepped design for increased sharpness, making them four times sharper than traditional drill bits. Drill faster, increase lifespan, and reduce heat compared.
【Stronger and Reliable】Precision ground from heat-treated quality M2 High Speed Steel and blue Onyx oxide coated to prevent chip build-up.
