Good To Know
Q: Do these drill bits require pilot holes? A: No, the split-point tips are designed to prevent walking and do not require pilot holes to start.
Q: Can these bits drill through thick stainless steel? A: While they handle mild steel well, drilling thick stainless steel requires low speeds and cutting fluid to avoid overheating.
