Asked by: dardee
Thank you for your question. The HCFC2244 drill bit is use for concrete drilling only. You would need a titanium or a cobalt drill bit for steel, however, the largest diameter we offer is 1/2". For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from M-F 7a-7p CST.
