Stewart Fastener USHD1/4 Drill Bit 1/4 Inch 135 Split Point 12pk

Product Description

The STEWART FASTENER USHD1/4 is a 1/4-inch twist drill bit featuring a 135-degree split point tip geometry. The split point design eliminates the need for a center punch by preventing the bit from walking on contact with the work surface, allowing for immediate, accurate entry. This bit is suited for use in metal fabrication, HVAC sheet metal work, electrical rough-in, and general mechanical installation tasks where consistent hole placement and clean entry are required. It is sold in a pack of 12, making it a practical bench stock item for trade use.

This drill bit is appropriate for residential and commercial jobsite applications where 1/4-inch diameter holes are required in steel, aluminum, or similar materials. Common scenarios include drilling pilot holes for fasteners, conduit knockout work, sheet metal penetrations, and structural attachment points. The 12-piece quantity supports crew use and reduces downtime from bit wear during production work.
