Drill Bit for Iron and Steel

A dependable, general-purpose twist drill bit made of high speed steel with a 118° conventional point. It is designed for a broad range of materials in the iron and steel families as well as wood, copper, and PVC. Suitable for production, maintenance, or portable drilling jobs where a single large-diameter hole is needed.

Easy Chuck Compatibility

The 1/2 in. straight shank expands the size range capacity of a standard drill chuck, allowing this large bit to be used without a specialised holder. Precision grinding maintains concentricity between shank and body for true running. No self-feeding feature is present, so steady feed pressure must be applied by the operator.

1-1/4 Inch Diameter Decides Fit

The bit diameter of 1-1/4 in. is the single specification that determines whether this tool matches the hole size required. Overall length is 6 in. with a 3 in. flute length for chip clearance. Individual piece only; buyers needing multiple sizes or a set should look elsewhere.
