Before ordering
Confirm the 11/16-inch hole size and verify chuck capacity and equipment limits for the material. Jobber length is a form designation, not a numeric length specification here. Surface treatment is not consistently specified for this exact model, so do not choose it based on an assumed coating or alloy percentage.
Product questions and answers
Is this a half-inch drill bit?
The shank is half an inch, but the cutting diameter is 11/16 inch. Match the opening size to the cutting diameter.
Does SP identify a multi-size conical step drill?
Here it identifies step-point geometry on a fixed-diameter twist drill. It does not provide a range of selectable hole diameters.
Is a Nitro-Carbonized treatment confirmed for this exact bit?
The supplied model-specific specifications identify hi-molybdenum tool steel but do not establish an exact treatment. Verify that detail before making it a requirement.
