Century Drill 5021 1-5/16-Inch Cobalt Bi-Metal Hole Saw
Century Drill 5021 supplies a one-and-five-sixteenths-inch cutting diameter in a bi-metal hole-saw cup. That exact size sits one sixteenth above a 1-1/4-inch cup, making it a distinct opening choice rather than a rounded equivalent.
Specifications and included details
- 1-5/16-inch nominal cutting diameter.
- 8% cobalt high-speed steel teeth joined to an alloy body.
- Variable-pitch tooth pattern.
- Listed substrates include stainless steel, brass, aluminum, wood, plastic and fiberglass.
Before ordering
Match the exact opening and verify the required depth against the manufacturer's specification. No numeric depth or included arbor/pilot is supplied in this model's details. Check the cup connection and machine capacity before assuming an existing arbor can be reused.
Product questions and answers
Is this a 1-1/4-inch hole saw?
No. Its nominal diameter is 1-5/16 inches, one sixteenth larger than 1-1/4 inches.
Does 8% cobalt describe the entire body?
No. It is the listed HSS cutting-tooth composition. The body is a separate alloy component.
Can I assume the same cutting depth as another Century cup?
No numeric depth is supplied for this model here. Verify the model-specific depth for your workpiece.
