Century Drill 5018 1-1/8-Inch Bi-Metal Hole Saw
Century Drill 5018 supplies a 1-1/8-inch opening using a bi-metal cup with cobalt HSS teeth. Diameter and cutting depth are different measurements here: the listed 1-1/2-inch depth is not an alternative hole size or a guarantee of unrestricted reach once mounted.
Specifications and included details
- 1-1/8-inch nominal cutting diameter and listed 1-1/2-inch depth.
- 8% cobalt high-speed steel teeth on an alloy body.
- Variable-pitch tooth pattern.
- Listed materials include stainless steel, brass, aluminum and wood.
Before ordering
Compare the required opening with 1-1/8 inches, then confirm the compatible arbor and pilot for your drill. Accessories are not itemized in the supplied inventory. Use the manufacturer's cutting guidance for the specific material rather than one speed for every listed application.
Product questions and answers
Is this the same size as a one-inch cup?
No. Its nominal cutting diameter is 1-1/8 inches, one eighth larger than a one-inch cup.
Does it include an arbor and pilot?
They are not specified in the supplied inventory. Verify the compatible components needed for your setup.
Does the cobalt percentage refer to the whole cup?
No. The 8% cobalt HSS specification applies to the teeth; the body is a separate alloy component.
