Century Drill 5074 5-Inch Cobalt Bi-Metal Hole Saw
Century Drill 5074 provides a five-inch opening size in a bi-metal hole-saw cup. At this larger diameter, confirming the drill and arbor capacity matters alongside the material and stock thickness; the nominal opening does not imply compatibility with every portable drill.
Specifications and included details
- 5-inch nominal cutting diameter; listed 1-1/2-inch cutting depth.
- 8% cobalt high-speed steel teeth joined to an alloy body.
- Variable-pitch tooth pattern.
- Listed applications include stainless steel, brass, aluminum, wood and fiberglass.
Before ordering
Verify the intended five-inch opening, stock thickness and manufacturer's machine-capacity requirements. Match a compatible arbor and pilot to the cup; neither is itemized as included. Select cutting conditions for the actual substrate, and do not treat product shipping dimensions as the hole diameter.
Product questions and answers
Can the five-inch diameter be treated as cutting depth?
No. Five inches is the nominal hole diameter; the listed cutting depth is 1-1/2 inches.
Will any drill that holds an arbor handle this cup?
Connection fit alone is insufficient. Confirm the drill's supported hole-saw size and material-specific capacity.
Are the teeth and body the same material?
No. The teeth are listed as 8% cobalt HSS and are joined to a separate alloy body in bi-metal construction.
