Hole Saw for Steel
The Greenlee 825 is a bi-metal hole saw designed for cutting steel. Its variable 4/6 tooth pitch reduces vibration and extends blade life when drilling through ferrous materials. It suits electricians and maintenance technicians who need clean holes in junction boxes or enclosures.
Arbor Not Included
This saw ships without an arbor, so you must supply a compatible shank that accepts the 5/16, 3/8 or 1/2 inch sizes listed. Forgetting to order the correct arbor is the most common delay, and the pilot drill must be 1/4 inch diameter by 4-1/4 inch length to match the saw depth.
1-3/8 Inch Diameter
The saw cuts a maximum depth of 1-5/8 inch, which handles standard electrical box thicknesses and sheet metal panels. It is not impact rated, so avoid using it with hammer or impact drivers where shock loads can strip teeth or crack the bi-metal weld.
Highlights
- Variable pitch teeth cut steel smoothly
- Bi-metal tooth material resists wear
- 1-5/8 in maximum cutting depth
