• Thick steel plate drilling
• Bridge / industrial construction work

Where it fits in your lineup

This sits at the top end of the Steel Hawg size range:

• 49-57-3000 → 3"
• 49-57-3250 → 3-1/4" (this one)

👉 Translation:

• This is bigger than the 3" cutter you saw earlier
• Still uses the same 2" deep threaded system
• It’s a maximum-capacity mag drill cutter
