16 قطعة مجموعة مثاقب سيلفر آند ديمينغ 9/16 - 1-1/2 بوصة هاي-موليبدينوم M7 DrillHog أمريكا

Bored out a 1-1/4" hole through 3/8" plate steel and the M7 cut clean without needing a pilot step. The full fractional range from 9/16 up to 1-1/2" means I finally stopped hunting for the odd sizes.

Finally replaced my mismatched jumbo bits with this full fractional run from 9/16 up to 1-1/2, and every size I actually reach for is in the index. The M7 steel holds an edge way longer than the hardware store stuff I'd been burning through on plate steel.

Bored of borrowing the shop's big bits, I grabbed this set for drilling 3/4" holes through steel plate and the M7 moly holds an edge way longer than the cheap stuff I've burned through before. All 16 sizes came oiled and sharp, no burrs on the shanks.
