Drill Hog® 8 قطع فائقة الكبر HI-Molybdenum M7 مجموعة مثاقب فضية وديمنج

Bored out a 1-3/8" hole through half-inch plate steel and it cut like butter, no chatter at all. The M7 molybdenum holds an edge way better than the cheap bits I've burned through before.

Stepped up from the 1-1/16" to the 1-1/2" bit in this set while enlarging holes on my drill press, and they cut cleanly with no chatter. The M7 molybdenum holds an edge way longer than the cheap bits I used to burn through.

Bored a 1-3/8" hole through half-inch plate steel without any chatter, and the M7 moly tip still looks new. The full fractional range from 1-1/16" up to 1-1/2" means I finally stopped hunting for the odd sizes.
