طقم مثقاب سيلفر آند ديمينغ 9/16 5/8 11/16 3/4 13/16 7/8 15/16 1 بوصة Drill Hog

The M2 HSS tips chewed through mild steel plate like it was nothing, and the 1" bit held its edge way better than the cheap set I burned through last year. Having every size from 9/16 up to 1" in one case is handy since I'm not hunting around mid-project.

Bought this set mainly for the 3/4" and 1" bits to open up holes in plate steel for a project, and they cut way cleaner than the cheap set I had before. The M2 HSS holds an edge nicely and the shanks fit my 1/2" chuck without slipping.

Bored out a 1" hole through 3/8" plate steel with the biggest bit and it cut clean without wandering. The M2 HSS tips stayed sharp through all eight sizes, which surprised me for the price. Shank fits my half-inch chuck with no wobble at all.
