طقم مثاقيب سوبر بريميوم سيلفر آند ديمينغ 8 قطع 9/16" إلى 1" M7

Finally drilled clean 1" holes through steel plate without the bit wandering or smoking. The M7 molybdenum holds an edge way better than the basic sets I've used, and having every fractional size from 9/16" up in one case is handy.

I've been burning through cheap bits on my drill press until I got this M7 molybdenum set. The 5/8" and 3/4" sizes cut clean holes in mild steel without wandering, and the silver and deming shanks actually fit my chuck properly.

The 1" bit chewed through a steel plate on my drill press without any chatter, and the M7 molybdenum held its edge way better than the hardware store junk I had before. Having every size from 9/16 to 1" in one set means I'm not hunting around mid-project.
