Drillco1000EF Series High-Speed Steel Reduced-Shank Drill Bit, Black/Gold Oxide Finish, Round Shank with Flats, Spiral Flute, 135 Degree Split Point, 1-1/8" Size

Seems high quality - I use it for wood, not metal (needed an exact size 15/16 for a hole in wood for the Robust collet system) so I cannot comment on how it cuts metal.I was a bit disappointed to get it with rust on the shank and lower area. It was wrapped in a plastic bag sleeve, around that some brown wax paper, inside a plastic case. Not sure how it got rusty. Sprayed some ruse remover.

What can i say it drills holes. But with a bit of this size you definitely need a to use a drill press. takes a lot of pressure and be sure to sue cutting oil and a slower speed of he press.

Put it thought its paces and drill 12 hole thru 1/2" steel and it's just sharp as it was when I got it.Very happy with the Purchase of the Drillco 1000EF Series High-Speed Steel Reduced-Shank Drill Bit, Black/Gold Oxide Finish, Round Shank Bit..

I drilled through 2 inches of steel, it took awhile but it made it.

Delivered on time, sharp, and worked beautifully. Stayed sharp after more than a dozen holes in 3/4" steel.

It's a drill bit.

great price

Drilled four holes so far in one inch thick steel. Worked good so far. Thirty two holes to go and will be the real test.
