Drill America - DWDRSD7/8 7/8" Reduced Shank High Speed Steel Drill Bit with 1/2" Shank, DWDRSD Series

Great drill. Low cost and delivery to my door on an uncommon drill size

Needed an odd size 55/64” bit to do drag link flip kit on my jeep. This cheapo $12 bit was more than half the price I could find anywhere else, and it cut through the solid metal steering knuckle like butter and tracked perfectly using only a 12volt battery drill. Very surprised by its performance would highly recommend.

Good quality.. drilled 5/8 plate used a good cutting oil and was impressed

This bit was good for 6 holes through 1/4" mild steel before getting too dull, and that was with lubrication and pre-drilling a pilot hole. If you only need it for one project it's a good option considering the low price, but it is a disposable item. If you need to drill many holes through steel get a cobalt bit.

I purchased this bit in order to ream out a smaller hole (5/8) to a larger one (15/16) to adapt a 3-point implement from cat-0 to cat-1. As soon as the bit hit the implement I knew it wasn't going to work. It didn't cut, it bounced off. I kept going, pushing harder, hoping maybe it'd create enough of an edge and start cutting. It never did cut even though I did manage to get a few metal chips off. In retrospect I think some of the chips that were coming off were actually the drill bit itself. You can see from the photo that the cutting edge on the bit rounded off nicely and quickly from the implement's steel. In the bit's defense, the steel I'm drilling into is old, likely from the 1950s or 1960s so YMMV in newer, softer steel.

Quick delivery & work perfectly!

They improved the ride

Not a handy person, I approached the need to drill into a bedroom wall only bit by bit over a week. I thought I'd end up having bit off more than I could chew. I already had a bit-ter experience buying a drill bit at a local hardware store: the young person hesitated not a bit as she sold me a bit for a larger drill. And I didn't know enough about drill sizes, not even a bit, to ask. I was so unhappy that I bit the inside of my cheek. Fortunately, the Drill America product quelled my bit-termess. It stood firm, plunging itself into the wall, whirling like mad as my 30-year old Sears drill spun it around. The wall was not a bit resistant. A better bit can't be bought.
