"Swarts has always been a great product as far as I'm concerned and this one is no exception. The bits are super sharp and as durable as any I have had so far. Love this purchase!"

"These work well. In wood, aluminium and plastic you can run these at high speed. But on steel you need to use a very low speed. The steel should peel up in short strips. Otherwise the leading edge will heat and then blunt."

"Good quality drill bits, handy for any occasion. Cobalt can be brittle, but with care it did the job nicely for me and I used a drilling and cutting oil."

"These drill bits are tough and the case is nice. I highly recommend these. I use them almost every weekend on metal projects and they barely even look worn."
"drill bits are good and sharp, and they are good quality as well! They have already saved my butt a couple of times, ultimately making for a good day when leaving the shop!"
"This is a very nice cobalt drill bits. Even though these are "High-speed" drill bits, that doesn't mean you go full throttle when drilling holes. Take your time, slow down the RPMs, use a little bit of cutting oil and these babies will cut through anything and you'll still have a nice, sharp bit when you're done. Very impressed with this bit and I would buy again."
Your service and in particular, the delivery was up there with the fastest I have experienced. Bought at same time as other items.
Brilliant drill bits for harder steel, in my case it’s stainless steel. Excellent product at reasonable price and quick delivery.
The Gold Bit was a little hard to drill low Gauge steel BUT the Cobalt Drill Bit made light work of drilling this low gauge steel
Did not drill high tensile steel.... Had to sharpen a tungsten tip drill to do the job.
