Information
6542 HSS ( also called M42 HSS) is a high-speed steel alloy with 8% or 10% cobalt, with superior red hardness than conventional high-speed steels, and less prone to chipping when used for interrupted cuts.
6542 HSS features high wear resistance, high toughness and high heat resistance, high cost performance, etc. The hardness can reach 64~66HRC after high precision quenching. The bending strength reaches 4700MPa.
Reduced Shank Drills
Reduced shank drills expand the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes.
Titanium and Nitride Coatings
Premium gold titanium and black nitride dual coatings can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular black surface.
Sharp Spiral Flutes
Sharp Spiral flutes provide neat and smooth cuts. High cutting edge strength, fast cutting speed. Spiral groove facilitates the export of metal chip, saving time and effort in operation.
Features
- High wear resistance
- High heat resistance
- High toughness
- High cost performance
- Hardened up to 64~66HRC.
- Bending strength reaches 4700MPa.
Wide Applications
- Can be used for drilling stainless steel, aluminum alloy, iron, copper, brass, metal, wood and plastic materials. Perfect tool for maintenance departments, machine shops, and other industries. Suitable for most general purpose applications.
- Suitable for hand drill, table drill processing equipment, etc.. Suitable Lubricant is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy. It can help to extend the service life of tools in tapping operations.

Would not cut properly on a lathe!

I was excited to try this one out for my use. I use 1/2" schedule 40 black pipe (6 inches) and bore them out for a .625 cold rolled steel round stock to fit inside. Easy to use the bit and was the perfect size bore.

The tip wobbles creating a larger hole.

At first, it might seem that metric vs imperial systems were to blame here, but after receiving the other sizes ordered, it would seem that the seller shipped the wrong size. Not worth the effort to exchange. Can always use an intermediate size.

Excellent forêt et très facile à percer

The bit was sharp and measured the right diameter, but it was not quite true. I have an exceptionally well aligned drill press, and this bit had a wobble at the end. I checked my drill press against 3 other high quality bits that I have to make sure it was not my drill press. It was this bit. I still used it, and it did make a slightly wider hole then it should have, but it got the job done for what I was making. I recommend you move on to a higher quality bit.

I have only drilled a few holes in plastic, it seems like it is accurate and I don't think its it's going to break as long as you don't force it though metal.

I used this bit to drill 5/8" holes in 3/16" steel plate with a drill press. I started with a 3/16" pilot hole. The new 5/8" bit did not seem to have any "bite" and only made very very small chips like a countersink bit. It finally stopped going deeper. I had to use another 1/2" bit to enlarge the pilot hole. After 2 of 4 holes were complete I had to resharpen the 5/8" bit.I would not recommend this bit to a friend

2 stars only b/c it worked but I only needed to drill thru 1/16" metal backplate to mount a toggle switch and the bit almost didn't cut it. It was a one-off project and local stores don't carry metric drill bits, so took a chance w/this one. Kudos b/c it worked but I'll purchase a whole set of good bits before I purchase another one of these.

I needed this to enlarge 1/2" holes in a vehicle frame to 13.5 mm. This bit went through the steel like butter. I really did not expect it to be as easy as it was.
