Ratings & Reviews for Spyder Stinger Mach-Blue 10 -Piece 1/4-in High-speed Steel Jobber Length Twist Drill Bit Set

Cool looking fast bits.

Very nice bits, look good and fit into an impact driver. Seem to work very well for what ive used them for.

ok for thin soft metal and softer metal

I tried using them to drill some 1/4 mild carbon steel and each bit I used running slow and with oil dulled about an 1/8 in to the plate. maybe I got a bad batch idk. Good for thin metal, plastic and wood tho.

Buy this set!

It did the job I needed it to do

Brittle

These break extremely easily. Had them less than 1 week and almost all of them are broken.

Worked when cobalt wouldn’t.

These worked on hard metal when other bits I had didn’t. I had a screw stud on my motorcycle forks break off inside when I was backing them off to put a new part on. The most important part of my bike ( holds the front drive bar on….i needed something to drill out the stud so I could tap a new set of threads in. These bits made quick work of what my expensive cobalt bits couldn’t do the day before. Highly recommend. No price is too much for my safety…..

Not a good product

It was supposed to drill into metal but it broke.

Great quick change bits.

Cut right through metal that my other, just sharpened bits could not get through.

Not what they said

I bought these bits to drill though a broken exhaust bolt. They did not do the job at all would not recommend for hardened steel or exhaust bolts. Didn’t even stay sharp they became dull quick might be good for soft metal and wood but no hardened steel

Great but one bit not straight

The drill bits are great for steel, but one bit in my set was not straight and I will be returning the set for a replacement.

long lasting

works great

Good Stuff Here!

Loved this... I needed to drill out a broken lugnut hub stem on my Honda Accord, this thing went through the metal better than anything else I tried.

Broken Bit!

I hte the product! The bit broke the first time i used it!

NO WARRANTY!

One of the bits broke at the shank when it got bound up drilling aluminum. As I expected, the soft aluminum shank failed and although I can use the bit in a regular chick drill, it no longer fits in my quick release chuck. I expected this to be the failure point and I wasn't wrong. The bits themselves are sharp and durable but the shanks for everything 1/4" and smaller are swaged aluminum and that is not "impact rated". I wouldn't be angry but the customer service rep says there is no warran...
