Description
1. High-speed steel tool is good for most general purpose applications, featuring a combination of hardness and toughness for wear resistance
2. Reduced shank drill expand the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes.
3. Polished treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge.
4. This Reduced Shank Drill Bit is made of ordinary high-speed steel, only applicable to aluminum, copper, cork, plaster, plastic, rubber and other ordinary soft material drilling (do not exceed the scope of use).
5. Running in a counterclockwise direction (right-hand cut), spiral fluted tool evacuates chips up and out of the cut to reduce clogging.
Use Note
1. To make clean and precise holes, water is required for lubrication and cooling when drilling metals.
2. Low drill pressure and increased use of water lubrication will extend drill bit life.

All I have to drill with this is plastic (PLA) I have to deburr the edge to get a clean cut. I got a cheap bit for a reason but this is ridiculous.

garbage! I would not even trust this to drill wood! The metal I was to drill had more strength than the drill bit. Do not buy!!!

Price was good quality was good for the price. I needed to drill a 23 mm hole in mild steel to fit some bushings. This product was priced right for the small job i had to do. Hole size was accurate. delivery was quick. Would buy from Utoolmart again

The drill was undersize, lands were ground crooked. Surface finish was rough. The drill point was incorrectly ground with no clearance to the cutting lips. I kept it because it's only being used to clean out holes in plastic. I would not trust this for any type of metal.
