Uxcell 17mm Dia 1/2" Straight Shank HSS 9341 Reduced Shank Drill Bits Black Oxide

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. Black oxide treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge.
4. Design for drilling in low and medium tensile strength materials, such aluminum, iron, copper, brass and metal.
5. Running in a counterclockwise direction (right-hand cut), spiral fluted tool evacuates chips up and out of the cut to reduce clogging.

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.
