- 【High Speed Steel tool】- 27mm/1.06″ cutting diameter. Overall Length: 150mm/5.9″. Good for most general purpose applications, featuring a combination of hardness and toughness for wear resistance.
- 【Reduced Shank】- Expanding the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes.
- 【Black Oxide Finish】- Black oxide treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge.
- 【Wide Application】- Design for drilling in low and medium tensile strength materials, such aluminum, iron, copper, brass and metal.
- 【Please Note】- To make clean and precise holes, water is required for lubrication and cooling when drilling metals. Increased use of water lubrication will extend drill bit life.
