2pcs 28mm Twist Drill Bits Black Nitride Coated HSS-6542 with 1/2" Reduced Shank
Specification:
Cutting Diameter: 28mm / 1.1"
Shank Diameter: 1/2"
Cutting Edge Length: 85mm / 3.35"
Overall Length: 150mm / 5.91"
Material : High Speed Steel 6542 (HSS 6542)
Finish Type: Black Nitride Coated
Shank Type: Round Shank
Tool Flute Type: Spiral
Hardened to: 65-66 HRC
Descriptions:
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. The black nitride coating increases hardness and wear resistance, allowing it to maintain its sharpness and cutting efficiency longer, and also provides corrosion resistance. 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.
Package:
2pcs x Reduced Shank Drill Bits
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.
