Feature(may vary by option.)

●High Speed Steel tool - 15mm cutting diameter. 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

Information

6542 HSS ( also called M42 HSS) is a high-speed steel alloy with 8% or 10% cobalt, with superior red hardness than conventional high-speed steels, and less prone to chipping when used for interrupted cuts.

6542 HSS features high wear resistance, high toughness and high heat resistance, high cost performance, etc. The hardness can reach 64~66HRC after high precision quenching. The bending strength reaches 4700MPa.

Reduced Shank Drills

Reduced shank drills expand the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes.

Black Oxide and Nitride Coatings

Black oxide and nitrogen treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge.

Sharp Spiral Flutes

Sharp Spiral flutes provide neat and smooth cuts. High cutting edge strength, fast cutting speed. Spiral groove facilitates the export of metal chip, saving time and effort in operation.

Features

  • High wear resistance
  • High toughness
  • High heat resistance
  • High cost performance
  • Hardened up to 64~66HRC.
  • Bending strength reaches 4700MPa

Wide Applications

  • Design for drilling in low and medium tensile strength materials, such aluminum, iron, copper, brass and metal, wood and plastic materials. Suitable for most general purpose applications.
  • Suitable for hand drill, table drill processing equipment, etc.. Suitable Lubricant is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy. It can help to extend the service life of tools in tapping operations.
