With two cutting edges

• CBN (cubical boron nitride), deep ground
• Stepless drilling and widening of holes within the diameter range of 3–61 mm
• No countersinking or pre-drilling required
• Burr-free drilling without causing the sheet metal to deform. Excellent heat conductivity for longer service life thanks to axial and radial CBN relief grinding
• Mounting shank with three-phase grinding
• With laser scale for easy identification of the required drilling hole diameter

Notice

• Speed table included
• Increase service life and cutting power using drilling and cutting oil or cutting paste

• For universal use
• Also suitable for drilling very thin sheets
