• CBN (cubical boron nitride) deep ground<br />
• Universally suitable. Stepless drilling and widening of holes within the diameter range 3-61 mm<br />
• Suitable for drilling of very thin sheet metal<br />
• No countersinking or pre-drilling<br />
• Speed table enclosed<br />
• Burr-free drilling without deforming the sheet metal<br />
• Excellent heat conductivity for improved tool life due to radial and axial relief grinding<br />
• Shank 3 phase ground<br />
• With laser scale, therefore easy indication of required drill hole diameter<br />
