Benefits:

• Ni-Cr-Mo steel drill bit, reinforced and tempered
• Head created for better centering, greater speed, precision of execution
• The construction of the tip guarantees an accurate and correct guide significantly reducing the friction in the hole
• The multi-cutting edge geometry protects the tip from impact with the rods in reinforced concrete
• The discharge grooves with their considerable volume in the double helix ensure rapid chip removal
• Excellent vibration behavior
• Reduced friction and maximum energy transfer
• Centering guide and stability to torsional load
• Precise holes, noise reduction, work protection

Suitable for:

• Concrete
• Solid brick
• Natural stone
