Set of 8 Concrete and Granite Drill Bits DIAGER Ø 3 to 10 mm - Series 207B

Premium Finish

This concrete drill bit features a 1/2 Gold finish that ensures optimal drilling quality and increased wear resistance. The treated surface allows efficient penetration into hard materials while reducing mechanical effort.

Water-Free Lubrication

Designed to operate without water as a lubricant, this drill bit significantly simplifies drilling operations on construction sites. The absence of cooling liquid eliminates logistical constraints while maintaining consistent cutting performance.

Optimized Geometry

The positive sharpening incorporates a precise centering tip that ensures stable starting and straight drilling from first contact. The L-shaped helix geometry optimizes debris evacuation and reduces friction for smooth progression through reinforced concrete.
