Thermally improved drill bits designed for drilling holes in high-density materials. Due to the use of a carbide tip at the tip, the cutting properties are maintained for a long time.

- made of special steel with AISI (American Iron Steel Institute) specification - A322 / G5140 resistant to bending, abrasion and twisting
- manganese in the composition increases impact strength and hardness
- chrome provides greater resistance to abrasion
- silicon has a positive effect on the elasticity, hardness and strength of steel
- SDS PLUS chuck
- carbide tip
- work with low vibrations
- 4 cutting edges prevent the drill bit from jamming in the reinforcement
- quadruple spiral efficiently and quickly discharges the material from the hole
- long service life
- Sizes of drills in the set: 5x110 mm / 6x110 mm / 6x160 mm / 8x160 mm / 10x160 mm
