DUO-S AND QUADRO-L
VARIO DRILL BITS

 Exclusive Premium

DUO-S VARIO is the best premium 2-Cutter and QUADRO-L VARIO is an exclusive premium SDS-PLUS 4-Cutter.

DUO-S VARIO

The new DUO -S VARIO drill bits sets have new performance standards. It is the consequent further development of the over one million sold 4 PLUS drill bits. In terms of drilling speed the new DUO-S VARIO drill bit is up to 12% faster than the 4 PLUS drill bit and up to 25% faster than the competition. It is ideal to use with cordless hammers.

This proves the DUO-S VARIO drill bit will inspire and convince users of its qualities and it will be the most outstanding drill bit of this next generation.

Power Breaker

  • 1. Domolition effect
  • 2. Produce micro cracks in the driller material
  • 3. Generate noticeable greater drilling speed

Enlarged rebar chamfers

  • 1. Enlarged rebar chamfers(+35%)
  • 2. Prevents side tip damage when hitting rebar
  • 3. Reduce the likelihood of the drill bit jamming when hitting rebar

Centering Tip

  • 1. Ensures immediate spot drilling
  • 2. Prevents skidding on smooth surfaces

VARIO KVS-FLUTE
 

  • 1. Identified from its tapered shoulder geometry
  • 2. Thdereby giving it greater speed and break resistance(durability)

Reduced friction due to tapered shoulders for more speed

Best durability

QUADRO-L VARIO

QUADRO-L VARIO is the consequent further development of today's ZENTRO PLUS. It is a significant improvement of reinforcement drilling(up to 50%). It has a noticeable greater drilling speed(up to 20% speed increase). It is part of a logical product family for SDS-PLUS 2-/4-CUTTER.

The QUADRO-L VARIO drill bit will inspire and convince users of its qualities and it will be the most outstanding drill bit of the next generation.

4x90 degree Head geometry

  • 1. For absolute round holes
  • 2. Optimized drilling performance in reinforced concrete
  • 3. PGM conformity for accurately fitting dowel drill

Power Breaker

  • 1. Demolition effect
  • 2. Produce micro cracks in the drilled material
  • 3. Generate noticeable greater drilling speed

Enlarged rebar chamfers
 

  • 1. Enlarged rebar chamfers
  • 2. Reduced the likehood of the drill bit jamming when hitting rebar

Centering tip and short flute entrances

  • 1. Ensures immediate spot drilling
  • 2. Prevents skidding on smooth surfaces
  • 3. Fast dust removal because of large-volume flutes

4-fluted

  • 1. Large-volume flutes provides optimum between volume and break resistance
  • 2. Optimized core reinforcement for maximum of break resistance and vibrationless drilling performance

Vario-flute

  • 1. Identified from tis small tapered shoulder geometry there is a greate speed of the QUADRO-L VARIO through reduced friction.
  • 2. Identified from its bigger tapered shoulder geometry there is higher durability of the QUADRO-L CARIO nad best break resistance.
