CONCRETE DRILL BITS (4-CUTTERS)

CONCRETE DRILL BITS (4-CUTTERS)

4 cutter type comes with SDS MAX shank, its 4 cutting edges design will make the drilled hole smoother and rounder. Its smooth and wide grooves will leave concrete dust easily and rapidly. Impact power will transmit softly to the head pit and it will reduce stress to the user.

1. Dynamic drill bit head with unique cutting geometry

The improved quality of the head design is not only reflected by improved life expectancy but specifically through the faster drilling.

• Special primary cutting geometry
• Centering point for exact spot drilling
• Reduced friction and centralized alignment in drilled hole
• Secondary cutters protect drill bit in the event of reinforcement collision
• Improved soldering process of Carbide chip with flute
• Shortened spiral windings and conical shaped dust tracks for extra fast material removal into the high volume double flute

2. Optimized spiral shape for maximum hammer force

The high volume, double helix of the 4 cutter is produced with the patented, high performance, reinforced core KVS flute.

The practical advantages:

• Maximum energy transfer
• Optimized vibration control
• Resistant to torsion forces
• Reduced noise emissions
• Less stress for man and machine
