Hammer Drill Bit 4 Cutter
No hooking in and running off centre
The symmetrical 4 x 90° cutting edge geometry prevents the hooking in or running off centre of the drill bit when striking reinforcement or hard pebbles in concrete.
Perfect drilling properties
• Head geometry that is tailored to the drill bit diameter.
• 5-16 mm: One-piece carbide element for a high degree of stability the maximised surface for connection with the steel body
• 18-32 mm: Multi-piece cemented carbide element for faster drilling progress and improved buffering of the torsional forces thanks to the trisection design
Optimum guidance in drilled hole
The drill geometry with 4 cutting edges and 4 spirals.
Constant drilling speed
Special head geometry
Iron reinforcements may only be drilled through with permission from a structural engineer. With long drill bit lengths, pre-drill using a short drill bit of the same diameter.
