Hilti has said that lower vibration and a reduced power-to-weight ratio are the two key performance developments in its new, next generation 8 kg combihammer.
The TE 80-ATC AVR features the company’s Active Vibration Reduction system which has cut the tri-axial measurement to 7.5 m/s², meaning an operative can drill 696 holes-per-day (based on a 25 mm diameter to 100 mm depth) before reaching exposure limit value (ELV).
In addition a drilling speed of 360 revolutions per minute (rpm), compared to an industry standard of 250-280 rpm, and a 1,700 watt motor achieves an impressive performance-to-weight ratio by creating a single impact energy of 11.5 joules and a hammering speed of 2,760 blows per minute.
Other improvements include a new, larger slip clutch and a unique air cooling concept, that reduces the working temperature of the tool and cuts dust intake. Improving both operator productivity and reducing maintenance and repair downtime.
Hilti’s Active Torque Control (ATC) triggers an immediate electronic safety cut-out if the drill bit becomes jammed. Worker health and safety is further improved with a Dust Removal Systems (DRS) available for drill bits, chiselling and coring.
The product is designed for hammer drilling in concrete, masonry and natural stone up to a 150 mm diameter using TE-Y and TE-YX drill bits. It can also be used to core in concrete and masonry up to 150 mm, and for mid-to-heavy chiseling.
