3. Technical description

The Hilti DX 351BT and DX 351BTG are powder-actuated fastening tools for driving X-BT threaded studs into steel.

The tool works on the well-proven piston principle and is therefore not related to high-velocity tools. The piston principle provides an optimum of working and fastening safety. The tool works with cartridges of 6.8/11 caliber.

Piston return and cartridge transport is fully automatic.

This permits fastenings to be made very quickly and economically with nails and threaded studs.

As with all powder-actuated tools, the tool, magazine, fastener program and cartridge program form a “technical unit”. This means that optimal fastening with this system can only be achieved if the fasteners and cartridges are specially manufactured for it, or products of equivalent quality, are used. The fastening and application recommendations given by Hilti are only applicable if these conditions are observed.

The tool features 5-way safety – for the safety of the operator and bystanders.

The piston principle

1

The energy from the propellant charge is transferred to a piston, the accelerated mass of which drives the fastener into the base material. As approximately 95 % of the kinetic energy is absorbed by the piston, the fastener is driven into the base material at much reduced velocity

(less than 100 m/sec.) in a controlled manner. The driving process ends when the piston reaches the end of its travel. This makes dangerous through-shots virtually impossible when the tool is used correctly.

17


en

The drop-firing safety device 2 is the result of coupling the firing mechanism with the cocking movement. This is designed to help prevent the Hilti DX tool from firing when it is dropped onto a hard surface, no matter at which angle the impact occurs.

The trigger safety device 3 ensures that the cartridge cannot be fired simply by pulling the trigger only. The tool can be fired only when fully depressed.

The contact pressure safety device 4 requires the tool to be fully depressed with a significant force. The tool can be fired only when pressed fully in this way.

In addition, all Hilti DX tools are equipped with an unintentional firing safety device 5 . This prevents the tool from firing if the trigger is pulled and the tool then pressed against the work surface. The tool can be fired only when it is first pressed

쩸 correctly and 쩹 the trigger then pulled.
