Product Features

The TR-3A is the same type of guard as the TR-2, with a much larger screen. This guard works very well on drill presses that have very wide or geared head drill presses, also works great on drill presses with long spindle shafts that usually are able to accept a Morse taper tooling. This guard can also be used on small radial drills. The screen is made out of impact resistant polycarbonate (Lexan™) material.  Polycarbonate is well known for its high impact strength.  Most importantly, this safety guard includes a built-in electrical safety interlock switch which is tamper resistant.  The safety interlock switch ensures that the safety guard is in place before the machine can be operated.

This guard will help prevent ejections from accidentally leaving chuck keys inside the drill chucks.  Customers can also buy self-ejecting chuck keys for added safety.  Click here to see our chuck key selection.

These shields meet or exceed OSHA, ANSI and CSA standards for machine safety guarding.

Why Have Safety Interlocking?

An electrical safety interlock prevents the machine from operating when the shield is opened.  This safety guard features an electric switch that disables the machine’s motor.  The switch is made in such a way as to prevents easy bypass of the interlock switch.

When we do on-site visits, we often see safety shields moved to the side and never put back on the machine.  An interlock is a simple solution to prevention of safety guard misuse or removal.
