Abstract: A health and safety handle embodied as a multi-purpose rail-gripping device comprises a main handle member ergonomically shaped to be grasped by a user/rider, a rail-gripping arm connected to a first end of the handle, and a holder that is movable relative to the main handle member between a stowed position and a deployed position to hold an object while the main handle member is being grasped. The rail-gripping arm has a gripper to grip a grab rail, pole or bar in a public transit vehicle such as a bus, train, subway, streetcar) to stabilize the rider while isolating the rider's hands from contaminants or health hazards potentially present on the rail/pole/bar. The handle may also include a hook for suspending objects (e.g. backpack, bag, umbrella, etc.). The handle may include magnetic and/or mechanical retention elements for retaining one or multiple other objects/accessories, e.g. beverage container, smartphone or other items.

Abstract: A rotational tool includes a cutting head and a basic body. The cutting head includes a cutting portion including a chip flute and at least one of a cutting edge and an insert seat, where the chip flute is located before the at least one of the cutting edge and the insert seat in a rotational direction of the cutting head. A coupling portion is located axially rearward of the cutting portion relative to a cutting end of the cutting head, and is configured to couple to the basic body. A coolant slot extends axially and opens at an external radial surface of at least a portion of the cutting head.
