A removable nosepiece (100, 200, 300) for a chuck (20, 20') or other similar tool holder has an outer ring (110, 210, 310) of relatively hard and inflexible material such as plastic and/or metal and an inner ring (120, 220, 320) of relatively soft and flexible material such as rubber. The outer ring releasably holds the nosepiece on the distal end of the chuck or other tool holder. A tool is inserted into the chuck or tool holder through a central aperture in the inner ring. The inner ring engages the sides of the tool to help keep dust and debris out of the chuck or tool holder. The nosepiece can be removed and replaced when it becomes worn (e.g., when the inner ring is no longer functional).
Embout démontable (100, 200, 300) pour mandrin (20, 20') ou autre porte-outil similaire comportant un anneau extérieur (110, 210, 310) fait d'un matériau relativement dur et peu flexible tel que du plastique ou du métal et un anneau intérieur (120, 220, 320) fait d'un matériau relativement tendre et flexible tel que du caoutchouc. L'anneau extérieur sert à maintenir réversiblement l'embout sur l' extrémité du mandrin. On engage un outil dans le mandrin à travers l'ouverture centrale pratiquée dans l'anneau intérieur. Ce dernier qui enserre les côtés de l'outil contribue à empêcher la poussière et les débris de pénétrer dans le mandrin. L'embout peut se démonter et se remplacer lorsqu'il est usé (c.-à-d. quand l'anneau intérieur ne joue plus son rôle).
