Title
(EN) PNEUMATIC ROTARY TOOL
Abstract
(EN)

A pneumatic tool includes a plastic grip. The grip includes an outer layer of soft material overmolded onto the plastic grip. The outer layer is of a one-piece construction and covers substantially an entirety of the grip. In a method of assembling a pneumatic rotary tool, a plurality of bolts are inserted through an end cover and a housing of the tool. The bolts are threaded into a clutch casing, wherein the bolts draw the end cover toward the housing and the housing toward the clutch casing so that the end caps and support sleeve of the air motor are compressed within the housing to fully seat the end caps onto the support sleeve so that the motor. The housing and the end cover cooperate to hold the air motor in proper alignment within the tool.
