The Armstrong Brothers Tool Com-pany of Chicago have been awarded amedal for their exhibit of lathe andplaner tool holders, at the recent Inter-national exhibition at Liege, company are the tool holder. THREE B.\R BORING TOOL, people and their three bar boring toolis a very serviceable article. A slight turn of one nut releases orfastens both bar and holder. Bars canbe changed as needed almost instantly,thus allowing the operator to use thestiflfest bar possible for each job withthe result that speeds and feeds can beincreased and time saved. The toolholder is very stiff and is made frombar steel throughout. The cutters are soheld that the strain of cut holds themtighter. The convenience of this late at-tachment is appreciated by many practicalmachinists who use them. Dutch State Railway Express.
