The Apex Tool and Cutter Company   "APEX" Standard Tool Holders   FOR USE WITH ALL SHAPES OF ADJUSTABLE SERRATED TOOL BITS   All "APEX" holders are manufactured of the finest materials available. Most are DROP FORGED of nickel chrome alloy steel, heat treated for maximum toughness and durability where practical. A most rigid tool as the seat is made of DROP FORGED tempered steel. The seat protects the life of the holder and can easily be replaced if necessary, when damaged. The taper seat pulls the tool bit into position until it is securely locked on three sides. By mating serrations on the bottom of the tool bit and on the seat, tools can be adjusted in steps of .060 sideways. Thus, the tool bits are adjustable for wear and being lower in cost than solid tools, have the advantage of controlled costs on shop work. tool bits are made in many sizes for the light, medium, or heavy work and any one size is interchangeable in holders of the same numerical size for any type machine.   A tool bit can be changed without disturbing the holder thereby maintaining the original set up. (See separate sheets for tool bit details.) Standard size holders are listed but shanks of special dimensions or design can be furnished when desired.   HOLDER STYLE RECOMMENDATIONS   Straight Holders For Lathes, Planers, Shapers and Boring Mills.
