Barcor Chamfer Gage
made in USA 
This chamfer checking dial gage will give you a direct reading of the outer diameter of a chamfered hole. Two forms are available: for chamfers with an angle of less than 90° and for chamfers with angles from 90° to 127° The standard dial indicator is graduated in .001" but also available with .0001" digital or .0001" mechanical graduations. The accuracy for reading chamfers is ±.001" on 0-90° models and ±.002" on 90-127° models, regardless of which indicator you use. The base of the Chamfer Gage is manufactured by Barcor (USA) but the dial indicator varies from supplier to supplier. You'll most often find this tool with a Starrett indicator or a CDI indicator, usually with a vanity dial. That's the case with the SPI Chamfer Gage, Starrett Chamfer Gage and the Dyer Chamfer Gage for example. It's a sturdy gage with a cleverly simple design. It does require "mastering" and this is done as follows: on the back cover of the gage you'll find the words "Set To" followed by a value, such as .020. Now it's a matter of setting the gage to this value while it's on a surface plate. We suggest you inscribe this value into the metal or plastic back cover because the label will eventually wear off. Beyond this, no other masters are needed. |
