An extremely versatile tool that can be used as an Angle Finder, Centre Locator & Levelling Gauge.
Tool is designed to give accurate reading of angles for full 360° via an extremely sensitive & balanced needle.
The protractor body is encased in cast aluminium shell with legs made from cast iron. The Vee bases have inbuilt magnets that exert magnetic pull both within the Vee & across the bottom surface of the legs of the Vee. This allows the tool to attach instantly to any ferrous surface “” round or flat for accurate measurement of angles.
The Vee bases are precision ground and the centre pin shows the middle point for locating centres on round objects. Can also be used for levelling work on workpieces.
This tool has unlimited applications and can be used in:.
– Tool rooms & machine shops for determining angles on shapers, milling machines & grinders. For determining centre of round stocks, & for drilling operations.
– Welding Shops.
– Construction & Maintenance sites.
– Auto & Truck shops, especially for checking angles of die lines.
Angle Accuracy: within ± 0.5°.
Manufactured from hardened and polished stainless steel, all gauge surfaces are accurately ground.
It is most useful for checking tool angle while cutting threads in metal turning lathes. The angle on the thread cutting tool is checked on the V slots in the gauge.
Relief at the end of each slot enables proper seating of the cutting tool in the slot thus ensuring correct angle.
The gauge clearly indicates 55° for Whitworth and BSF Threads; 47-1/2° for BA Threads, 60° for Metric and American National Threads and 14-1/2° for Acme threads.
Manufactured from stainless steel, these small flat gauges have angles of 55° and 60°.
Very useful for grinding and setting thread cutting tools, these may also be used for checking the pitch of threads through the permanently deep etched graduations in 14ths, 20ths, 24ths and 32nds of an inch.
These gauges meet the American National or US 60° and Whitworth or English 55° specifications.
