Universal bevel protractor with vernier scale — reads angles to 5 arcminutes for precision machine shop and tool room work. Essential for dovetail setup, chamfer inspection, and cutting tool geometry checks. In stock at Multi Trade Combines, AT Road, Guwahati.
A bevel protractor is a precision angular measuring instrument used in machine shops, tool rooms, and quality inspection facilities to measure angles on machined workpieces, cutting tools, jigs, fixtures, and assembly setups. The universal bevel protractor with vernier scale — the most common type used in production precision work — consists of a graduated circular main scale and a moveable blade with a vernier vernier reading to 5 arcminutes (5') of arc, giving the operator precise angular readings in any of the four quadrants without mathematically correcting for the position of the blade.
In a conventional or CNC machine shop in Guwahati or across Assam, the bevel protractor is used for: checking the included angle of a drill bit or lathe cutting tool before regrinding; measuring the angle of a dovetail or V-guide on milling machine slides; inspecting the chamfer angle on turned or ground components; setting up compound slide or taper attachment angles on a lathe; and inspecting the blade angle on shaper and planer tools. It is also used by woodworking machinery setters, pattern makers, and sheet metal workers for accurate bevel and miter setups.
The instrument's durability and zero dependence on batteries or electronics makes it reliable in workshop environments where digital instruments risk damage from coolant, swarf, or oil contamination. Mitutoyo and Insize bevel protractors — both stocked by Multi Trade Combines — are constructed with hardened steel blades and precision-ground scales that maintain their accuracy over years of workshop use. Multi Trade Combines supplies the full range of precision measuring instruments from AT Road, Guwahati, with shipping to precision engineering facilities across Northeast India.

CNC and conventional machining workshops in Guwahati's industrial estates, tool room departments in manufacturing plants, quality control labs at precision component suppliers to ONGC, OIL, and defence establishments in Assam and Nagaland, and technical training institutes (ITIs and polytechnics) use bevel protractors as part of standard precision measurement training and production inspection.
Pairs well with: vernier caliper, outside micrometer, feeler gauge set, and dial gauge for a complete machine shop measurement kit. All available at Multi Trade Combines.
A bevel protractor measures the angle between two faces of a workpiece or a tool setup — for example, the angle on a dovetail slide, a chamfer on a turned component, the included angle of a cutting tool, or the blade set angle on a shaper or planer. The vernier scale on a universal bevel protractor gives readings to 5 arcminutes (5') of arc, which is sufficient for tool room and general precision workshop use. It is an essential inspection tool in any CNC or conventional machining setup.
A standard vernier bevel protractor reads to 5 arcminutes (0.083°). For most precision machining and tool-making applications — dovetails, angular turning, gear cutting setups, and grinding fixture setups — 5-arcminute resolution is adequate. For applications requiring finer angular measurement, an autocollimator or digital angle gauge may be required. Multi Trade Combines stocks both vernier and digital angle measurement instruments at AT Road, Guwahati.
