Inabra - Abrasivos e Ferramentas Ltda.

INABRA's subsidiary factory manufactures and markets cutting tools, work rest blades for centerless grinders, and industrial knives – all featuring tungsten carbide inserts. The factory is divided into the following sectors: Manufacturing, Welding, Maintenance, and Quality Control.

Our products are manufactured with an SAE 1045 steel body. Other materials can be used upon customer request. We stock several different types and gauges of steel.

Because INABRA uses high-frequency welders, steel and hard metals do not need to be excessively heated. The silver solder we use in our welding process has a low fusion point and welded materials suffer no loss of strength.

We manufacture, recondition, and sharpen work rest blades (up to 1,500 mm in length) for centerless grinders. We manufacture industrial knives (up to 580 mm in length) and sharpen industrial knives (up to 3,000 mm in length).

All machining tools are manufactured according to international standards and comply with the criteria of the following institutions: ASA, SMS, DIN, and ISO.

INABRA is a pioneer in the field of work rest blades for centerless grinding.

We stock enough hard metal to meet market demands, and we are able to manufacture and recondition any work rest blade found in today’s market. The company has become a specialist in this field. We are also working to manufacture hard metal “trilateral knives,” which Brazil currently imports from foreign markets.

Our Manufacturing sector is equipped with lathes, planes, drills, and mills – as well as grinders, sharpeners, an abrasive jet machine, and a furnace for tempering steel.

The Welding sector has both a high-frequency welder and oxy-acetylene welding equipment.

The Quality Control sector is equipped with a precision profile projector and a variety of measuring instruments needed for product testing and inspection.

The subsidiary factory sends customers an Inspection Report after all jobs. This report provides customers with a description of services rendered on their products.

INABRA’s machinery and equipment can sharpen the hard metal knives (up to 3,000 mm in length) used by the paper industry, printing facilities, and packaging plants. We can also sharpen trilateral cutting machines knives, rotational Widia knives (for rotogravures), machining tools, and other tools with tungsten carbide inserts.
