CMI vs GWW Comparison

Cummins is a leading manufacturer of diesel and other engines used in heavy- and medium-duty commercial trucks, off-highway equipment, and locomotives, in addition to prime power and standby generators. The company also sells powertrain components, which include filtration products, transmissions, turbochargers, aftertreatment systems, and fuel systems. Sales are approximately 60% US and Canada and 40% rest of the world. Much of Cummins' foreign sales (China, India, and so forth) are through joint ventures. The company operates 650 distributors and over 19,000 dealer locations across 190 countries. Cummins' business model is unique as it competes with many of its heavy-duty truck manufacturer customers, which also make their own engines.

Founded in 1927, W.W. Grainger originally distributed various motors via a mail-order catalogue. Over the course of the 20th century, the firm expanded into new industrial product categories and launched its first digital catalogue in 1995. Today, the company organizes itself into two segments focused on different customer bases. Its larger segment, high-touch solutions, offers a vast array of maintenance, repair, and operations, or MRO, supplies and bespoke inventory management services to larger businesses. Its smaller segment, endless assortment, operates two online platforms, Zoro and MonotaRO, that offer comprehensive catalogues of MRO supplies to smaller businesses. Grainger has operations throughout the world but primarily generates sales within the US.
