1.Versatility for every job
GX 75 belt grinders feature high power motors providing outstanding capacities to assure maximum grinding production. The GX 75 and GX 75 2H also exhibit minimal vibration characteristics during operation, due in part to a patented belt tensioning system. Operator production and comfort is a standard feature with GRIT GX belt grinders.
Whether grinding, weld seam polishing, chamfering, debur ring, or flat sanding – with Grit work is: efficient, productive and especially, cost effective!
2.Optimal flat grinding
Flat grinding is another standard feature with GRIT machines. A 3" x 16 ⁄ " (75 x 420 mm) height adjustable grinding table for flat work is standard on both GX 75 and GX 75 2H.

1. Quick brilliant results all around
Perfect surface quality and high process speeds on pipes and shafts are no problem for the GXC cylindrical grinding module. Even commercially available fleece belts can be used in connection with the GX 2H basic unit. The feed rate
can be adjusted for various materials through an infinite range up to 6.6 ft/min (2 m/min).
2. Always on the right track
Quality surface finishes are always assured with the GXC. Included are two nylon and one brass guide rail for all your finishing needs. The brass rail is used for wet or dry finishing on rough surfaces such as corrosion, scale, etc. The nylon rail is used for wet finishing on sensitive materials when a highly polished surface is required.
3. GXW for wet grinding
There are several arguments for wet grinding using the GXW cooling lubricant module: A liquid coolant captures the metal dust, which increases the service life of the sanding belts; the finishing results are noticeably improved; and thanks to the reduction of heat generated during grinding the corrosion risk for stainless steel pipes is reduced. A self contained, closed circulation system minimizes coolant consumption.
