CGW 58037 is a high-grit pink aluminum oxide surface grinding wheel designed for heavy stock removal with a controlled finish. The wheel features a 12 inch diameter, 1-1/2 inch thickness, and a 5 inch arbor/shank size, with a Type 5 configuration and a PA-46H grain blend. The PA-46H designation indicates pink aluminum oxide, selected for its balance of cutting performance and durability on tool steels and hard alloys when used at appropriate feed rates. This wheel is intended to deliver fast, cool cutting, which helps minimize heat buildup on heat-sensitive materials during grinding operations.
Key construction details include the abrasive material and grit size: PA - Pink Aluminum Oxide, grain size 46, which is compatible with coarse to medium finishing requirements on tool steel and certain stainless grades at light to moderate feed rates. The H hardness rating suggests a relatively rigid wheel suitable for maintaining shape under load, contributing to consistent material removal and a predictable grind. The 12" diameter and 1-1/2" thickness provide substantial wheel mass for stable operation on surface grinding machines, while the 5" arbor size accommodates common grinding setups. The product is packaged as individual wheels with a box quantity of 2, aligning with workshop stocking practices.
This wheel is suitable for applications where a combination of rapid material removal and a controlled finish is needed, particularly on tool steels and hard alloys. When selecting this wheel, confirm compatibility with your grinder spindle, wheel guard clearances, and the machine’s RPM capability, noting the rated speed of 2220 RPM for this specific wheel. Proper dressing and truing are advisable to maintain the intended wheel geometry and finish.
