finishing a thing of the past. ACM Cut Off Saws and Wheels are specifically designed for the delicate nature of precision cutting and therefore ACM Products Co. only stocks Non-Reinforced Wheels. (Strict safety standards are met with wheel covers and safety shields.) Reinforced wheels have a higher safety rating than Non-Reinforced wheels because they are interwoven with filaments however, they do not cut as cleanly as non-reinforced wheels. Non-reinforced wheels provide a more “finished” cut and what little burr remains is nominal. When used within the proper guidelines (fixed saw base, enclosed wheel covers, and material clamps) non-reinforced wheels are considered safe to use also. Because there are no filaments interwoven into the wheel, this permits the use of much thinner wheels particularly when waste is a factor, or when cutting precious metals. ACM Products Co. stocks wheels as thin as .008” for those critical cutting applications.
Standard stock items come in aluminum oxide, or silicon carbide grits in a rubber or resin bond. To aid in determining the proper wheel for specific cutting applications, please see the following explanations to help in understanding ACM nomenclatures:
4AEG-90-32, 4AUB-120-15, 4CUT-240-08, 5DMC-100-25
The first number (4 or 5) stands for ACM Wheel Diameter in inches.*
The first letter (A, C, or D) stands for the abrasive material:
A= aluminum-oxide C= silicon-carbide D= diamond
The second letter (U, E, or M) stands for the type of bond used to adhere the abrasive material:
U= Rubber E= Resinoid M= Metal
The third letter (B, D, G, H, or T) indicates the hardness of the bond from A to Z. The softer bonds being closer to “A” and the harder bonds being closer to “Z.”
The second number (60, 90, 120, etc.) is the grit size; “60” being the most coarse to “240” being a very fine grit for a smoother finished cut. Coarse grit provides a faster cut, finer grit provides a smother finish (less bur).
The third number (08, 10, 15, etc.) is the wheel thickness in thousandths. ACM stocks Cut Off Wheels in thicknesses from .008 to .062 thousandths. To provide for an even smoother finish, we recommend cutting wet whenever possible.
