The most important factor while choosing a straight grinder is to decide on the right kind of grinder required for the project. While opting for this type of grinder, one needs to consider the comfort Level of the user while in application. The rotation speed of the grinder is very high and kickbacks while in operation, can prove to be dangerous. Look for the grinder with an impact absorbing tool, and a coated spindle housing that would not make the machine hot. Moreover, the body of the tool should be in such a way that the user can have a steady hold on it.

Straight grinders should be compatible with different types of wheels such as grinding and cutting wheel. Changing of the wheel should be extremely easy, consuming minimal amount of time and effort. Other accessories and features such as the cord length, wrench, arbor nuts, flanges, etc should be considered while purchasing. The hardened helical-cut alloy steel gear and shaft ensure longer durability of the tool.

If you opt for the die grinder, the most important aspect to be considered is the rpm. Also, consider the power-to-weight ratio while purchasing the tool. The collet capacity is the next feature of the grinder that needs to be taken into account. Usually the maximum collet capacity of die grinders is ¼ inch, but can vary. The power rating of straight grinders varies from 0.5hp to 0.8hp. Some manufacturers provide maintenance accessories with die/straight grinders. Some reputed manufacturers of straight/die grinders include Astro Pneumatic, Ingersoll-Rand IR, Chicago Pneumatic, Makita, Campbell Hausfed, DeWalt, Mechanics, Milwaukee, TD Industrial, Viking, Porter Cable, Bosch, and Flex.
