Fein JCM 200 U vs AJMU 137 PMQW
Hole Capacity
The Fein JCM 200 U Magnetic Drill offers a maximum hole capacity of 2 inches. This allows you to use larger annular cutters for heavy-duty applications on construction sites. In contrast, the Fein AJMU 137 PMQW AS has a maximum cutter diameter of 1-3/8 inches. While the AJMU handles up to 2 inches of cutter drilling depth, its narrower diameter limit restricts the size of holes you can drill in a single pass. If your work frequently requires large-diameter holes, the JCM 200 U provides the necessary clearance and capability that the cordless model cannot match.
Portability
Weight and dimensions significantly impact how easy these tools are to move around a job site. The Fein AJMU 137 PMQW AS weighs only 26.9 lbs, making it the lightest in its class. Its compact design measures 21 inches in length and 13 inches in width. The Fein JCM 200 U is much bulkier, measuring 24 inches by 24 inches with a height of 11 inches. The data does not list the weight of the JCM 200 U, but its larger physical footprint suggests it is less convenient for mobile use. For workers who need to carry their drill up ladders or across long distances, the AJMU is the clear choice.
Spindle Travel
Spindle travel determines how deep you can drill without changing the setup. The Fein AJMU 137 PMQW AS features an extended stroke range of 10-1/4 inches. This advanced double dovetail guide system enhances versatility for drilling, tapping, and reaming in various industrial applications. The data for the Fein JCM 200 U does not specify its spindle travel distance. Without this specification, you cannot compare the depth capability directly. However, the AJMU’s listed 10-1/4 inch range is substantial for most standard magnetic drilling tasks, offering a clear advantage in reach for deep-hole operations.
Motor Type
The internal motor construction affects longevity and maintenance needs. The Fein AJMU 137 PMQW AS is equipped with a brushless PowerDrive motor. This design is built for durability, capable of lasting over 300 hours of operation and delivering up to 60,000 precision-drilled holes. The Fein JCM 200 U data does not specify whether it uses a brushless or brushed motor. Brushless motors generally require less maintenance and offer longer lifespans. If you prioritize long-term reliability and reduced maintenance on a cordless unit, the AJMU’s specified brushless technology provides a distinct technical advantage.
Safety Features
Safety mechanisms are critical when working with powerful magnetic drills. The Fein AJMU 137 PMQW AS includes a tilt sensor shutoff that automatically stops the drill if it tilts or loses magnetic adhesion. This feature prevents accidents and ensures user protection in demanding conditions. The data for the Fein JCM 200 U does not mention any specific safety sensors or automatic shutoff features. While both units are designed for professional use, the AJMU provides explicit electronic safeguards against unsafe operating conditions, offering a higher level of built-in protection for the operator.
