What Makes This Different?
Straight vs. Angle: Unlike an angle grinder where the disc is at a 90° angle, a Straight Grinder (often called a horizontal grinder) has the spindle in line with the motor. This is specifically for reaching into deep cylinders, pipes, or internal welds where a standard grinder won't fit.

Lower Speed, Higher Torque: At 5,300 RPM, it rotates much slower than the 13,000 RPM of your previous 100mm model. This lower speed is essential for larger 125mm wheels and polishing tasks to prevent burning the material or "glazing" the abrasive.

Significant Weight: At 4.3kg, it is double the weight of the ASM10-100S. This weight is actually an advantage here; it provides the "deadweight" needed to keep the tool steady while polishing or grinding long, flat surfaces.

The "SHF-9750 Polisher Screw Head"
The SHF-9750 is likely the specific spindle adapter or attachment head included in this combo.

Purpose: It converts the grinder's output to accept Screw-on polishing accessories (like wool pads, felt bobs, or flap wheels).

Application: This turns the heavy-duty straight grinder into a dedicated Long-Reach Polisher. It’s a favorite for stainless steel fabricators who need to polish the inside of tanks or large architectural metalwork.

Comparison at a Glance
ASM10-100S (1020W): The "Sprinter." Fast, light, for cutting and surface grinding.

ASS125B (710W): The "Distance Runner." Heavy, stable, for internal grinding and deep-reach polishing.
