Dynabrade Die Grinders (Straight-Line) For Welding & Metalworking

Dynabrade Die Grinders offer a wide range of speeds to suit our end users abrasive selection. Models use a governor-controlled, gearless motor for where consistent speed under load is key.

1 hp Straight-Line Die Grinders

• Gearless motors have fewer moving, wearable parts which reduce maintenance and downtime in your process.
• Governor-controlled motor maintains speed under load, which is ideal for use with carbide burrs that need consistent speed to prevent clogging.
• Operators experience an ergonomic tool with less sound and vibration when using a gearless tool.
• All models include 1/4″ and 6mm inserts. Collet design also allows for optional 3/8″ insert.

.5 hp Straight-Line Die Grinders

Dynabrade Die Grinders are found in a variety of applications in large part because of the versatility a collet attachment provides. Our Die Grinders offer a range of speeds and collet capacities that accept abrasives such as mounted points, burrs, and expander wheels with coated abrasives and more!

.4 hp Straight-Line Gearless & Planetary Geared Die Grinders

All models include 1/4″ and 6mm inserts. Collet design also allows for optional 3/8″ insert.

Planetary Geared

Slow Speed – High Torque

Features higher torque levels and a broader power range. Planetary gears are in-line speed reduction gears, the greater the reduction, the higher the torque levels.
Model 47200 950 RPM
Model 47201 3,200 RPM
Model 47202 5,500 RPM

Gearless Models

Consistent Speed – Lower Vibrations

Motor is gearless with less wearable parts, ensuring reduced maintenance and less downtime. Gearless tools have lower vibration levels due to the omission of transmitting power through gears.
Model 48360 20,000 RPM
Model 48325 25,000 RPM
Model 48327 30,000 RPM
