BETA 1933L Pneumatic Straight Die Grinder 200W 25000 RPM 6mm Collet

For professionals who demand precision in tight spaces, the BETA 1933L pneumatic straight die grinder delivers a compact 200W output at an impressive 25,000 RPM no-load speed. Unlike bulky electric grinders, this air-powered tool stays cool during extended use and offers a slim, straight body that reaches where angle grinders cannot. The 6 mm collet accepts a wide range of mounted points and carbide burrs, making it ideal for deburring, porting, mold finishing, and light weld dressing.

Highlights

• Pneumatic power: 200W output with 25,000 RPM for fast material removal
• Straight design: slim aluminum housing for access to confined areas
• 6 mm collet: secure grip on standard shank accessories
• Rear exhaust: directs air away from workpiece and operator
• Safety lever throttle: prevents accidental starts
• Low vibration: 2.5 m/s² for comfortable long-duration use

In daily use

Connect the 1933L to a clean, dry air supply at 6.3 bar (90 psi) with a 10 mm (3/8") hose. The rear exhaust keeps chips and air blast away from your work area, while the safety lever requires deliberate pressure to engage. At only 80 dB(A) sound pressure, it is quieter than many comparable grinders, reducing fatigue in busy workshops. The aluminum body dissipates heat efficiently, and the straight handle allows a pencil-grip or palm-grip for precise control.
