SONNLER Tungsten Electrode Sharpener Grinder for TIG Welding — 6 Sizes, 8 Angles, 10 Diamond Wheels, 3 CNC Mandrels

Portable Precision for TIG Welding

The SONNLER Tungsten Electrode Sharpener Grinder is a compact, handheld tool designed to deliver precise tip angles and repeatable results. Its lightweight design makes it easy to carry between jobs, while built-in guides help you set consistent angles without guesswork. The setup is straightforward enough for beginners yet versatile enough for seasoned welders who value speed and consistency.

What you get

• 1 electric grinder
• 1 tungsten electrode grinding head
• 10 double-sided diamond grind wheels (long-lasting material)
• 3 CNC mandrels for repeatable tip shapes
• 1 storage box
• 1 wrench
• 1 user manual
• 1 pin vise hand drill

Angle and size versatility

The kit covers 6 tungsten electrode sizes: 5/32 inch, 1/8 inch, 3/32 inch, 5/64 inch, 1/6 inch, and 0.040 inch. It offers 8 fixed holes for angles: 7.5°, 10°, 15°, 20°, 22.5°, 25°, 27.5°, and 30°. Tip-angle targets include 15°, 20°, 30°, 40°, 45°, 50°, 55°, and 60°, giving you options to tailor tips for different joints and positions.

Easy operation and setup

• Fixed holes let you grind the chosen angle by simply inserting the tungsten electrode into the corresponding hole, with no height re-adjustment needed.
• Offset compensation keeps the tip centered on the grinding point for consistent results across sizes.

Usage tips and safety

Work in a well-ventilated area and wear protective gear as needed. The compact design is ideal for mobile setups, but always treat grinding with care to keep both you and the workpiece safe. When not in use, store the kit in the included box to protect the components.

In real jobs, users report less time spent adjusting tools and more time welding, thanks to predictable tip angles and repeatable shapes. The included wheels and mandrels are designed to withstand repeated grinding, helping you keep the same setup across multiple electrodes.
