3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder Head TIG Welding Tool 24 Guides w/Dust Housing, Healthy Version Tungsten electrodes of varying diameters are typically used in conventional welding procedures practiced in a wide variety of industries. During such procedures, an arc is established between the metal to be welded and the end, or point, of each electrode. The electrode point becomes worn or damaged over time, resulting in inadequate or interrupted current transmission. As the quality and efficiency of welds are highly dependent upon the condition of the electrode point, it is important that the point be dressed, or reshaped and sharpened, as needed during welding operations. After much research and development as well as a lot of users' feedback, now, The Fourth Generation is already on the market - 3mirrors Tungsten Electrode Sharpener Grinder Angle Controller TIG WIG Welding Tool Grinding for 040 1/16 5/64 3/32 1/8 5/32 every 4 tips 30° 36° 45° 60° (The problem of the 2 sets of hole direction and hole spacing has been improved) Dust cover design to get free health and convenience. Tungsten is heavy metal, and most tungsten needles contain about 2% of weak radioactive elements, such as tantalum tungsten needles, tantalum tungsten needles, and pure tungsten needles. As the pictures show.The new design has 6 sizes, each size can ground 4 kinds of tip Angle, a total of 24 Angle holes, suitable for a wider range of tungsten needle sizes.Due to a more accurate Angle control design, the cutting point is offset to the center of the grinding bevel rather than the top. INSTALLATION STEPS : 1: Put on the 2 O-rings to the aluminum main body to ensure the Dust cover can be fixed and prevent dust leakage; 2. Install the mandrel to a Diamond wheel; 3. Screw the aluminum main body on Rotary Tool; 4. Set the grinding wheel and mandrel in the collet of your rotary tool; 5. Adjust the height of the Diamond wheel, Make sure the grinding wheel is parallel to the edge of the control head; 6. Push the transparent Dust cover on the control head; 7. If the dust cover is too tight to push, You could apply some oil (Whatever Engine oil, grease or Dishwashing liquid) on the O-ring so the cover will be easy to install; 8. Start grinding different angles of tungsten needle, according to your needs; 9. After grinding, Centralized processing of the tungsten power, avoid trouble, convenience and healthy. It's an ALUMINUM Tungsten Electrode Sharpener Grinder Head without a rotary tool/Drill, it fits most all Rotary Tools with a 3/4-12 thread including Black and Decker, Milwaukee, Bosch Dremel and More!

After much research and development as well as a lot of users' feedback, Here is it. 3mirrors Tungsten Electrode Sharpener Grinder Angle Controller TIG WIG Welding Tool Grinding for 040 1/16 5/64 3/32 1/8 5/32 every 4 tips 30° 36° 45° 60° (The problem of the 2 sets of hole direction and hole spacing has been improved) Widely applicable sizes. The Lastest design is available for 6 sizes of tungsten needles: 040", 1/16", 5/64", 3/32", 1/8", 5/32" (1mm, 1.6mm, 2mm, 2.4mm, 3.2mm, 4mm); Each size can grind 4 tip angles: 15° 18° 22.5° 30° (30° 36° 45° 60°). Multi-Angle hole alignment, tungsten needle insertion Angle and grinding process more refined. Upgrade Parts: The O-ring groove of the old model is not completely suitable, so three sets of different o-rings are needed. The upgraded model only requires a set of 50mm * 1.9 O-rings with suitable built-in elasticity. The direction of the tapered hole in the old model is the same as the rotation direction of the grinding wheel, resulting in the tungsten needle being sucked in during grinding. The upgraded model has changed the direction of the replaced holes, and all adjustments have been made to make the hole spacing more evenly distributed without crossover; The cutting groove of the old model is too small, so the 4.8mm tungsten needle cannot penetrate; the upgraded model has expanded the incision. IMPORTANT: According to feedback from some first-time users, if the grinding wheel cannot be aligned with the cut during the installation process, or the grinding wheel does not reach the expected position, it may be that the chuck you are using is too high and exceeds the height of the mandrel installation. At this time, please replace a chuck with a height not exceeding 34mm, so that the grinding wheel can be adjusted in a proper position. 4 Holes w/Screws ALUMINUM Tungsten Electrode Sharpener- Special Edition 24 Holes w/Dust Housing ALUMINUM Tungsten Electrode Sharpener- Healthy Edition 12 Holes Multi-Angle ALUMINUM Tungsten Electrode Sharpener- Starter Edition 4 Holes w/Screws ALUMINUM Tungsten Electrode Sharpener and Rotary Tool 24 Holes w/Dust Housing ALUMINUM Tungsten Electrode Sharpener and Rotary Tool 12 Holes Multi-Angle ALUMINUM Tungsten Electrode Sharpener and Rotary Tool Buying Options Buying Options Add to Cart Add to Cart Add to Cart Add to Cart Customer Reviews 4.4 out of 5 stars 491 4.4 out of 5 stars 161 4.4 out of 5 stars 639 4.0 out of 5 stars 141 4.2 out of 5 stars 275 4.2 out of 5 stars 275 Price — no data $75.67$75.67 $38.98$38.98 $84.99$84.99 $118.99$118.99 $79.99$79.99 Aluminum Made ✓ ✓ ✓ ✓ ✓ ✓ Offset Angles 10°, 15°, 20°, 22.5° 15°, 18°, 22.5°, 30° 15°, 20°, 15°, 20° 10°, 15°, 20°, 22.5° 15°, 18°, 22.5°, 30° 15°, 20°, 15°, 20° Grinding Wheel Size & Number 25mm x 5 35mm x 5 25mm x 5 25mm x 5 35mm x 5 25mm x 5 With Rotary Tool x x x ✓ ✓ ✓ Features With 4 brass tungsten guide rails With a Dust Housing to keep healthy work Simple and easy to use is most popular With 4 brass tungsten guide rails With a Dust Housing to keep healthy work Simple and easy to use is most popular
