3mirrors Aluminum Tungsten Electrode Sharpener Grinder Head for TIG Welding – 5x 25mm Double Diamond Wheels, 2x Connecting Rods

Overview

The 3mirrors Aluminum Tungsten Electrode Sharpener Grinder Head is a compact, purpose built accessory designed to streamline TIG welding prep. It fits most rotary tools with a 3/4-12 thread, and note that the package does not include a rotary tool or drill. Crafted from upgraded aluminum alloy and finished with CNC precision, this sharpener balances durability with light handling for demanding work environments.

Key benefits come to life when you start using it: reliable tip shaping, efficient wheel usage, and helpful features designed for professional workflows. The kit includes five 25mm double diamond wheels and two connecting rods to cover common needs, helping you stay prepared for a range of electrode sizes and angles without constant tool swaps.

Precision grinding options for tungsten tips

The sharpener supports two tungsten sizes and two tip angles per size, offering four hole configurations: 1/16 inch at 15°, 1/16 inch at 20°, 3/32 inch at 15°, and 3/32 inch at 20°. Ground angles translate to different tip profiles (for example, 15° becomes a 30° ground tip, and 20° becomes a 40° ground tip), giving you flexibility in form and performance. Each type includes three holes designed to grind on different circles with a goal of reducing diamond wheel wear while keeping the tip geometry aligned.

• Two sizes and four hole types enable versatile tip preparation
• The three holes per type help balance wheel usage and extend wheel life

Smart, easy-to-use design

The main body weighs about 87 grams, delivering a light yet sturdy platform that is easy to maneuver. All holes are fixed, enabling a reliable offset compensation for each hole size so the tungsten tip center stays on the grinding center point. This helps keep lines as straight as possible on the tip and minimizes guesswork during setup.

• Lightweight yet precise construction for daily use
• Fixed holes enable stable offset compensation
• Uniform hole height simplifies setup and reduces re-adjustments

Cut-off port and durability

The tungsten cut-off port lets you refresh worn or contaminated tips, extending usable life without swapping to a new tungsten piece. Designed for high-temperature environments, the tool uses CNC-finished aluminum alloy to endure daily wear. The note for buyers: the 3mirrors brand represents the original design, and authentic purchases help ensure core data integrity.

Who this is for

Professionals who value efficient prep, predictable tip geometry, and durable construction will find this sharpener a useful companion in the workshop. While performance can vary with technique and tooling, the features are oriented toward repeatable, practical results rather than guaranteed outcomes.
