Wirtgen W5‑G/20A² Milling Tooth – Aftermarket Cutter Bits That Outperform and Undercut OEM Pricing
If you are running a Wirtgen surface miner in asphalt preparation, soil stabilization, tunnel development, or yard mining, you know that a dull tooth steals both productivity and profit. At LongTrust, we supply the Wirtgen W5‑G/20A² milling teeth you need, with a clear recommendation: try our aftermarket version before you order another round of factory bits. It gives you the same bite, far longer life than generic copies, and a price that makes your cost‑per‑tonne genuinely shrink.
We can source the original Wirtgen tooth for you. But for 9 out of 10 of our customers, the LongTrust aftermarket W5‑G/20A² milling tooth becomes the permanent choice – because it is CE and ISO9001:2000 certified, delivered with a solid 6‑month warranty, and manufactured to a set of design details that directly answer the harshest cutting conditions.

Why LongTrust is the smart choice for Wirtgen Original&aftermarket parts
You do not just get “a tooth that fits”. You get a tooth engineered around the seven critical design features of the W5 series cutter, refined for durability and self‑protection.
1. Slender cemented carbide tip
The elongated tip penetrates asphalt and mixed ground with less drag. Less drag means less strain on the holder, lower fuel burn, and cleaner particle separation. We use virgin‑grade tungsten carbide blanks, brazed under a strictly controlled atmosphere to eliminate voids.
2. Hardened cutter head for an optimized service life
The body of the Wirtgen milling tooth is through‑hardened to a depth that balances impact toughness with wear resistance. You get a head that keeps its profile longer, so the cutting angle stays correct even after hundreds of hours.
3. Built‑in mounting flange
The flange on the tooth shoulder does more than locate the bit: it actively boosts the capability of the W5 machine to break out tough material. It also shields the holder from direct abrasive flow – a simple shape that adds real hours to your drum hardware.
4. 44 mm outer‑diameter wear washer – protect the holder, promote rotation
This is one of the most underappreciated components. LongTrust equips every W5‑G/20A² tooth with a wear‑resistant washer having an outer diameter of 4.4 cm (44 mm). It accomplishes two things at once: it shields the block face from erosion, and it reduces friction so the tooth rotates freely. Free rotation keeps the carbide tip evenly worn, and an evenly worn tip stays sharper for longer.
5. Self‑centering washer action reduces bore wear
By precisely centering the tooth in the holder bore, the washer minimizes wobble. Less wobble means less ovality developing in the bore over time, which translates into more stable seating and longer holder life.
6. Thick‑wall cylindrical clamping sleeve
The clamping sleeve holds the tooth securely throughout its entire service life. We use a heavy‑gauge sleeve that resists fatigue loosening, even under the high‑frequency hammering loads typical of tunneling and surface mining. Consistent clamping force equals consistent cutting – and zero lost teeth in the mat.
When you put all these details together, you get a milling tooth that simply wears down slower, rotates better, and protects the expensive components around it.
