Precision alloy carbide construction

Manufactured from precision-alloy steel with brazed carbide tips, W6/20 and W7/20x2 picks deliver durable, consistent high-performance cutting under strict quality control.

Optimized cutting edge geometry

Sharpened, engineered carbide geometry yields sharp, long-lasting edges for high-efficiency material removal and superior surface finish.

Heat treated reinforced shanks

Heat treated, reinforced shanks provide exceptional impact resistance and secure retention during heavy-duty milling, reducing downtime and maintenance.

Secure precision mounting compatibility

Precision mounting and broad compatibility with standard milling cutters enable fast installation, uniform removal, faster cycle times, and lower life-cycle costs.

Durable Precision Road Picks

The W6/20 and W7/20x2 road milling picks feature high-hardness tungsten carbide tips bonded to stainless steel bodies (about 0.3 kg) and are engineered for milling drums on road rollers, asphalt pavers and cold planers for asphalt, asphalt-concrete, concrete, railway and tunnel surface work. A wear-resistant coating and impact-resistant design deliver high cutting efficiency for fine and rough milling, concrete cutting and surface roughening while extending service life and reducing downtime and replacement frequency. The secure carbide-to-steel construction, optimized tip geometry and corrosion-resistant finish ensure stable rotation and resistance to loosening, with OEM customization available and quality assured by ISO9001 and SGS certifications.

Municipal Street Maintenance Milling

City maintenance crews use W6/20 and W7/20x2 teeth for routine street resurfacing, pothole removal, and targeted profile repairs on local roads. Durable carbide tips and secure attachment reduce downtime and the need for frequent replacements, keeping maintenance cycles efficient.

Airport Runway Pavement Preparation

W6/20 and W7/20x2 cutters precisely mill asphalt and concrete to the exact profiles required for runway resurfacing and safety upgrades. Consistent material removal and long-lasting carbide tips support intensive milling schedules with minimal tool wear.

Large Scale Roadbed Correction

In major road construction and rehabilitation projects these picks remove pavement layers and correct roadbed profiles across wide areas to meet design tolerances. Their heavy-duty construction and carbide tips deliver the durability and efficiency needed for prolonged, high-production milling operations.

Material Introduction

These road milling picks feature a tungsten carbide cutting tip securely bonded to a stainless steel body, combining extreme hardness for efficient cutting with a resilient shank for impact resistance. A wear-resistant coating and robust material pairing help resist abrasion and loosening under heavy asphalt and concrete milling, extending service life and reducing replacement frequency. Manufactured under ISO9001 and SGS-recognized processes, the carbide-stainless configuration is optimized for road planing, fine milling and tunnel or railway cutting applications.

FAQ

What machines and application scenarios are W6/20 and W7/20x2 road milling picks designed for?

These picks are spare cutting tools for road milling and planing equipment—typical machines include cold planers, asphalt milling machines, trenchers and small-to-medium road recyclers. They are used for asphalt and concrete surface removal, profile milling, pothole repair, shoulder and joint cleaning, and preparing a road base for repaving.

How do I check compatibility with my milling machine and correctly install these picks?

Verify the shank diameter and overall length of the pick against your machine’s tool holder and the part numbers (W6/20, W7/20x2). Confirm the required locking sleeve/retaining pin type and orientation from your machine manual. Before installation, clean the holder, inspect for wear or damage, insert the pick fully, engage the locking device and torque/secure per the machine maker’s instructions. Never substitute a different shank size without the correct adapter.

What are these milling teeth made of and how do they perform on different surfacing materials?

These picks typically have a carbide cutting tip brazed or welded to a hardened steel shank. Carbide tips give excellent abrasion resistance for asphalt and good cutting ability in concrete or recycled base material. Different grades and tip shapes perform better on softer asphalt (faster cutting) versus hard, abrasive concrete (slower cutting but longer life). The W7/20x2 geometry is commonly chosen for higher material removal rates or specific profile work—pick the grade and shape based on your surface type.

What operating practices maximize cutting performance and tool life?

Use machine-recommended spindle speed, feed rate and cut depth—avoiding overly aggressive depth or feed that causes impact and premature breakage. Keep picks evenly loaded by planning passes and rotating or staging replacements to promote uniform wear. Inspect holders and replace worn or loose sleeves. Remove debris from holders and use dust control/cooling methods if advised by the machine maker. Proper selection of tip grade for the material being milled also extends life.

How do I know when a road milling pick needs replacement?

Replace picks when you notice rounded or mushroomed carbide, chipped or missing tips, significantly reduced cutting rate, increased fuel use or vibration, or when the tip diameter is below the manufacturer’s minimum-specified size. Also replace immediately if the shank is bent, cracked or the weld/braze has failed—continuing to run damaged picks risks machine damage and safety hazards.

What safety and handling precautions should I follow when using and storing these picks?

Always lock out and isolate the machine before inspecting or changing picks. Wear appropriate PPE (gloves, eye protection, hearing protection and respiratory protection if dust is present). Use the correct removal/installation tools—do not hammer picks in loosely. Store picks in a dry, organized manner to protect carbide tips and prevent accidental injury. Dispose of badly worn or fractured picks safely according to local rules.
