SW7 Asphalt Milling Picks – 41g Carbide Tip
The ALSKAR SW7 Asphalt Milling Picks are tungsten carbide-tipped road milling tools designed for asphalt pavement removal and surface milling with compatible large cold milling machines.
Featuring a 41g cap-shaped carbide tip, 88mm overall length, 48mm reference length, and 20mm round shank, the SW7 series is intended for demanding asphalt milling applications using professional road milling equipment.
Available in With Groove (SW7-G/20) and Without Groove (SW7/20) configurations, both models share the same carbide tip specifications and primary dimensions.

1. SW7 Carbide Asphalt Milling Picks
The ALSKAR SW7 Series is designed for asphalt pavement milling, road rehabilitation, and surface removal applications using compatible large cold milling machines.
Each milling pick features a 41g tungsten carbide cutting tip supported by a steel pick body and a 20mm round shank.
According to ALSKAR’s product drawings, the SW7 Series has an 88mm overall length, a 48mm reference length, a nominal carbide tip base diameter of 21mm, and an upper tip diameter of 11mm.
The series is available in two configurations: SW7-G/20 with an extractor groove and SW7/20 without an extractor groove.
Both configurations share the same carbide tip specifications and primary dimensions, allowing customers to select the appropriate pick head design based on their existing cutting tools and maintenance requirements.
The SW7 series is an important cutting tool option for professional road milling contractors, equipment maintenance providers, and industrial distributors.
2. 41g Cap-Shaped Tungsten Carbide Cutting Tip
The SW7 Series features a 41g cap-shaped tungsten carbide cutting tip designed for asphalt pavement milling.
Tungsten carbide is widely used in road milling cutting tools because of its hardness and resistance to abrasive wear.
The carbide tip forms the primary cutting interface with asphalt pavement, while the supporting steel body transfers cutting forces through the tool holder assembly.
According to ALSKAR’s product drawings, the carbide tip has a nominal base diameter of 21mm and an upper diameter of 11mm.
The 41g carbide tip provides a larger cutting tip configuration than the lighter SW4, SW5, and SW6 models in the ALSKAR asphalt milling pick range.
Actual cutting performance, wear characteristics, and service life depend on pavement composition, abrasiveness, cutting depth, machine settings, pick rotation, and operating conditions.
3. Two Pick Head Configurations
The ALSKAR SW7 Series is offered in two configurations to accommodate different milling tool designs and maintenance requirements.
SW7-G/20 – With Groove
The SW7-G/20 features an extractor groove in the steel pick head.
The groove provides an access point for suitable extraction tools, helping operators remove worn milling picks during routine maintenance and replacement.
SW7/20 – Without Groove
The SW7/20 features a smooth steel pick head without an extractor groove.
This configuration maintains the same carbide tip geometry, shank diameter, overall length, and primary dimensions as the grooved model.
Shared Technical Specifications
- 41g Tungsten Carbide Tip
- 88mm Overall Length
- 48mm Reference Length
- 20mm Round Shank Diameter
- Nominal 21mm Carbide Tip Base Diameter
- Nominal 11mm Upper Tip Diameter
Customers should select the appropriate configuration according to their existing milling pick design, tool holder system, and maintenance requirements.
4. 20mm Round Shank Construction
Both SW7 milling pick configurations feature a 20mm round shank designed for installation in compatible road milling tool holders.
The 88mm overall length and 48mm reference length provide defined dimensions for comparing replacement cutting tools.
The round-shank configuration is intended for use with suitable tool holder assemblies and retaining systems.
Correct installation depends on matching the shank dimensions, head geometry, retaining components, and tool holder requirements.
A matching 20mm shank diameter alone does not guarantee universal compatibility with all milling machines or tool holders.
5. Designed for Asphalt Milling Applications
The ALSKAR SW7 Series is intended for asphalt pavement milling, surface removal, and road rehabilitation applications.
Recommended Applications
- Asphalt pavement milling

6. For Large Cold Milling Machines
The ALSKAR SW7 Asphalt Milling Picks are intended for demanding asphalt milling applications using compatible large cold milling machines.
The series features a 41g carbide tip, a 20mm round shank, and a defined cutting head geometry suitable for matching road milling tool holder systems.
Both grooved and non-grooved configurations are available to meet different replacement cutting tool requirements.
The SW7 Series provides an additional carbide tip size option for customers operating larger milling equipment or selecting tools for more demanding cutting conditions.
Machine compatibility must be verified by comparing the existing cutting pick dimensions, tool holder geometry, retaining system, and machine requirements before installation.
