The 1012345 tool holder, model C10LG-D-20, is a weld-on pick holder designed for mounting on road milling machine drums. It secures carbide-tipped milling picks during asphalt and concrete cutting operations. This product serves as a direct replacement for original equipment holders on multiple mainstream road milling machine brands, and supports regular drum tooling maintenance for commercial users in road construction and infrastructure sectors. It works in coordination with C10LG series milling picks, retaining pins, spacers, and wear rings to form a complete cutting tool assembly.
This tool holder adopts a retaining pin locking system to fix C10LG series milling picks. The structure allows for quick pick replacement during on-site maintenance, while keeping the cutting tool in a stable position during operation. Stable pick positioning supports consistent cutting depth and angle during milling work, which contributes to steady material removal efficiency in continuous construction schedules. The holder is a core component of the milling drum tooling system, and its condition directly affects the operating status of milling picks.
This pick holder is designed for use in various road construction and maintenance works. Common application scenarios include highway surface milling, pavement recycling projects, rut removal on urban roads, and large-scale excavation operations on construction sites. It adapts to both asphalt and concrete pavement milling tasks, and matches the working parameters of mainstream mid-size and large road milling machines. For projects with long continuous working hours, regular inspection and replacement of tool holders helps maintain stable construction progress.
This C10LG-D-20 specification tool holder is compatible with road milling machines from Wirtgen, CAT, XCMG, SANY, and BOMAG that use the same holder specification. It is manufactured according to the installation dimensions of original equipment holders, and can be used as a direct replacement part during equipment maintenance. Before placing an order for commercial procurement, buyers can confirm the holder specification marked on their existing milling drum to ensure matching.
In complete milling drum maintenance work, this tool holder is usually replaced together with related wear parts. Matching components include C10LG series milling picks, retaining pins, spacers, and wear rings. Replacing all related wear parts at the same maintenance cycle helps ensure consistent fitting accuracy between components, and reduces the frequency of on-site adjustments. For industrial clients carrying out bulk drum refurbishment, supporting procurement of all related parts can simplify the procurement process and shorten maintenance downtime.
This tool holder is manufactured from forged alloy steel, and undergoes heat treatment after forming. The forging process forms a uniform internal grain structure in the material, and the heat treatment process adjusts the material hardness to adapt to impact loads during milling work. The material properties help the holder withstand repeated impacts from cutting operations under normal working conditions.
The pick mounting bore of the tool holder is processed with precision machining procedures. The machined bore ensures proper fitting between the holder and C10LG series milling picks, and maintains accurate tool alignment after installation. Proper alignment reduces abnormal wear on both the pick and the holder, and helps extend the service life of the entire cutting assembly.

This tool holder adopts a weld-on installation method, and is fixed to the milling drum by welding. During installation, the welding position should be adjusted according to the original drum layout to ensure consistent arrangement angle and spacing of all holders. It is recommended that the welding operation be carried out by personnel with relevant welding operation qualifications, to ensure welding strength and installation accuracy. After welding, the pick bore position should be checked to avoid deviation that affects pick installation.
During daily equipment inspection, the wear condition of the tool holder should be checked regularly. When wear on the pick bore causes a decrease in pick retention force, or when the holder body shows visible deformation or crack damage, the holder should be replaced in time. At the same time as replacing the tool holder, the welding position of the drum body should be inspected for damage. Timely replacement of worn holders helps avoid abnormal damage to milling picks caused by loose fixation.
This tool holder is designed according to C10LG-D-20 specification, and is compatible with standard C10LG series milling picks that match this specification. Buyers can confirm the pick model before procurement to ensure fitting consistency.
The tool holder is fixed to the milling drum by welding. To ensure welding strength and installation accuracy, it is recommended that the installation be completed by personnel with qualified welding operation experience. Improper welding may lead to holder displacement or falling off during operation.
The 1-year warranty covers manufacturing defects of the product under normal use conditions. Damage caused by improper installation, overloaded operation, or abnormal working conditions is not included in the warranty scope.
