The 1011565 / 1691412 milling drum base holder is a weld-on foundation component engineered for road milling machine drums. Manufactured by JESTIN from forged alloy steel with heat treatment, this base holder provides a precision-machined mounting surface for tool holders on cold planer drums. It is specified for QC100, QC110HD, and RM400 milling machines, with cross-compatibility for Wirtgen, CAT, XCMG, and SANY road milling equipment. The base holder distributes cutting forces across the drum surface, reducing localized stress during asphalt and concrete pavement removal. Each unit carries a 1-year warranty, supporting fleet operators and commercial users in managing maintenance schedules and minimizing machine downtime on highway milling and pavement recycling projects.
The base holder is forged from alloy steel and subjected to heat treatment, producing a component with controlled hardness and impact resistance suited to road milling environments. The forging process aligns the material grain structure, while heat treatment establishes a balance between surface hardness and core toughness. This construction method supports the base holder in withstanding repeated cutting loads during pavement removal and recycling operations, where the drum encounters varying asphalt densities and embedded aggregate.
The mounting face of each base holder is machined to tight tolerances, ensuring that tool holders seat squarely and consistently on the drum. Proper alignment between the base holder and tool holder contributes to accurate pick positioning, which affects milling pattern uniformity and pick wear rates. The machined surface also facilitates straightforward tool holder replacement during drum maintenance, allowing technicians to swap holders without reworking the drum surface.
The base holder attaches to the milling drum by welding, creating a permanent bond that transfers cutting forces directly into the drum body. The weld-on configuration is the standard mounting method for road milling drum tooling systems and is compatible with OEM drum welding procedures. During installation, base holders are positioned according to the drum's spiral tool layout and welded in place using approved filler metals. Weld joints should be inspected for cracks during routine drum maintenance to identify fatigue before it leads to holder separation.
The 1011565 / 1691412 base holder is specified for QC100, QC110HD, and RM400 road milling machines. It also serves as a replacement component on Wirtgen, CAT, XCMG, and SANY cold planer models that use equivalent drum tooling systems. When performing drum tooling maintenance, the base holder is typically replaced alongside tool holders (part number 187002 / C10LG-D-20), milling picks (W6/20A² / 2800874), retaining pins, spacers, and wear rings. Sourcing these components from the same supplier helps ensure consistent fit and reduces the risk of mismatched wear parts on the same drum, which can cause uneven cutting and accelerated drum wear.

Complete road milling drum service typically involves several wear components beyond the base holder. Tool holders (187002 / C10LG-D-20) mount directly onto the base holder and secure the milling picks in position. Milling picks (W6/20A² / 2800874) are the cutting teeth that contact the pavement and require regular rotation or replacement based on mileage and asphalt hardness. Retaining pins secure picks within the tool holder, while spacers and wear rings manage clearance and protect mounting surfaces from abrasive damage. Inspecting all these components during each drum service interval helps identify wear before it leads to drum damage or unexpected downtime, and purchasing them as a matched set simplifies inventory management for enterprise customers.
The 1011565 / 1691412 base holder fits QC100, QC110HD, and RM400 road milling machines, and is compatible with equivalent drum tooling systems on Wirtgen, CAT, XCMG, and SANY cold planers. Buyers should verify their machine's drum tooling specification before ordering.
The base holder is welded directly to the milling drum surface. It is positioned according to the drum's spiral tool layout and secured using approved welding procedures and filler metals. Weld joints should be inspected during routine maintenance.
The base holder is manufactured from forged alloy steel with heat treatment, providing a balance of hardness, impact resistance, and weldability for road milling applications.
JESTIN provides a 1-year warranty for the 1011565 / 1691412 milling drum base holder, covering manufacturing defects under normal operating conditions.
During drum tooling maintenance, the base holder is typically serviced alongside tool holders (187002 / C10LG-D-20), milling picks (W6/20A² / 2800874), retaining pins, spacers, and wear rings to ensure a complete and matched tooling system.
