PENTAGON Drawbar Tie Rod for Milling Machine Price in India — M12x1.5

A drawbar-tie rod is a critical component that runs through the spindle of a vertical milling machine. Its primary function is to securely clamp tool holders (like collets or end mill holders) into the spindle taper, ensuring they remain stable and rigid during high-load machining operations.

Our drawbar-tie rods are constructed from high-strength, heat-treated alloy steel to withstand high clamping forces and resist deformation, ensuring a long service life.

These drawbars are designed for vertical RAM turret milling machines and are compatible with standard ISO and NT spindle interfaces. Please check your machine's specifications and match the thread size (M12 or M16) and length before ordering.

The required thread size is determined by your milling machine's spindle. The M12 is common for smaller R8 spindles, while the M16 is often used in larger ISO/NT30/40 spindles. Consult your machine's manual for the correct specification.

The thread pitch must match your machine's existing drawbar. While both are M12, the 1.5mm pitch (coarse) and 1.75mm pitch (finer) are not interchangeable. Using the wrong pitch will damage the threads.

PENTAGON drawbar-tie rods come with a manufacturer's warranty against defects in material and workmanship. Please refer to our warranty policy for complete details.

Installation is a direct fit process. Simply thread the new drawbar into the tool holder from the top of the spindle head and tighten it to the manufacturer's recommended torque specification. Ensure threads are clean and lightly lubricated.

Proper clamping force is essential for machining accuracy and safety. It reduces spindle runout, minimizes vibration, improves surface finish, and extends the life of both your cutting tools and the machine's spindle bearings.

The M12x1.5 drawbar is ideal for users with smaller vertical turret mills, typically those with an R8 spindle taper that specifically requires a 12mm diameter coarse thread (1.5mm pitch). It is the most affordable option for standard milling applications.

This variant is for operators whose milling machines use an R8 or similar spindle but require a finer 1.75mm thread pitch. It's crucial to select this if your machine's manual or existing drawbar specifies M12x1.75 to prevent thread damage.

The M16x2 drawbar is designed for heavier-duty vertical milling machines, often those with larger ISO/NT 30 or 40 spindle tapers. Its larger diameter provides greater strength and rigidity, making it suitable for more demanding cutting operations and larger tooling.

The primary difference is the diameter and strength. The M16 drawbar is 4mm wider and significantly stronger than the M12 models, designed for larger machines and heavier workloads. The choice is not interchangeable and is dictated by your machine's spindle design.

Thread pitch does not directly impact performance but determines compatibility. You must match the pitch to your machine. A coarser pitch (like 2.0mm on the M16) allows for faster tightening, while a finer pitch (1.5mm) offers more precise tension control, but they are not cross-compatible.

For most standard toolroom milling machines (like a Bridgeport-style mill with an R8 spindle), the M12x1.5 is the most common and suitable choice. However, always verify your machine's specific requirements before purchasing.
