More questions buyers ask
What is a milling machine drawbar rod?
A drawbar rod is a critical machine component used to secure cutting tools or collets into the milling machine spindle, ensuring stability during operation.
What material is the Pentagon drawbar made of?
It is manufactured from high-grade hardened alloy steel with a tensile strength of 850Mpa for maximum durability.
What is the function of the drawbar in a milling machine?
The drawbar pulls the tool holder or collet into the spindle taper, providing the necessary clamping force for secure and precise machining.
Are these drawbars compatible with all milling machines?
They are designed for standard R8, ISO30, and ISO40 spindles. Please check your machine's spindle type and thread pitch before purchasing.
What head types are available?
Pentagon drawbars are available with either Hex Head or T-handle designs for ergonomic and efficient tool changes.
How do I choose the right drawbar for my machine?
Select based on your spindle taper (R8, ISO30, or ISO40) and the specific thread pitch required by your machine's drawbar assembly.
What is the hardness rating of these rods?
These rods feature a hardness range of HRC 35 – 45, providing excellent resistance to wear and deformation.
Can these drawbars withstand high temperatures?
Yes, they are engineered to maintain performance and structural integrity at temperatures up to 250°C.
Do you provide a warranty with these products?
Yes, Pentagon products come with standard manufacturer warranty support. Contact our team for specific terms.
Is GST invoice available for this purchase?
Yes, all purchases include a valid GST invoice for your accounting and tax compliance needs.
Who should choose the R8 spindle drawbar?
Ideal for operators using standard turret milling machines requiring a reliable M12x1.5P thread connection.
Who should choose the ISO30/NT30 spindle drawbar?
Best for workshops utilizing ISO30/NT30 spindle interfaces that require a robust M12x1.75P thread setup.
Who should choose the ISO40/NT40 spindle drawbar?
Recommended for heavy-duty milling applications using ISO40/NT40 spindles with M16x2.0P thread requirements.
How does the R8 drawbar compare to the ISO30 version?
The R8 version is designed for smaller turret mills with M12x1.5P threads, whereas the ISO30 version is for larger spindles with M12x1.75P threads.
Is the ISO40 drawbar stronger than the R8 version?
The ISO40 drawbar is designed for higher-load applications with a larger M16 thread, offering superior clamping force for heavy-duty machining.
