Frequently asked
What is the maximum clamping capacity?
The chuck accommodates tools ranging from 1 mm to approximately 16 mm.
Which draw bolt threads are supported?
Standard options include M12x1.5P and M12x1.75P depending on the model.
How is the arbor hardened?
It is case-hardened to achieve a surface hardness of 55–58 HRC.
More questions buyers ask
What is a drill chuck arbor?
A drill chuck arbor is a precision tool holder that connects a drill chuck to the spindle of a machine tool like a drill press or milling machine.
What does MT2, MT3, or MT4 mean?
These refer to Morse Taper sizes, which are standard conical interfaces used to secure tools in machine spindles.
What is the accuracy of these arbors?
These arbors are engineered with a runout accuracy of ≤ 0.01 mm for high-precision drilling.
What material are these arbors made of?
They are manufactured from high-carbon or hardened steel and case-hardened to 55–58 HRC for durability.
Are these arbors compatible with all drill chucks?
They are compatible with specific tapers like JT6 or B16. Please check your chuck's taper specification before purchasing.
Can these be used for milling?
Yes, they are suitable for light milling and precision drilling tasks in industrial workshops.
Do you provide a warranty?
Pentagon Machines and Tools provides standard industrial warranties on all machine accessories.
How do I choose the right arbor?
Match the shank type (e.g., MT2, R8) to your machine spindle and the taper type (e.g., JT6, B16) to your drill chuck.
Is pan-India delivery available?
Yes, we offer reliable pan-India shipping for all our industrial machine tools and accessories.
Do you provide GST invoices?
Yes, all purchases include a valid GST invoice for business accounting.
Who should choose the MT2-JT6 arbor?
Ideal for users with standard benchtop drill presses or small milling machines requiring a reliable MT2 interface.
Who should choose the R8-JT6 arbor?
Best for professional machinists using R8 spindle milling machines who need high stability for precision drilling.
Who should choose the ISO30/40-JT6 arbor?
Recommended for CNC operators requiring high-speed performance and minimal vibration in automated machining setups.
How does MT2 compare to MT4?
MT2 is for smaller, lighter-duty machines, while MT4 is designed for larger, heavy-duty drilling equipment with higher torque requirements.
Is JT6 better than B16?
Both are standard tapers; the choice depends entirely on the specific drill chuck you are using. They are not interchangeable.
