More questions buyers ask
What is a Drill Chuck Arbor?
A drill chuck arbor is a precision tool holder component that connects a drill chuck to a machine spindle, such as a lathe or milling machine.
What does MT2-JT6 mean?
MT2 refers to the Morse Taper 2 shank size, and JT6 refers to the Jacobs Taper 6 connection for the drill chuck.
What is the runout accuracy of these arbors?
Pentagon drill chuck arbors typically offer a high runout accuracy of ≤ 0.01 mm for precision machining.
What materials are used for these arbors?
They are manufactured from high-carbon or hardened steel, often case-hardened to 55–58 HRC for superior durability.
Can these arbors be used on milling machines?
Yes, depending on the shank type (e.g., R8, ISO30, ISO40), they are widely used on various milling machines and drill presses.
How do I choose the right arbor for my machine?
Identify your machine spindle taper (e.g., MT2, R8, ISO30) and your drill chuck taper (e.g., JT6) to ensure compatibility.
Are these arbors suitable for industrial use?
Yes, they are designed for industrial environments, including automotive, aerospace, and general manufacturing sectors.
What is the clamping range for these arbors?
These arbors support drill chucks typically accommodating tools from 1 mm to 16 mm.
