MT3–B18 taper arbor — hardened and ground with DIN 238 drill‑chuck taper (TECWERK)

The MT3–B18 taper arbor is a hardened, ground arbor designed to accept drill chucks on drilling and turning machines, offering a precision interface for reliable toolholding.

• DIN 238 drill-chuck taper
• Hardened and ground finish
• MT3 shank with B18 reception

Secure, low‑runout mounting for accurate machining

The design provides a Morse taper (MT3) interface mated to a B18 reception, giving a rigid and concentric connection between machine spindle and chuck. A correctly fitted taper arbor reduces runout and vibration, which directly improves hole quality and tool life. For users unfamiliar with the term, runout describes the deviation of the rotating axis from true centre; minimising it prevents uneven wear and poor surface finish. The hardened, ground surfaces ensure a repeatable, tight fit that aids in maintaining precision across repeated mounting cycles.

Broad compatibility with standard drill chucks and machines

Compliance with DIN 238 means the taper conforms to the recognised drill‑chuck standard, simplifying selection and ensuring compatibility with commonly used chucks. The arbor’s MT3 shank is suitable for machines accepting Morse taper shanks and, via the B18 reception, accepts Jacobs‑style drill chucks for a secure union. This combination offers practical flexibility in workshops that use both drill presses and toolroom lathes, enabling straightforward interchange of chucks without modification. The clear standardisation reduces downtime and supports predictable tool setup.

Built to last: hardened and ground for dependable workshop use

Manufactured with a focus on durability, the arbor is hardened and ground to resist wear and maintain concentricity over time. This robust construction reduces the need for frequent replacement and supports steady production schedules. In routine use, simple cleaning and correct withdrawal methods will preserve the taper condition; light lubrication of the contact faces during storage avoids corrosion without impairing the fit. The result is a component that contributes to lower maintenance needs and dependable everyday performance on the shopfloor.
