147mm Morse Taper MT3 Taper Shank With B22 Drill Chuck Mount, Hardened And Ground - TECWERK

Benefit from the secure fit of an MT3 taper combined with the B22 drill‑chuck interface and the durability of a fully hardened and ground finish; this combination reduces runout and supports consistent tool performance. Improve machine uptime and minimise rework by specifying the DIN‑conforming arbor. Order the taper arbor directly via Metav Werkzeuge or request technical advice from our consultants.

Taper arbor MT3×B22 (TECWERK) — DIN 238, hardened and ground, 147 mm

Taper arbor MT3×B22 for accepting drill chucks; designed for drill and turning machines with a DIN 238 drill‑chuck interface

• DIN 238 drill‑chuck taper B22
• Morse taper MT3 external shank
• Fully hardened and precision ground
• Suitable for drill and turning machines

Proven precision for reduced runout and consistent results

A defined taper fit is the basis for rotational accuracy in machining. The MT3 external taper paired with the B22 drill‑chuck interface manufactured to DIN 238 provides a standardised seating that minimises micro‑movement. The hardened and ground finish lowers friction and limits elastic deformation during clamping, which in turn reduces runout and improves repeatability. These characteristics translate into fewer rejected parts and more predictable machining outcomes, particularly important for repetitive drilling operations and fine finishing tasks.

Durable design that lowers maintenance needs

Workshop applications demand components that resist wear and retain concentricity under repeated use. The arbor’s fully hardened and precision ground execution increases abrasion resistance and helps maintain retention force over prolonged service. Reduced wear means longer intervals between checks and regrinding, supporting continuous production schedules. In practical terms, the robust surface treatment protects both the arbor and the mounted drill chuck, contributing to lower total cost of ownership in a busy tooling environment.

Compact dimensions for straightforward machine integration

The Taper arbor MT3×B22 has an overall length of 147 mm, a form factor that suits a wide range of drill presses and turning centres while keeping overhang and imbalance low. Supplied as a single unit (packaging unit: 1), the arbor accepts Jacobs‑style chucks with the B22 taper and simplifies inventory management. The product is listed under SKU 2000832337NW for straightforward ordering and specification checks. For machine matching and balance considerations, consult technical notes to ensure optimal mounting and safe operation.

FAQ

Is the arbor compatible with standard MT3 spindles?
Yes. The arbor features an MT3 external taper designed for standard MT3 spindles and mates with B22 drill‑chuck fittings according to DIN 238.

What does compliance with DIN 238 mean for the user?
DIN 238 specifies the dimensions and tolerances for drill‑chuck tapers; conformity ensures interchangeability and predictable seating when using any B22‑compatible chucks with this arbor.

How does the hardened and ground finish affect performance?
The hardened and ground surface improves wear resistance and maintains concentricity, so the arbor preserves retention and reduces runout over many clamp cycles.

Which machines is this arbor suitable for?
The component is intended for drill presses and turning machines that accept MT3 external tapers and B22 drill‑chuck fittings; it is commonly used where Jacobs‑type chucks are mounted.

What is the overall length and how is it supplied?
Overall length is 147 mm and the item is supplied as a single unit (packaging unit: 1), referenced under SKU 2000832337NW.
