31.6mm Centre Drill Type 665 Full Tip 60° 160mm Overall Length MK4 - RÖHM

Take advantage of the proven combination of a 60° precision tip, a full solid point and a standard MT4 taper for reliable axial support and accurate alignment in routine turning operations; order directly via Metav Werkzeuge or consult the Metav team for application advice.

Centre Point Type 665 (MT4) — RÖHM fixed full-point, 60° tip

The Centre Point Type 665 (MT4) is a fixed centre designed to provide accurate axial support and repeatable alignment in machining applications, especially for turning and light drilling operations where a robust, full-point support is required.

• Solid centre point with full tip
• 60° precision tip angle
• MT4 Morse taper shank
• Hardened and ground tool steel

Accurate alignment for consistent concentricity

Designed as a workshop-grade centring solution, this fixed centre delivers precise axial locating with a 60° tip that matches standard lathe centres and tailstocks. The full point construction provides a continuous contact area under load, reducing point deflection and helping to maintain consistent concentricity during rotation. For production environments where repeatability matters, the combination of the tip geometry and the taper connection ensures minimal runout and clearer quality control of turned features.

Robust construction for reduced maintenance

Manufactured from tool steel and fully hardened and ground, the component resists wear and preserves its geometry under regular use. This hardening treatment prolongs the service life of the point, reducing the frequency of replacement and the associated downtime. The resilient design is particularly advantageous where axial loading or intermittent shock occurs during set-up and short production runs, enabling workshops to rely on the centre point as a durable locating element.

Simple integration with standard machines

The product uses a standard MT4 Morse taper shank, enabling straightforward mounting in compatible spindles, tailstocks and adaptor systems without special fittings. The taper provides secure retention and accurate axial positioning so the point can be transferred between machines with consistent performance. With a total length of 160 mm and a nominal diameter of 31.6 mm, the geometry is suited to common centre-holding setups while offering sufficient projection for a range of workpiece sizes.

Practical benefits at the workbench

Beyond technical performance, the component simplifies routine set-up and inspection tasks: the clear tip geometry makes contact points easy to visualise, and the solid construction reduces the risk of tip breakage during handling. For smaller shops and industrial lines alike, this results in faster set-ups and fewer interruptions. The product is offered as a single unit per package and carries the legacy of a recognised brand, which supports confidence in everyday workshop use.

FAQ

What machines are compatible with this centre point?
The centre point is designed for machines with an MT4 Morse taper socket; it fits standard tailstocks and spindles that accept an MT4 shank and provides stable axial support during turning.

How does the 60° tip affect performance?
A 60° tip offers the common geometry for lathe centres, ensuring predictable contact and alignment; the full-point design of the Type 665 spreads load and reduces localised wear.

Is the centre point suitable for heavy-duty turning?
The fully hardened and ground tool steel construction increases wear resistance, but the fixed full-point design is optimised for axial support and medium-duty operations rather than large-scale heavy cutting.

How should the point be maintained to preserve accuracy?
Keep the full point clean and free from chips or coolant residue; periodic visual inspection and gentle cleaning after use will help maintain tip geometry and concentric performance.

What is the exact designation for ordering?
Order the RÖHM Centre Point Type 665 (MT4) using article number 4121011131NW for accurate reference.
