Robust drilling performance with a Ø55 mm cutting diameter and a secure 40 mm shank delivers reliable hole quality and process stability; the indexable concept using WCM-0804 inserts keeps downtime low. Order the U211TM directly via Metav Werkzeuge or ask our consultants for application advice.

U211TM — Indexable insert drill, Ø55 mm, for WCM-0804 inserts (Teknik Makina)

The U211TM is an indexable drill body designed for stable, high-precision holemaking in CNC machining where replaceable Korloy WCM-0804 inserts are preferred.

• Ø55 mm nominal diameter
• Compatible with Korloy WCM-0804 inserts
• 165 mm effective cutting length
• 40 mm robust shank diameter

Reliable hole quality and process stability

The design focuses on repeatable results in series production: a Ø55 mm nominal diameter combined with a 165 mm cutting length provides consistent engagement, while the mass and geometry of the tool body reduce vibration during cutting. This stability translates into fewer scrap parts and steadier cycle times, making the tool suitable where hole tolerance and surface finish matter. The indexable concept means only the cutting edges need attention, not the whole tool, which preserves machine uptime and supports tighter process control.

Economical machining with indexable inserts

Using WCM-0804 indexable inserts from Korloy enables quick edge changes and predictable machining costs. The insert-based approach separates cutting-edge wear from the tool body, so maintenance is limited to exchanging inserts and checking clamp integrity. Where cutting conditions vary, the system allows rapid adaptation by selecting insert grades or geometries without replacing the drill body, supporting cost-efficiency and operational flexibility in production environments.

Rigidity, clamping and dimensional data for stable setup

A 40 mm shank diameter and 68 mm shank length ensure secure clamping in standard toolholders, while the 280 mm overall length gives sufficient reach for many workpiece geometries. The tool’s 3.237 kg mass contributes to dampening of minor tool deflection under load, improving concentricity and hole roundness. These dimensional characteristics support robust setups on machining centres and reduce the risk of chatter when combined with appropriate holder and spindle rigidity.

Practical setup pointers and lifecycle considerations

For best results, match the holder and spindle clamping to the 40 mm shank and verify runout before production runs. Insert seating and torque of the clamping screws should be checked at regular intervals to maintain consistent cutting conditions. The modular nature of the design simplifies refurbishment: worn inserts are replaced quickly and the body inspected for damage, which helps extend overall tool service life and keeps the cutting process predictable.

FAQ

What insert type does this drill use?
The drill accepts Korloy WCM-0804 indexable inserts; the U211TM is configured for that insert geometry.

What are the key dimensions to check for holder compatibility?
Verify the 40 mm shank diameter and 68 mm shank length to ensure correct clamping in the selected toolholder for the U211TM.

Is the U211TM suitable for long-reach drilling?
With an overall length of 280 mm, the tool provides moderate reach; stability depends on holder and spindle rigidity as well as clamping practice.

How does the indexable design affect maintenance?
The indexable design reduces downtime by allowing quick replacement of worn WCM-0804 inserts rather than replacing the entire tool body, simplifying maintenance cycles for the U211TM.
