U728TM Indexable Insert Drill — Ø28 mm, 112 mm cutting length (Teknik Makina)

The U728TM indexable insert drill for metalworking centres and production drilling, designed for long cutting engagement and reliable insert replacement.

• 28 mm cutting diameter
• 112 mm cutting length
• 25 mm shank diameter
• Compatible with SPMG 0904 inserts

Consistent machining performance with defined cutting geometry

The U728TM is built to deliver repeatable hole quality across series production by combining a long cutting engagement with a solid, machined body. The 112 mm cutting length gives extended reach for deep-hole applications while the Ø28 mm diameter maintains concentricity and roundness under load. Engineers benefit from predictable tool life and stable cutting forces, which reduces process variation and the need for costly rework. The robust construction also supports reliable clamping in standard toolholders, enabling steady chip evacuation and improved surface finish.

Faster tool changes and lower process costs through standard inserts

Compatibility with SPMG 0904 indexable inserts from established vendors (notably Taegutec and YG-1) simplifies logistics and lowers inventory overhead. Using widely available inserts means quick replacement and minimal machine downtime; worn cutting edges are swapped rather than replacing the entire tool body. This standardisation helps to calculate cost-per-hole precisely and demonstrates a clear cost-benefit advantage for batch production. The insert interface is designed for secure seating, ensuring repeatable positioning and consistent cutting geometry after every change.

Stable clamping and balanced design for vibration control

A 25 mm shank diameter combined with a 56 mm shank length and an overall length of 196 mm provides secure toolholding and improved torsional rigidity. The moderate mass (approx. 0.642 kg) contributes to a balanced assembly that resists chatter during plunge and peck drilling cycles. These mechanical properties translate into better hole tolerances and longer insert life, particularly when machining steels and alloys where tool deflection would otherwise compromise form and finish. The design supports standard mounting systems, making integration into existing tool inventories straightforward.

Workflow reliability supported by Metav’s supply and expertise

Selecting a tool is part of a wider production decision. Metav’s distribution philosophy focuses on accessible precision: a European supply hub in Emmerich acts as a quality filter, and a broad catalogue reduces the number of suppliers required. With a track record of over 48,000 customers and more than 250,000 products, Metav provides continuity of supply and technical advice that helps plan tool replacement cycles and spares stocking. For procurement and process engineers this means reliable deliveries and transparent handling from order to workshop.
