Indexable drill U781TM — Ø21 mm, 105 mm cutting length

A robust U781TM indexable drill designed for precise, deep-hole machining in production environments and general workshop use

• High-stability 25 mm shank
• 105 mm cutting length for deep holes
• Compatible with Korloy WCm-0402 inserts
• Balanced Ø21 mm body for reliable feeds

Consistent hole quality and higher machining efficiency

The tool body delivers a rigid drilling platform that reduces vibration and runout, directly improving dimensional repeatability and surface finish. With a Ø21 mm diameter and 105 mm cutting length, this solution enables deeper holemaking without compromising stability. The 25 mm shank contributes to firm clamping in standard toolholders, which reduces micro-movements during interrupted cuts; the result is fewer rework cycles and a measurable improvement in cycle-time efficiency on serial operations. Technical features are translated into operational gains: tighter tolerances and less scrap, supporting a leaner production flow.

Rapid tooling change and proven insert compatibility

Designed to accept inserts from a major manufacturer, the drill body fits Korloy indexable plates of type WCm-0402, simplifying inventory and set-up. Using a standardised insert format shortens changeover time and lowers tooling costs by allowing re-use of bodies across multiple insert types where applicable. The modular approach makes maintenance straightforward: worn inserts are replaced rather than the entire tool, which reduces overall tooling expenditure and keeps spindle downtime to a minimum. The compatibility also streamlines procurement and ensures that replacement inserts are widely available for continuous operation.

Workshop robustness, handling and maintenance advantages

Constructed for everyday use in industrial environments, the tool balances cutting performance with serviceability. With an overall length of 184 mm and a body weight of 0.451 kg, handling on the bench and during tool changes is practical while maintaining the mass required for damping. The 56 mm shank engagement length secures axial stability in holders rated for 25 mm shanks. Routine checks for insert seating and clamping torque suffice to preserve accuracy; the modular design avoids complex regrinding and keeps maintenance cycles short. This combination of features supports reliable throughput and predictable tooling life in mixed-production settings.

FAQ

Which insert type fits this drill?
The drill accepts WCm-0402 indexable inserts; the body is specified to match Korloy plate geometry for secure seating and repeatable performance.

What is the usable cutting length?
The tool provides a cutting length of 105 mm, enabling deeper holemaking while maintaining stability for serial production tasks.

What shank size is required for clamping?
A 25 mm shank diameter with a 56 mm engagement length ensures secure clamping in compatible holders and supports rigidity during heavy-duty cuts.

Is the drill suitable for workshop and production environments?
Yes; the indexable-body design and balanced Ø21 mm diameter make the tool well suited to both workshop and industrial production, offering ease of maintenance and predictable tool life.

How does the U781TM reduce tooling costs?
By using replaceable WCm-0402 inserts, the U781TM limits expenditure to consumable plates rather than full-body replacements, shortening downtimes and lowering long-term tooling spend.
