Indexable Insert Drill U108TM – Ø 20 mm, 119 mm overall length (Teknik Makina)

The Indexable Insert Drill U108TM is an indexable insert drill body engineered for reliable through-hole operations in production and workshop environments, compatible with WCM‑0402 inserts for efficient insert changeover

• 20 mm cutting diameter for standard holes
• Compatible with Korloy WCM-0402 inserts
• 40 mm effective cutting length
• 25 mm shank diameter for secure clamping

Faster, repeatable holemaking through optimised geometry

The U108TM drill body offers a combination of a compact design and a clear specification set to keep cycle times predictable. With a Ø 20 mm cutting diameter and a 40 mm cutting length, the tool supports repeated holemaking with consistent results, reducing scrap and rework. The 119 mm overall length balances reach and rigidity, helping to maintain concentricity and minimise runout when mounted in appropriate holders. Explaining the benefit: a defined effective cutting length means bosses and fixtures can be designed around a known cutting zone, simplifying process planning and reducing set-up variations for series production.

Economical tooling through insert compatibility and quick serviceability

Compatibility with WCM-0402 insert geometry allows rapid edge changes without replacing the whole tool body, converting maintenance time into productive machining minutes. Using standardised indexable inserts from trusted suppliers such as Korloy reduces per‑hole tooling costs and simplifies stock management for workshop stores. The modular approach also enables the selection of grades and coatings to suit specific workpiece materials, offering a pragmatic cost-benefit: lower running costs per hole and shorter downtime for insert replacement compared with solid carbide alternatives.

Secure clamping and machine-friendly interface for stable machining

A 25 mm shank provides a solid interface for chucks and collet systems, improving stability under load and helping to avoid chatter. The robust shank dimension supports secure clamping and a consistent connection to the spindle, which contributes to reduced vibration and extended insert life. For machine operators, this translates into fewer corrective interventions and a steadier process window, particularly important when running medium-length production cycles where tool stability directly affects surface finish and positional tolerance.

Practical applications and shop-floor benefits

Designed as a general-purpose indexable drilling solution, the tool body is suited to workshops that prioritise serviceability and predictable output. The construction supports repeated insert changes and simplifies inventory: keep a small selection of WCM-0402 inserts and one tool body per diameter to cover many jobs. The relatively low mass of the assembly aids acceleration and deceleration on CNC machines, making the system suitable for both single‑station machining centres and multi‑spindle production cells where tooling change speed and reliability are critical.

FAQ

What insert type fits this drilling body?
The drilling body accepts WCM-0402 indexable inserts; Korloy inserts with this designation are compatible with the U108TM.

Which shank size is required for correct clamping?
A 25 mm shank diameter is specified for the U108TM to ensure secure clamping and machine compatibility.

What is the effective cutting length of the tool?
The tool provides a 40 mm cutting length, enabling controlled hole depth and repeatable machining.

Is the tool suitable for long-reach drilling applications?
With a 119 mm overall length, the tool offers modest reach while maintaining rigidity; it is optimised for standard through-hole and medium-reach operations rather than extreme long-reach scenarios.

How does indexable insert tooling reduce running costs?
By replacing only the worn inserts (WCM-0402) rather than the entire body, the system lowers per-hole tooling expense and shortens maintenance downtime.
