Teknik Makina U159TM Insert Drill Body – 24.5 mm diameter, 25 mm shank

The U159TM insert drill body is an indexable drilling component for metalworking that accepts Korloy WCM‑0503 inserts and is designed for use in standard 25 mm toolholders

• 24.5 mm cutting diameter
• 25 mm shank for standard toolholders
• 72 mm effective cutting length
• Compatible with Korloy WCM‑0503 inserts

Modular indexable design for lower running costs

The insert-style construction delivers a modular approach to drilling that separates the cutting edge from the tool body. By using replaceable Korloy WCM‑0503 inserts, the tool reduces the need to replace an entire drill when the cutting edge wears, which lowers ongoing tooling expenditure and shortens machine downtime. The design supports quick insert changes and straightforward stock-keeping of spare parts, making it a practical choice for shops that balance production demands with cost control.

Secure clamping and improved rigidity with a 25 mm shank

A straight 25 mm shank provides compatibility with a wide range of standard toolholders and clamping systems. The combination of a robust shank and a well-dimensioned tool body contributes to stability during axial loading and helps maintain hole quality across series production. The tool’s mass (approx. 0.453 kg) offers a balanced feel in the spindle, aiding repeatable centring and vibration resistance without excessive inertia for most medium-duty operations.

Geometry and reach optimised for medium-depth holes

With a cutting diameter of 24.5 mm and an effective cutting length of 72 mm, the configuration is suited to medium-depth blind and through-hole work where consistent edge life and dimensional control are required. The total length of 154 mm allows the body to reach into assemblies while retaining sufficient overhang for effective chip formation. Explaining the terminology: the effective cutting length denotes the maximum continuous depth at which the cutting edges can engage the workpiece without extension or special adaptors.

Easy integration into CNC and conventional setups

The body is compatible with standard holders and with Korloy indexable inserts, easing integration into both CNC machining centres and manual machines that accept a 25 mm shank. The indexable format supports predictable maintenance intervals and simpler inventory management, while the neutral body geometry permits straightforward programme transfer between machines. For traceability and ordering, the item is listed under the SKU U159TM and is manufactured by Teknik Cutting Tools

FAQ

Which inserts fit this tool?
The drill body accepts Korloy WCM‑0503 indexable inserts; these inserts are specified for use with the Teknik Makina U159TM insert drill body

What shank size is required?
A 25 mm straight shank holder is required; the tool is designed for standard 25 mm toolholders and clamping systems

How deep can this tool drill?
The effective cutting length is 72 mm, while the total length is 154 mm, which indicates the practical reach for medium-depth operations

Is the tool suitable for CNC machining?
Yes, the indexable format and 25 mm shank make it suitable for integration into CNC machining centres as well as conventional machines

How does the indexable design reduce costs?
By replacing only the worn WCM‑0503 inserts rather than the entire body, the approach lowers ongoing tooling expenditure and simplifies spare-part management
