Indexable drill body U939TM — Ø 39 mm, 78 mm cutting length (Teknik Makina)

The Indexable drill body U939TM is a 39 mm diameter tool body designed for indexable inserts and medium‑depth production drilling in precision machining environments

• Robust indexable design for high productivity
• Ø 39 mm cutting diameter for standard hole sizes
• 78 mm cutting length for medium‑deep holes
• 32 mm shank for secure clamping

Higher throughput through indexable insert technology

The body is engineered to accept SPMG 1104 inserts, enabling fast, repeatable edge changes and minimised downtime compared with solid drills. By combining a 32 mm shank with a balanced geometry and an overall length of 175 mm, the tool body offers stable cutting under cyclic loads; this reduces vibration and supports consistent hole quality across runs. The replaceable‑insert concept translates directly into a lower cost per hole and simplified tool inventory management.

Quick adaptation and secure mounting for production

Compatibility with leading insert suppliers (Taegutec, YG‑1) ensures ready availability of cutting grades and geometries suited to different operations. The 58 mm mounting length provides solid engagement in standard holders, while the body’s mass (1.007 kg) contributes to rigidity during plunge and peck drilling cycles. These attributes shorten setup time and help maintain spindle load stability during uninterrupted production, making the tool suitable for repeatable series work on CNC machines where predictable cycle times are essential.

Built for shopfloor reliability and easy maintenance

Constructed as a purpose‑built indexable drill body, the design emphasises serviceability: worn cutting edges are replaced in seconds, not hours, which supports sustained productivity and predictable maintenance intervals. The combination of a 39 mm diameter and 78 mm cutting length balances access to deeper features with chip evacuation requirements, delivering confident performance in component machining. Technical consultations are available to confirm holder compatibility or to select insert grades for specific tasks.

FAQ

Which inserts fit this drill body?
The U939TM accepts SPMG 1104 indexable inserts; compatible suppliers include Taegutec and YG‑1.

What holder size is required for mounting?
A 32 mm shank diameter and 58 mm mounting engagement are specified for secure clamping of the tool body.

How deep can this tool drill in one pass?
The tool body provides a 78 mm cutting length; the achievable penetration per pass depends on machine capability and chosen insert grade.

Is the U939TM suitable for series production?
Yes — the indexable design and quick insert changes make the U939TM well suited to series work where reduced downtime and repeatability are priorities.

What advantages do indexable inserts provide over solid drills?
Indexable inserts enable rapid edge replacement, lower cost per cutting edge and flexible selection of grades for different materials, all of which support consistent cycle times.
