Indexable insert drill body U309TM – Ø 17.5 mm, 25 mm shank (Teknik Makina)

The Indexable insert drill body U309TM is a compact drilling solution for metalworking setups that require replaceable SOMT 0602 inserts and precise hole control in repetitive production tasks

• Precision Ø 17.5 mm drilling capacity
• 25 mm shank for secure clamping
• Compatible with SOMT 0602 inserts
• Cutting length 51 mm, total 129 mm

Stable holes for repeatable production results

The drill body’s Ø 17.5 mm cutting diameter and robust 25 mm shank are aimed at delivering consistent hole quality across series production. The relatively short overall length and balanced mass of 0.318 kg reduce vibration and help maintain tool runout within tighter tolerances, which is essential for achieving good surface finish and accurate hole position. Because the design accepts indexable inserts rather than relying on regrinding the body, setup differences between operators are minimised and reproducibility improves across shifts.

Flexible machining through an insert system

Adaptability is provided by the use of SOMT 0602 indexable inserts, a standard geometry that allows selection of grades and chipbreakers to suit a range of tasks. Compatibility with Taegutec inserts means that insert choice can be tailored to workpiece material and cutting conditions, enabling longer tool life and simplified inventory: worn cutting edges are replaced quickly, rather than re‑grinding the whole tool body. This modular approach reduces downtime and delivers a clear cost advantage over single‑use tools in medium‑volume machining.

Reduced downtime and easier handling at the bench

With a cutting length of 51 mm and total length of 129 mm, the tool body combines manoeuvrability and useful reach for most workshop spindles while keeping the centre of mass close to the clamping point. The shank length 56 mm allows secure seating in a toolholder or chuck, and the moderate mass helps with quick manual changes. Maintenance is straightforward: insert changes are performed at the seat, avoiding complex disassembly and keeping machine idle time to a minimum, which supports higher overall equipment effectiveness.

Practical guidance for selecting the right insert and use

The drill body itself provides the mechanical platform; the final machining capability depends on the insert grade and geometry chosen. For tougher alloys, tougher grades and positive rake designs are typical, whereas finishing of softer materials may favour fine‑edge grades. The compatibility with Taegutec SOMT 0602 inserts gives access to a wide range of grades and coatings from a known supplier, enabling tailored performance without replacing the drill body. For specific material guidance or cycle recommendations, consult the technical team.

FAQ

Which insert type fits this drill body?
The drill body accepts SOMT 0602 indexable inserts; Taegutec grades in this format are suitable for a wide range of applications with the U309TM tool body.

What clamping diameter is required?
A toolholder or chuck that accommodates a 25 mm shank is required to secure the U309TM correctly and maintain the specified runout performance.

How long is the effective cutting length?
The cutting length is 51 mm, which determines the maximum depth of hole achievable with the supplied cutting geometry.

Can the U309TM be used for different materials?
The drill body provides the mechanical platform; material suitability depends on the chosen insert grade — selecting the correct Taegutec SOMT 0602 grade will determine performance on specific alloys.

Is the total tool length compatible with compact spindles?
With a total length of 129 mm and a 56 mm shank length, the tool is designed to fit typical workshop spindles while keeping overhang moderate for stable cutting.
