Corner milling head by Teknik Makina — 100 mm, internal coolant

The Corner milling head for APMT 11T3 indexable inserts is a compact, coolant-fed cutting head engineered for precision face and shoulder milling in production environments.

• 100 mm diameter, robust construction
• Internal coolant for stable chip evacuation
• 90° cutting angle for square shoulder milling
• Compatible with APMT 11T3 inserts (Korloy)

Greater stability for higher material removal rates

The large 100 mm body diameter and solid construction deliver enhanced rigidity that reduces chatter and improves surface finish in demanding operations. With an overall length of 63 mm, the head offers a compact overhang that permits higher feed rates while maintaining dimensional accuracy. The result is predictable process behaviour and longer insert life, which reduces unplanned tooling changes and supports continuous production.

Coolant-fed cutter for controlled cutting temperatures

Integrated internal coolant ensures direct lubrication and cooling at the cutting zone, which lowers thermal load on the insert and workpiece. This feature supports consistent cutting conditions, particularly when machining tougher alloys or when higher cutting speeds are required. By promoting efficient chip evacuation and heat dissipation, the coolant channel contributes to steady tool performance and reduced risk of thermal damage.

Quick, secure insert clamping for minimal downtime

Designed for APMT 11T3 indexable inserts, the head uses a Torx clamping system (key Torx T8) with screws M2.5x5.5 to secure each insert reliably. The straightforward clamping geometry enables fast index changes and repeatable seating, so setup times are shortened and assembly errors are minimised. Compatibility with Korloy inserts offers availability of proven grades and geometries for a range of materials.

Right-angled cutting for precise shoulder and face work

With a 90° cutting angle, the tool head excels at square shoulder milling and face operations where perpendicular contact and true shoulders are required. The configuration is suitable for mixed production workshops and small-series manufacturing where flexibility and repeatable accuracy are priorities. The head’s ten cutting positions support extended service intervals and cost-effective operation.

FAQ

What inserts fit this cutter head?
The head accepts APMT 11T3 indexable inserts; Korloy grades are noted as compatible for a range of materials and cutting conditions.

Does the head provide internal coolant?
Yes, internal coolant is integrated to ensure direct delivery of lubricant and cooling to the cutting edge, improving stability and tool life for the corner milling head T258-1TM.

What is the cutting geometry and where is it used?
The tool features a 90° cutting angle, making it well suited for square shoulder and face milling operations in production and workshop environments.

How are the inserts secured?
Inserts are clamped with Torx T8 screws (size M2.5x5.5) for secure, repeatable seating and fast index changes.

Is the component suitable for heavy-duty milling?
The 100 mm diameter and robust design provide high rigidity; combined with internal coolant and multiple cutting edges, the head supports stable milling in many production tasks (material suitability should be checked against insert grade).
