ONHU 0705AN AH140 milling insert ONHU – DoFeed series by Tungaloy, octagonal, 135°

A precision indexable insert from the DoFeed family, the ONHU 0705AN AH140 is designed for high-feed milling, pocketing and face machining with large time-chip volumes at minimal axial engagement.

• High-feed DoFeed family
• PVD-coated AH140 grade
• Octagonal 135° geometry
• Double-sided chipbreaker

Maximise throughput with proven high-feed performance

The DoFeed design prioritises efficient material removal in short-cycle milling operations. The octagonal geometry and the 135° cutting angle enable shallow axial depths while maintaining substantial feed per tooth, so cycle times are reduced without sacrificing stability. The AH140 grade, a PVD-coated carbide, sustains a sharp cutting edge under repetitive loads, translating into measurable productivity gains when machining pockets and faces. This performance-focused configuration supports predictable tool life and process repeatability in production environments.

Consistent edge integrity and process security for repeatable parts

Tool life and component quality rely on reliable edge stability. The AH140 composition is optimised for resistance to wear and chipping, providing a balance between toughness and hardness suitable for intermittent cut conditions. The PVD-coated surface improves hardness and thermal resistance, which reduces flank wear and helps maintain surface finish across runs. With a double-sided chipbreaker pattern, the insert secures controllable chip formation and smoother evacuation, lowering the risk of rework and contributing to consistent part geometry.

Flexible geometry and secure clamping for diverse milling tasks

The octagonal, indexable design increases the number of usable cutting edges, reducing changeover frequency and inventory requirements. The insert features a cylindrical hole with a double countersink (40°–60°) for robust seating and torque transmission, and a nominal thickness of 5.56 mm matched to size 07 clamping pockets. These mechanical details combine to deliver stable clamp support and repeatable positioning, which is especially beneficial when switching between pocketing and face milling in mixed-production settings.

FAQ

What materials can be machined with this insert?
The ONHU 0705AN AH140 Tungaloy indexable insert (SKU 6861811-Tungaloy) is specified for general milling tasks and performs well on a wide range of steels and typical workshop materials encountered in face and pocket milling.

How does the AH140 grade affect tool life?
The AH140 PVD-coated carbide is engineered for wear and chipping resistance; the coating and substrate combination extend edge life under repetitive high-feed conditions, helping to reduce insert change frequency.

Which operations suit the DoFeed geometry best?
High-feed milling, pocketing and planing operations benefit from the DoFeed family geometry thanks to shallow axial cut requirements combined with high feeds per tooth, providing efficient material removal for short-cycle production.

How is the insert secured in the cutter body?
The insert uses a cylindrical hole with a double countersink (40°–60°) to ensure a secure, repeatable seat and reliable torque transmission when clamped in the compatible milling body.
