SPMT090308 AH6225 Tungaloy insert for drilling (square 09, 90°)

SPMT090308 AH6225 Tungaloy insert is a square indexable insert for drilling systems, engineered for medium machining of stainless steel with a sharp yet stable cutting edge.

• PVD-coated carbide for consistent edge life
• Suitable for stainless steel and mixed conditions
• Square 09 form with single-sided chipbreaker
• With hole and 40°–60° countersink for secure clamping

Increased process reliability through optimised edge geometry

The square indexable design with a 90° seating angle and a 0.8 mm corner radius gives a balanced mix of robustness and precision. The PVD-coated carbide substrate is selected to maintain a sharp cutting edge under variable conditions, reducing the frequency of insert changes and supporting uninterrupted production runs. For drilling applications the defined seating and the cylindrical hole with single-sided countersink (40°–60°) ensure consistent clamping force and repeatable positioning in compatible drill bodies, contributing to dimensional stability in recurring cycles.

Clear advantages in machining stainless steel and mixed materials

This grade, marked AH6225, is specified as a universal sort for stainless steel, optimised for medium cutting parameters. The combination of coating and substrate improves wear resistance during typical drilling feeds and speeds while keeping chip formation stable thanks to the single-sided chipbreaker. For operations where varied workpiece batches occur, the insert’s balance of a sharp yet stable cutting edge offers a pragmatic compromise between high productivity and predictable tool life, lowering total machining costs over time.

Compatibility, mounting and handling in the workshop

The insert matches drill systems that accept a square 09 plate with 3.18 mm thickness and a 90° geometry; alignment to drill diameter and seat form is required when selecting the mating drill body. The presence of the central hole and one-sided countersink simplifies secure fixation with the appropriate clamping screw and key. When retrofitting or replacing, verify seat size and torque recommendations of the drill body to safeguard clamping integrity and to prevent premature wear or movement during operation.

Practical support and ordering information for production use

For workshop planning the insert serves as a reliable component for indexable drilling assemblies used in medium-duty production and maintenance tasks. If further technical data or compatibility checks are required—such as matching the insert to a specific drill body or recommending cutting parameters for particular stainless steel grades—Metav Werkzeuge provides technical advice and data sheets. Practical availability and logistics are handled via the distributor; typical enquiries cover mounting hardware, replacement intervals and recommended feeds/speeds for consistent surface quality.

FAQ

What materials is this insert designed for?
The SPMT090308 AH6225 Tungaloy insert is specified as a universal grade for stainless steel and performs reliably under mixed conditions typical of medium drilling operations.

How does the insert mount in a drill body?
The insert features a cylindrical central hole with a one-sided countersink (40°–60°) and is secured with the appropriate clamping screw; compatibility with the drill body must be verified by matching seat form and diameter.

What cutting-edge behaviour can be expected from AH6225?
AH6225 is a PVD-coated carbide grade balanced for a sharp, stable cutting edge, offering consistent chip formation and wear resistance during medium machining.

Is special handling or storage required for these inserts?
Store the inserts in a dry, clean environment to protect the PVD coating and avoid mechanical damage; handle with care during insertion to maintain the cutting-edge condition.

Which SKU identifies this product for ordering?
Order using SKU 6903311-Tungaloy or manufacturer SKU TUN6903311 to ensure the correct SPMT090308 AH6225 Tungaloy insert is supplied.
