The Sandvik Coromant TFA H10 right-hand uncoated carbide indexable milling insert has a triangle shape, a flat-top chipbreaker, and provides good wear resistance without limiting shock resistance for medium-machining face milling of aluminum in average-to-good machining conditions. H10 grade is made of uncoated fine-grained carbide that offers high edge sharpness.
This positive insert is used with the Sandvik Coromant T-Max AL system or other cutting systems for ANSI/ISO-standard triangle inserts that have a 0-degree lead angle for medium-machining face milling. The flat-top design increases tool strength. A flatted corner with parallel land improves surface finish on the workpiece. Triangle shape offers versatility of use and minimizes tool vibration. The insert has no hole, three cutting edges, a 60-degree tip angle, and a 25-degree primary clearance angle.
Milling inserts are coded according to their specific cutting and application capability (e.g., TFA 4 2 P3 R). Each section of the code represents details of the insert: shape, primary clearance angle, tolerances, insert size, insert thickness, 90-degree flatted corner with 25-degree facet clearance angle, and hand. Tolerance of the theoretical diameter of the insert is + or - 0.001”. Insert thickness tolerance is + or - 0.001”. Tolerance of the height of the insert is + or - 0.0002”. Insert shapes and sizes may have different inscribed circle (iC) measurements, which relate to ranges of cutting depths, speeds, lead angles, and feed rates. The iC is the largest circle that can be drawn within the edges of the insert shape. Generally, as the insert size and the iC become larger, the maximum cutting depth increases. Cutting depth influences the metal removal rate, the number of cuts, chip evacuation efficiency, and power required when using the insert. Indexable inserts are small cutting tools designed to remove material in external and internal cutting applications such as turning, milling, drilling, and grooving. They are held by an insert holder, have multiple cutting edges, and can be rotated when one edge wears down. Multiple inserts can accomplish a variety of cuts in one operation. An insert is either positive or negative, which refers to the rake or clearance angle at which the insert removes material.
Sandvik Coromant produces tools for turning, milling, and drilling. Headquartered in Sweden, the company manufactures tools used throughout the metalworking field, including the automotive and aerospace, die and mold, and general engineering industries. Matching Inserts to Holders
These inserts are used with the Sandvik Coromant T-Max AL tooling system or other cutting systems for ANSI/ISO-standard triangle inserts that have a 0-degree lead angle for square shoulder face milling and finishing applications. When used with these systems, this insert has 0-degree lead angle that directs most of the cutting forces radially in the direction of the feed.
