Tool Holder Code Breakdown
S: Screw-on style clamping system (uses a single central Torx screw to lock the insert securely into the pocket, offering minimal tool body interference).
D: 55-degree rhombic diamond insert shape (specifically designed for DCMT 11T3 style positive inserts).
N: 62.5-degree approach angle (lead angle) that provides clear clearance on both sides of the tool head.
C: 7-degree clearance angle for the insert pocket, helping to minimize friction against the workpiece.
N: Neutral cutting direction (the tool head sits perfectly inline with the center axis, allowing it to cut right-to-left or left-to-right).
2525: Shank cross-section dimensions, indicating a 25 mm height and a 25 mm width square steel shank.
M: Tool length indicator, denoting a total length of 150 mm from the base to the tool tip.
11: Designed to take inserts with an 11 mm cutting edge length (e.g., DCMT 11T304 or DCMT 11T308).
