The DCKNL 2525 M19 is an ISO-standard, left-handed indexable external turning tool holder engineered for heavy-duty metal removal, roughing, and profiling operations on CNC and conventional lathe machines .
The designation indicates a Double-clamp system, C-type 80° rhombic insert, K-style 75° approach angle, N-type 0° clearance, and Left-hand design. The 25x25mm shank, 150mm length, and pocket size (19) support heavy-duty CNMG 1906xx inserts for high-volume material removal.
Every character in DCKNL 2525 M19 defines a precise physical or geometric parameter according to international manufacturing standards:
Code
Parameter
Description & Engineering Purpose
D
Clamping System
Double-Clamping / Top-Rigid Clamp with Pin. This uses both a top clamp and a hole hook mechanism. It provides maximum stability against multi-directional cutting forces, preventing the insert from shifting during heavy roughing.
C
Insert Geometry
80° Rhombic (Diamond-shaped). Designed exclusively to hold CN__ style inserts. This shape provides an excellent balance of cutting edge strength and profiling flexibility.
K
Tool Style (Lead Angle)
75° Approach Angle (Lead Angle). The tool approaches the workpiece at 75°. This geometry distributes the cutting force over a longer length of the cutting edge, reducing localized thermal shock and allowing for higher feed rates compared to a 95° holder.
N
Clearance Angle
0° Negative Clearance. The insert sits flat (perpendicular) in the pocket. This design allows you to use a negative insert, meaning you can flip the insert over to use both the top and bottom faces (doubling the number of available cutting edges).
L
Cutting Direction
Left-Handed Tool. The tool cuts moving from the headstock toward the tailstock, or requires reversing the spindle rotation/mounting configuration depending on your CNC turret setup.
2525
Shank Dimensions
25mm Height × 25mm Width. A standard square shank size. It fits directly into standard CNC turret slots or conventional tool posts without requiring specialized reduction sleeves.
M
Tool Length
150mm Functional Length. This is the total length from the back of the steel shank to the absolute tip of the cutting point.
19
Insert Size (Inscribed Circle)
19mm Edge Length Compatibility. The pocket seat is explicitly ground to house massive CNMG 1906xx style inserts.
