NEW – 2025

This combination of specifications makes the holder relevant to professional machining operations requiring the exact Sandvik Coromant model and compatible cutting-tool components.

The 1 × 1 inch shank configuration is particularly important for machine compatibility, while the left-hand cutting direction helps identify the appropriate tooling arrangement.

The Q-Cut Size 40 cutting interface is another defining characteristic of this holder.

The supplied 32.004 mm maximum cutting depth and 41.656 mm maximum cantilever length provide important references for evaluating the holder's intended machining envelope and installation requirements.

💎 T-Max Q-Cut Toolholding System

The T-Max Q-Cut product family is associated with professional parting and grooving applications.

For the L151.21-16-40A, the supplied cutting interface is:

Q-Cut Size 40 – N151.2-400-5E

The cutting interface is an important characteristic when selecting compatible inserts and replacement components.

Professional machining operations require correct insert selection, secure clamping and appropriate cutting parameters.

The supplied specifications confirm the Q-Cut Size 40 interface but do not establish the exact included insert, insert grade or clamping accessories.

Buyers should verify the required cutting components using the manufacturer's technical documentation.

The correct toolholder and cutting insert combination is essential for reliable parting and grooving operations.

The supplied interface designation provides a useful reference for identifying the relevant cutting system.

⚙️ 1 × 1 Inch Rectangular Shank

The supplied machine-side adapter interface is:

ADINTM / ADINTMS – Rectangular Shank, Inch: 1 × 1

The corresponding shaft dimensions are:

• Width (B): 25.4 mm
• Height (H): 25.4 mm
• Imperial Width: 1 inch
• Imperial Height: 1 inch
• Calculated Cross-Sectional Area: 645.16 mm²

The 1 × 1 inch shank is a defining feature of this tool holder.

Its dimensions are important when evaluating compatibility with industrial turning machines using inch-based toolholding blocks.

The 25.4 × 25.4 mm shaft configuration provides a clearly identified machine-side mounting cross-section.

This dimension should be compared with the machine's toolholding block and turret arrangement before installation.

The calculated cross-sectional area is a geometric value and does not represent a manufacturer-certified rigidity or load rating.

Before installation, the machine's tool block, turret configuration, cutting-edge position and clamping requirements should be checked.

The shank dimensions alone do not guarantee compatibility with every CNC lathe or conventional turning machine.

🔩 Functional Width – 25.7048 mm

The supplied functional width is:

W / WF = 25.7048 mm

Equivalent values:

• 25.7048 mm
• 2.57048 cm
• 1.012 inches

The functional width is an important dimensional characteristic for evaluating tool geometry and installation clearance.

It should not be confused with the cutting width or the width of a groove produced during machining.

The actual cutting width depends on the compatible insert and its cutting-edge geometry.

The insert cutting width has not been separately supplied.

For professional machining applications, functional width can be relevant when checking tool positioning and clearance between adjacent turret stations.

The supplied value of 25.7048 mm should therefore be used as a toolholder dimension rather than a cutting-width specification.

🛠 Functional Height – 25.4 mm

The supplied functional height is:

HF = 25.4 mm

This corresponds to:

• 25.4 mm
• 2.54 cm
• 1 inch

The functional height is relevant to machine-side installation and tool positioning.

Although it is numerically equal to the supplied shaft height, the exact cutting-edge position should be confirmed using the manufacturer's dimensional drawing.

For CNC turning operations, the functional height can be an important factor when evaluating the tool's relationship to the machine centerline.

The complete tool geometry should be verified before installation.

📏 Functional Length – 152.4 mm

The supplied functional length is:

L / LF = 152.4 mm

Equivalent values:

• 152.4 mm
• 15.24 cm
• 6 inches

This dimension is relevant to tool positioning and installation planning.

However, functional length must not be confused with maximum permissible cantilever length.

For this model, the supplied maximum cantilever length is 41.656 mm.

The maximum cutting depth is separately specified as 32.004 mm.

These dimensions represent different characteristics of the holder and should be evaluated independently.

The 152.4 mm functional length is relevant to the holder's dimensional configuration, while the 41.656 mm maximum cantilever length is a separate limitation for tool projection.

Correct interpretation of these dimensions is important for professional machining setup and toolholder compatibility evaluation.

🔥 Parting & Grooving Applications

The SANDVIK COROMANT L151.21-16-40A is identified as a shank tool for parting and grooving.

Its principal machining-related specifications include:

• Cutting Direction: Left-Hand
• Cutting Interface: Q-Cut Size 40
• Cutting Interface Reference: N151.2-400-5E
• Parting Diameter (CUTDIA): Not supplied

The 32.004 mm maximum cutting depth provides a defined dimensional limit for evaluating the tool's machining envelope.

The 41.656 mm maximum cantilever length is relevant when determining permissible tool projection during installation.

These specifications describe different characteristics and should not be treated as interchangeable.

The parting diameter has not been supplied and should not be calculated or assumed from the maximum cutting depth without manufacturer confirmation.

Correct insert selection, machine rigidity, tool orientation and cutting conditions remain essential for professional parting and grooving operations.

The actual suitability for a particular workpiece and cutting operation depends on the selected insert, machine setup and operating conditions.

📐 Left-Hand Cutting Configuration

The cutting direction is explicitly specified as:

HAND = L – Left-Hand

This characteristic is important when selecting tooling for a particular turret arrangement or cutting direction.

The left-hand configuration should be checked against the intended machining operation and machine setup.

The supplied information confirms the cutting direction but does not separately identify the approach angle, insert rake geometry or cutting-edge position.

These details should be verified before installation.

For professional CNC turning operations, selecting the correct tool orientation is essential to achieving the intended cutting arrangement.

The HAND = L specification provides a clear reference for identifying this holder as a left-hand configuration.
