Frequently Asked Questions

Q What is the difference between HSK-A-SLN and HSK-A-SLNB side-lock holders?

The HSK-A-SLN series is a standard side-lock holder designed for general CNC machining applications, available in HSK50A, HSK63A, and HSK100A interfaces. The HSK-A-SLNB series features a shorter body design optimized for applications requiring reduced overhang, improving rigidity and vibration damping in confined workspaces. Both series use compatible side-lock screws but differ in overall length (L) and body geometry.

Q What taper interfaces are available for the side-lock holder series?

The side-lock holders are available across multiple taper interfaces to suit different machine spindles: HSK50A, HSK63A, and HSK100A for the HSK series; BT30 and BT50 for the BT series; and SK30, SK40, and SK50 for the SK series. Each interface type is compatible with its respective machine spindle standard.

Q What shank diameters (d1) are supported by these side-lock holders?

The side-lock holders support a wide range of shank diameters to accommodate various cutting tools. Available d1 sizes include 6 mm, 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, 25 mm, 32 mm, 40 mm, 42 mm, 50 mm, and 50.8 mm. Larger shank diameters (25 mm and above) typically use Figure B configuration with an extended side-lock screw design.

Q Do wrenches come included with the side-lock holders?

No, wrenches are not included with any of the side-lock holders in these series. Wrenches must be ordered separately. Please refer to the side-lock screw specification listed in the product table (e.g., M060U100, M180Z200P) to identify and order the correct wrench for your specific holder model.

Q What is the significance of Figure A and Figure B in the specification tables?

Figure A and Figure B refer to two different structural configurations of the side-lock holder. Figure A is the standard configuration used for smaller shank diameters (typically up to 20 mm), where the L2 dimension is not applicable. Figure B is used for larger shank diameters (typically 25 mm and above) and features an additional body section with a defined L2 dimension, providing enhanced clamping strength and torque transmission for heavier cutting operations.

Q How do I select the correct side-lock holder for my application?

To select the correct side-lock holder, consider the following parameters: (1) Spindle interface type — match the holder series (HSK, BT, or SK) to your machine spindle; (2) Shank diameter (d1) — match to your cutting tool shank size; (3) Overall length (L) — choose based on your workpiece depth and clearance requirements; (4) Weight — consider the holder weight relative to your spindle's load capacity. For high-speed applications, HSK-type holders are recommended due to their superior balance and rigidity.
