Product Description
The CMT HSK Chuck for Grooving Blade (183.421.30) is a precision saw blade arbor engineered for CNC machining centers, point-to-point machines, and CNC routers. Featuring an HSK-F63 shank interface, this chuck delivers a fast, rigid spindle connection that supports accurate grooving and slotting operations in wood-based panel materials. With a 30mm bore and a flange diameter of 98mm, it accepts grooving blades up to 300mm (12 inch) in diameter, making it a versatile toolholder for demanding industrial panel processing. Bidirectional RH-LH rotation compatibility adds further flexibility for a variety of CNC setups and cutting strategies.
Key Features
- HSK-F63 shank interface - provides a fast, rigid connection to the CNC machine spindle, minimizing runout and ensuring precise, repeatable grooving and slotting results.
- 30mm bore diameter - accepts standard 30mm bore grooving saw blades, giving operators access to a wide range of compatible industrial blades for panel machining.
- 98mm flange diameter - provides a stable clamping platform that keeps grooving blades securely seated during high-speed CNC operations.
- 94mm total length - the overall chuck length is optimized for clearance and reach on CNC machining centers handling grooving and slotting tasks.
- Maximum blade capacity up to 300mm (12 inch) - accommodates a large range of grooving blade sizes, supporting deep panel cuts and versatile groove widths.
- RH-LH bidirectional rotation - works with both right-hand and left-hand spindle rotation, enabling use across a broader variety of CNC machine configurations.
- Pin hole specification 6/M6/80 - purpose-engineered pin hole geometry ensures positive blade drive and secure torque transfer during grooving operations.
Why This Product
- The HSK-F63 shank standard is widely adopted in industrial CNC machining centers and point-to-point machines, making this chuck a direct-fit solution for facilities already running HSK tooling systems - no adapters or modifications needed.
- With support for saw blades up to 300mm in diameter and a 30mm bore, this arbor covers the most common grooving blade dimensions used in hardwood, softwood, plywood, and MDF panel processing.
- Bidirectional RH-LH rotation compatibility means this single chuck can be used on machines with differing spindle rotation directions, reducing the need for separate toolholders for different machines.
- The precise 94mm total length and 98mm flange diameter are matched to the HSK-F63 interface specification, ensuring the chuck fits within the dimensional envelope of CNC spindle setups designed for grooving operations without clearance issues.

Frequently Asked Questions
What is the maximum saw blade diameter this chuck can accommodate?
The CMT 183.421.30 HSK chuck is rated to accept grooving blades up to 300mm (12 inch) in diameter. Always respect the maximum RPM indicated for any blade mounted in this chuck.
Is this chuck compatible with both right-hand and left-hand spindle rotation?
Yes. The 183.421.30 supports both RH (right-hand) and LH (left-hand) rotation, making it compatible with CNC machining centers and CNC routers that use either spindle direction.
What bore diameter does this HSK grooving chuck accept?
This chuck is designed for grooving blades with a 30mm bore. The bore specification is F=30x6.5mm as noted in the product technical data.
What shank type does the CMT 183.421.30 use, and which machines is it intended for?
The 183.421.30 uses an HSK-F63 shank, which is a standard taper used on CNC machining centers, CNC routers, and point-to-point machines equipped with HSK-63F spindle interfaces.
