PARTING & GROOVING

Parting & Grooving Tool Holders

Toolholders, blades and support systems for cut-off, external grooving, internal grooving and profiling operations.

Select the holder by machining operation, insert or blade system, groove width, cutting depth, holder style, rigidity and coolant requirement. Correct holder selection improves insert support, chip evacuation, dimensional consistency and tool life.

HOLDER SELECTION

Choose the Right Holder

Start with the machining operation, then confirm the holder style, insert system and required cutting depth.

PARTING / CUT-OFF Blade or Rigid Holder

Choose a holder or blade system with sufficient cutting depth, stable insert support and effective chip evacuation.

EXTERNAL GROOVING Groove Width & Depth

Match the holder to the required groove width, depth, component clearance and insert geometry.

INTERNAL GROOVING Bore Access & Clearance

Confirm minimum bore diameter, holder overhang, internal clearance and insert accessibility.

RELIEF / PROFILING Access Around Features

Use a holder geometry that provides suitable access for relief grooves, profiling and contour machining.

HOLDER STYLE

Match the Holder Style to the Application

Different holder systems provide different levels of rigidity, cutting depth, accessibility and insert support.

DIRECT HOLDER Compact & Rigid

Suitable for general external grooving and parting applications where a compact holder body provides sufficient reach.

BLADE SYSTEM Deep Parting Capability

Blade-style systems provide extended cutting depth and are commonly used for cut-off and deeper grooves.

SUPPORT BLOCK Secure Blade Support

Blade blocks and support systems improve rigidity and securely locate the blade during deeper cuts.

SELECTION FACTORS

Check the Complete Tooling Setup

The holder must match the insert, machine setup and cutting conditions.

Insert / Blade Compatibility

Confirm the selected insert or blade is designed for the holder system.

Groove / Cut Width

Match holder and insert width to the required groove or parting width.

Maximum Cutting Depth

Check holder or blade reach against the required groove depth or cut-off diameter.

Holder Size

Match holder shank size or blade block size to the machine turret or tool post.

Rigidity & Overhang

Keep overhang as short as practical and use sufficient holder cross-section for stable cutting.

Coolant Delivery

Effective coolant delivery improves chip evacuation, temperature control and tool life in narrow cuts.

STABILITY

Rigidity Matters in Narrow Cuts

Parting and grooving tools operate with narrow cutting edges, so holder stability and insert support are especially important.

MINIMUM OVERHANG Reduce Deflection

Keep holder and blade extension as short as the component geometry allows.

SECURE SUPPORT Protect the Cutting Edge

Ensure the insert or blade is fully supported and correctly clamped.

GOOD CHIP FLOW Prevent Chip Packing

Correct geometry and coolant help chips leave narrow grooves without recutting or jamming.

QUICK SELECTION

Practical Holder Selection

General External Grooving

Start with a rigid direct holder matched to the required insert width and groove depth.

Deep Parting

Consider a blade system with strong support, minimum overhang and effective coolant.

Internal Grooving

Confirm minimum bore diameter, holder clearance and internal reach before selecting the system.

Difficult-to-Machine Materials

Prioritise rigidity, coolant delivery and compatible insert geometry for heat and chip control.
