Precision cut-off tools for accurate grooving and part-off operations
Cut-off tools are narrow holder systems for lathes designed to produce precise grooves and part-offs, offering reliable control when machining steels and other workpiece materials where clean separation is essential. They serve as either solid clamp-style holders or flat tool blades fitted with indexable carbide inserts, and when equipped with internal coolant channels they deliver high-pressure coolant directly to the insert to control heat and evacuate chips efficiently. Using these tools reduces the risk of chip jamming, surface damage and sudden tool failure while improving repeatability, particularly in deep grooving and tough materials where external coolant is insufficient. Key advantages include enhanced cutting stability, extended insert life and consistent part quality through optimised chip evacuation and thermal management.

Fast, reliable parting and grooving for precision turning
Parting and grooving tools, also referred to as parting blades, grooving tools or cut-off tools, are narrow carrier tools for lathes fitted with replaceable carbide inserts. Supplied as solid holders or flat blades, they are designed to cut precise grooves and to part finished components cleanly from the material bar.
Why internal coolant matters for deep cuts and tough materials
When used in simple form without internal coolant, the cutting fluid is applied via external machine nozzles; this is often sufficient for very shallow grooves and easily machinable materials. For deeper grooving and parting operations, however, the tool nearly encloses the slot so that external coolant cannot reach the cutting edge. Tools with internal coolant incorporate fine, integrated channels that deliver coolant under high pressure directly to the insert and beneath the chip. This targeted supply controls the intense heat in the confined cutting zone and uses flushing pressure to eject chips reliably, preventing chip jamming, surface damage and sudden tool breakage.
Clear operational benefits you can measure
- faster cycle times through reliable chip evacuation and uninterrupted cutting
- extended tool life thanks to effective heat control at the cutting edge
- consistent surface finish by avoiding chip re-cutting and scarring
- safer machining of hard or ductile materials due to reduced risk of tool fracture
- simplified setup when holders with integrated channels replace complex external coolant rigs

FAQ
When is internal coolant necessary for parting tools?
Internal coolant becomes necessary for deep grooving and parting or when machining hard or ductile materials; it delivers coolant directly to the insert and beneath the chip, which is critical when external nozzles can no longer reach the cutting edge.
Can parting tools be used without internal coolant?
Yes — for very shallow cuts and easily machinable materials, parting tools can be used with external machine coolant nozzles, but performance and tool life will drop markedly for deeper cuts.
How do parting tools prevent dangerous chip jamming?
Parting tools with integrated channels use high-pressure coolant to flush chips out of the narrow slot, preventing chips from becoming trapped and minimising the risk of surface damage and abrupt tool failure.
What should be considered when choosing a grooving insert and holder?
Select a combination that matches the required groove depth and material grade; holders offering integrated high-pressure channels are preferred for deep cuts or poor-chip-breaking materials to ensure heat control and reliable chip evacuation.
