Sandviks CoroTurn XS CXS-05TH075MM-5115R 1025 Solid Carbide Internal Threading

The CXS-05TH075MM-5115R 1025 is a one-piece solid carbide threading tool from sandviks Coromant's CoroTurn® XS range — the series built for internal turning and threading in bores too small for conventional indexable bars.

This tool cuts a metric 60° internal thread with 0.75 mm pitch. Its cutting depth capacity is 0.41 mm, producing a theoretical thread height of 0.78 mm — a fine-pitch profile intended for small precision components rather than structural threads.

Because the tool is solid carbide rather than an indexable insert, rigidity comes from the body itself: a 5 mm connection diameter with 19.25 mm clamping length allows the tool to reach into a bore as small as 5.1 mm while keeping deflection low. The usable length is 15 mm, with a maximum overhang of 17.5 mm when mounted.

Grade 1025 is a PVD-coated carbide grade (TiAlN + TiN) on a high-cobalt substrate — a combination chosen for threading, where edge sharpness and wear resistance decide thread accuracy over the life of the edge.

• Internal metric threading 0.75 mm pitch — a fine-pitch profile for small precision parts, not general structural threads.
• Minimum bore diameter 5.1 mm — reaches bores that standard indexable threading bars cannot enter.
• Solid carbide body, 5 mm connection diameter — high rigidity for its size; no brazed joint to flex or fail.
• Single cutting edge (CEDC 1) — a solid tool, not an indexable insert: when the edge is worn the tool is replaced, so cost per part must be planned accordingly.
• Grade 1025, PVD TiAlN + TiN — sharp edge with wear resistance for predictable thread form.
• IT6 thread tolerance class capability — suitable for precision internal threads where fit class matters.
• ISO 956-1998 compliant — standard thread-turning tool geometry.

Read this carefully: 0.75 is the pitch, not the thread diameter. The tool cuts an internal thread in a bore of 5.1 mm and larger; it is not an M0.75 thread tool.

It is a solid carbide threading tool that clamps into a CoroTurn XS holder. The cutting tip and the body are one piece of carbide.

It is not an indexable insert. There is no spare edge to index — one edge per tool, then replacement. Some distributors list it as an "insert bar", which leads buyers to expect a replaceable tip; clarify this before quoting.

It is not an external threading tool. INT in the data means internal only; the external-thread counterpart is a different item number.

If the bore is smaller than 5.1 mm, the pitch is coarser than 0.75 mm, or the thread is external, this item will not work — a different XS tool or a different series is required.

Grade 1025 is a PVD-coated carbide grade with a TiAlN + TiN coating on a high-cobalt substrate. For threading, this matters in three ways:

• Edge sharpness — a thin PVD layer keeps the profile sharp, which directly affects thread flank accuracy.
• Wear resistance — keeps the thread form stable across the tool life instead of drifting toward the tolerance limit.
• Adhesion resistance — reduces built-up edge in gummy steels and stainless, a common cause of torn thread flanks.

• Small precision internal threads: fittings, connectors, sensor bodies, instrument parts
• Medical, watch and electronics components with fine-pitch metric threads
• Hydraulic and pneumatic small-bore ports
• Job shops threading small batches where a dedicated tap would be uneconomical or where the thread must be cut, not tapped

Less suitable for:

• coarse pitches and large diameters — use a conventional indexable threading bar;
• deep threads beyond the 15 mm usable length;
• external threads.

• Requires a CoroTurn XS clamping holder matching the 5 mm connection diameter — confirm the holder item before ordering.
• Clamping length 19.25 mm must be respected; insufficient clamping causes vibration and thread flank chatter.
• Keep overhang within 17.5 mm. Beyond that, deflection shows up as pitch error and taper.
• No through-coolant channel; apply external coolant or air blast for chip evacuation in blind holes.

• Sold as a single solid carbide tool (1 piece); confirm packing quantity with the actual packing list before publishing.
• Order by full designation: CXS-05TH075MM-5115R 1025
• Always state hand (R) and grade (1025) explicitly — both are part of the item number.

Is this an insert? No. It is a one-piece solid carbide tool with a single cutting edge; it clamps into a CoroTurn XS holder and is replaced when worn.

What thread does it cut? An internal metric 60° thread with 0.75 mm pitch, in bores from 5.1 mm.

Can it cut external threads? No. This item is internal (INT) only.

Does it need a holder? Yes — a CoroTurn XS holder with 5 mm connection. The tool alone cannot be mounted directly.

Does 1025 mean a size? No. 1025 is the carbide grade; the size information is in the -05TH075MM-5115R part.
