Solid Carbide Long-Reach Thread Mill Overview<\/h2>\n

These 60\u00b0 solid carbide long-reach thread mills are designed for precision internal threading in deep bores, recessed features and restricted-access components. The Single-Form Long-Reach Series provides flexible pitch coverage with a 100 mm overall length, while the 3-Tooth Long-Reach Metric Series covers dedicated M1.6\u2013M14 threads in 75 and 100 mm lengths. Relieved necks provide clearance behind the cutting section, and the choice of single-form or three-tooth geometry allows users to balance pitch flexibility, reach and machining productivity.<\/p>\n

Key Configuration<\/h3>\n
\n
\n

Single-Form Long-Reach Series<\/h4>\n

Broad tool-specific pitch intervals from 0.25\u20130.35 mm up to 2.0\u20135.0 mm, with \u00d81.05\u2013\u00d816 mm cutters and a fixed 100 mm overall length.<\/p>\n<\/div>\n

\n

3-Tooth Long-Reach Metric Series<\/h4>\n

Three-tooth cutting geometry increases axial thread coverage for dedicated M1.6\u2013M14 metric pitches. Standard models use three flutes through M6 and four flutes from M8, with 75 or 100 mm lengths by size.<\/p>\n<\/div>\n

\n

Relieved-Neck Access<\/h4>\n

Reduced neck diameter d2 provides clearance behind the cutting section for recessed threads and deep internal features while L1 defines the usable reach.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

Key Product Advantages<\/h3>\n
\n
\n
LR<\/div>\n

Deep-Bore Access<\/h4>\n

Long overall lengths and relieved necks reach internal threads behind shoulders or inside recessed bores.<\/p>\n<\/div>\n

\n
SF<\/div>\n

Flexible Pitch Coverage<\/h4>\n

Single-form models cover defined pitch intervals and reduce inventory for mixed thread-diameter production.<\/p>\n<\/div>\n

\n
3T<\/div>\n

Three-Tooth Productivity<\/h4>\n

The three-tooth cutting section covers more axial thread length per toolpath than a single-form design, supporting efficient metric thread production.<\/p>\n<\/div>\n

\n
C<\/div>\n

Solid Carbide Rigidity<\/h4>\n

Fine-grain carbide supports dimensional stability, wear resistance and controlled cutting at extended reach.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Application Note:<\/strong> Extended overhang reduces tool stiffness. Start conservatively, use a low-runout precision holder, keep the cutting zone clear and optimize speed, feed and radial engagement after inspecting the first thread.<\/div>\n<\/section>\n
